DEPT/DIV CALCULATION NO. IP-C-0067 REVISION: I SHEET C/NSED 3 of 39 1.0 OBJECTIVE 1.1 To determine the instrument uncertainty, Allowable Value, Setpoint, As-Found Tolerance (AFT) and As-Left Tolerance (ALT) associated with an extended 24 months fuel cvle for Main Steam Line Pressure - Low instrument loops. 1.2 This calculation evaluates the adequacy of the current Allowable Value and setpoints in relationship to the results of 1.1 above. 1.3 This calculation is applicable for the following instruments: MS Press at Stop Valve 3 Transmitter IB21N076A MS Press at Stop Valve 4 Transmitter lB21N076B MS Press at Stop Valve I Transmitter IB21N076C MS Press at Stop Valve 2 Transmitter I B21N076D MS Press at Stop Valve 3 Analog Trip Module I B21N676A MS Press at Stop Valve 4 Analog Trip Module I B21N676B MS Press at Stop Valve I Analog Trip Module I B2 IN676C MS Press at Stop Valve 2 Analog Trip Module I B2 IN676D
DEPT/DIV CALCULATION NO. IP-C-0067 REVISION: I SHEET C/NSED 4of 39 2.0 ASSUMPTIONS 2.1 Published instrument vendor specifications are considered to be 2z values unless specific information is available to indicate otherwise (Reference 6.1, Appendix 1, Section 1.1 1). 2.2 Temperature, humidity, power supply, and ambient pressure errors have been incorporated when provided by the manufacturer. Otherwise, these errors are assumed to be included in the manufacturer's accuracy or repeatability specifications (Reference 6.1, Appendix 1, Section 1.1 1). 2.3 Changes in ambient humidity are assumed to have a negligible effect on the uncertainty of the instruments used in these loops (Reference 6.1, Appendix 1, Section 1.1 1). 2.4 Normal radiation induced errors have been incorporated when provided by the manufacturer. Otherwise, these errors are assumed to be small and capable of being adjusted out each time the instrument is calibrated. Therefore, unless specifically provided, normal radiation errors can be assumed to be included within the
. instrument drift errors (Reference 6.1, Appendix I, Section 1.1 1).
2.5 If the manufacturer's instrument performance data does not specify Span, Calibrated Span (CS), Upper Range Limit (URL), etc. the calculation will assume URL because it will result in the most conservative estimate of instrument uncertainty. In all cases the URL is greater than or equal to the CS and it is conservative to use the URL in calculating instrument uncertainties. This is because, by definition, URL is the maximum upper calibrated span limit for the device (Reference 6.1, Appendix I, Section 1.1 1). 2.6 This analysis assumes that the instrument power supply stability (PSS) is within
+5% (+/-1.2 Vdc) of a nominal 24 Vdc (Reference 6.1, Appendix 1, Section 1.11).
2.7 The effects of normal vibration (or a minor seismic ewnt that does not cause an unusual event) on a component are assumed to be calibrated out on a periodic basis. As such, the uncertainty associated with this effect is assumed to be negligible and included within the instrument drift errors. Abnormal vibrations, e.g., levels that produce noticeable effects on equipment, are considered abnormal events that require maintenance or equipment modification (Reference 6.1, Appendix I, Section 1.1 1). 2.8 Evaluation of M&TE errors is based on the assumption that the test equipment listed in Analysis Section 7.0 is used. Use of test equipment less accurate than that listed will require evaluation of the effect on calculation results (Reference 6.1, Appendix I, Section I.1 1). 2.9 It is assumed that the M&TE listed in Section 7.0 is calibrated to the required manufacturer's recommendations and within the manufacturer's required
DEPT/DIV CALCULATION NO. IP-C-0067 REVISION: 1 SHEET C/NSED 5 of 39 environmental conditions. Temperature related errors are based on the difference between the Calibration Lab temperature and the worst case temperature at which the device is used (Reference 6.1, Appendix 1, Section 1.1 1). 2.10 It is assumed that the reference standards used for calibrating M&TE or Calibration tools shall have uncertainty requirements of not more than 1/4 of the tolerance of the equipment being calibrated. A greater uncertainty may be acceptable as limited by "State of the Art". It is generally accepted that the published vendor accuracy of the M&TE or Calibration tool includes the uncertainty of the calibration standard M&TE when the 4:1 accuracy standard is satisfied. Hence, Calibration Standard uncertainty is considered negligible to the overall calibration error term and can be ignored. This assumption is based primarily upon inherent M&TE conservatism built into the calculation. Per assumption [2.11], this calculation considers the combined M&TE vendor or reference accuracy used for calibration satisfies 1:1 accuracy ratio to the instrument under calibration. This ratio bounds the upper accuracy limit on Calibration tool equal to the Vendor's Accuracy (VA) specification for the device under calibration. Use of M&TE more accurate than 1:1 is conservative to this assumption and thereby acceptable without impacting the results of this calculation (Reference 6.1, Appendix 1, Section 1.1 1). 2.11 It is assumed that when M&TE is not specified uniquely in a controlling calibration procedure (e.g., Surveillance Procedure or Preventive Maintenance Procedure), the combined M&TE vendor or reference accuracy used for calibration satisfies a 1:1 accuracy ratio to the instrument under calibration. This accuracy ratio establishes the limit on selected M&TE equal to the Vendor's Accuracy (VA) requirement. Further, M&TE uncertainty assumed per this discussion, is considered a 3a value regardless of the confidence associated with the related VA term (Reference 6.1, Appendix 1, Section I.1 1). 2.12 Vendor performance specifications and qualification test reports do not provide an instrument error specification for the effects of EMI and RFI. As such, any effect related to EMI and RFI is assumed to be negligible (Reference 6.1, Section 4.3.1 and Appendix A, Section A.2.1). 2.13 If the instrument vendor provides no drift information and there is no clear basis for assuming drift is zero, it may be conservatively assumed that the drift over the entire calibration period equals Vendor Accuracy (i.e., VD = VA 2a) (Reference 6.1, Appendix I, Section 1.1 1). 2.14 Per Reference 6.1, Section 4.1.2.2, CPS assumes that functions associated with setpoints will function in their first trip during an event, the point in time when they and they alone are most relied upon for plant safety. Worst case environmental conditions, that assume failure of protective equipment, or conditions that would only exist after the point in time where manual operation action is expected, are not applicable to the automatic trip functions that are expected or relied upon to occur in the early part of the event.
DEPT/DIV CALCULATION NO. IP-C-0067 REVISION: 1 SHEET C/NSED 6of 39 For the Main Steam Isolation functions initiated by Main Steam Line Pressure-Low, the protective actions occur within seconds of the event initiation. Per Input 4.9, there is no required accident function time of the Main Steam Line Pressure-Low components. This is a period before reactor power has been significantly reduced and before the operator has had an opportunity to take control of the plant situation. During this early period of the postulated event the core is not uncovered, therefore, no core damage has occurred and no radioactive release would be expected. As such, this calculation assumes the worst rational environmental condition at the time of trip operation will not result in harsh temperature conditions concurrent with high humidity, particularly steam environments, or harsh radiation levels. Therefore, transmitter errors due to accident radiation effects and the error attributed to insulation resistance accuracy (IRA) are negligible. In high temperature environments the transmitter errors due to Accuracy Temperature Effect are increased. However, a high temperature environment with a significant impact on transmitter accuracy will not form immediately at the time of reactor scram. Therefore, Accuracy Temperature Effect errors associated with normal operating temperatures are bounding for the Main Steam Line Pressure-Low transmitters. 2.15 Reference 6.1, Appendix C, Section C.3.14 states, "... there are no realistic, identifiable events which could result in a pipe break inside the containment of the magnitude required to cause a loss-of-coolant accident coincident with a safe shutdown earthquake." Therefore, this calculation considers the effects of the seismic event and loss-of-coolant accident independently to establish the worst case scenario for the instrumentation being evaluated. 2.16 As indicated in Input 4.9.11, Inputs 4.5.13 and 4.5.14 are schematic diagrams for Analog Trip Module 147D8505G001 and Inputs 4.5.15 and 4.5.16 are schematic diagrams for Analog Trip Module (ATM) 147D8505G005. Comparison of both sets of schematic diagrams indicates no significant difference schematically between the two models. It is, therefore, assumed that ATM Models 147D8505G001 and 147D8505G005 are functionally the same.
DEPT/DIV CALCULATION NO. IP-C-0067 REVISION: 1 SHEET C/NSED 7 of 39 3.0 lMETHODOLOGY 3.1 INSTRUMENT UNCERTAINTY This calculation will determine the instrument uncertainty associated with the Main Steam Line Pressure - Low isolation control loop. The Evaluation will determine the As-Found Tolerance, As-Left Tolerance, and the loop nominal trip setpoint (NTSP). Instrument uncertainty will be determined in accordance with CI-01.00 (Reference 6.1). The evaluation will then compare the current setpoint with the results determined by this calculation. The more conservative setpoint will be used. M&TE error will be determined from the results of Calculation IP-C-0089 (Input 4.6.1) which uses building temperature minimum and maximums to develop the uncertainty, and review of the corresponding loop and device calibration procedures (Inputs 4.9.1 and 4.9.3). 3.2 APPLICATION OF DRIFTANALYSIS RESULTS This calculation will utilize the equations as defined in CI-01.00 with the exception of the following changes that are required to integrate the calculated 915-day Drift (DTIc) into the analyses. As defined in NES-EIC-20.04, Appendix J, when formal Drift Analyses have been performed, the calculated 915-day Drift (DTIc) may replace the VAL, DL and CL variables collectively in the equations. For calculations utilizing the CI-01.00 (Reference 6.1) equations for Setpoints with Analytical Limit, the equations for Loop Calibration Error (CL), Loop Drift (DL), Nominal Trip Setpoint (NTSP) and As-Found Tolerance (AFTL) will be impacted and will require some modification. The existing Loop Accuracy (AL), Allowable Value (AV) and As-Left Tolerance (ALTL) equations identified in CI-01.00 will NOT be modified. The Loop Calibration Error (CL) and Loop Drift (DL) terms are components of the calculated 915-day Drift (DTIc) and will be replaced with DTIc collectively in equations containing all of these variables. The Loop Calibration Error (CL) and Loop Drift (DL) terms may be calculated using the existing equations identified in CI-01.00, but the results will be used for comparison purposes only. The existing Loop Calibration Error (CL) and Loop Drift (DL) equations identified in CI-01.00 will NOT be modified when used to calculate these variables.
DEPT/DIV CALCULATION NO. IP-C-0067 REVISION: I SHEET C/NSED 8 of 39 As-Found Tolerance (AFT) By definition, the As-Found Tolerance (AFTL) may be replaced with DTIc, where DTIc is the calculated 915-day Drift. AFTL = DTIc However, the As-Found Tolerance (AFTL) term may be calculated using the equation identified in CI-01.00 for comparison purposes only. The existing As-Found Tolerance (AFTL) equation identified in CI-01.00 will NOT be modified when used to calculate the As-Found Tolerance (AFTL). Nominal Trip Setpoint Calculation The Nominal Trip Setpoint (NTSP) equations are revised as indicated below depending on the direction of process variable change when approaching the Analytical Limit. For process variables that increase to trip, NTSP = AV - DTIc For process variables that decrease to trip, NTSP = AV + DTIc

Main steam line low pressure is monitored by four pressure transmitters that sense pressure on the main steam line header downstream of the outboard main steam line isolation valves. The I B21N076A-D transmitter signal outputs are input to the ATM circuits IB21N676A-D. The trip outputs of the ATMs are transmitted to a 2-out-of-4 logic Primary Containment and Drywell MSIV circuitry. The Allowable Value was selected to be high enough to prevent excessive RPV depressurization. 7.2 LOOP DIAGRAM Per Inputs 4.1.1 and 4.5.1, Pressure Transmitter Analog Trip Module IB21N076B & C 1B21N676B & C Main Steam Tunnel (T-8) Main Control Room (M-24) Pressure Transmitter Analog Trip Module IB21N076A & D IB21N676A & D Turbine Building (H-54) Main Control Room (M-24)

IP-C-0067 REVISION: I SHEET C/NSED 31 of 39 7.7 PROCESS MEASUREMENT ACCURACY (PMA) The Main Steam Line Pressure-Low process is sensed through instrument lines connected to the main steam line header. Because of the steam pressure process being measured, the PMA effects associated with these transmitters are negligible. The change in density of the steam within the sensing lines is insignificant as compared to the high pressures being monitored. The instrument lines are installed with a slope that drains back into the transmitters. The slope keeps the sensing line full of water/condensate, which would therefore minimize PMA effects. Therefore, the PMA is considered negligible. PMA =0 7.8 PRIMARY ELEMENT ACCURACY (PEA) The transmitter associated with this loop is in direct contact with the process. There is no primary measurement element such as a flow orifice. Hence, PEA is not included in the transmitter error evaluation. Therefore: PEA =O

Per Input 4.9.2, the Analytical Limit (AL) is 825 PSIG.

DEPT/DIV CALCULATION NO. IP-C-0067 REVISION: I SHEET C/NSED 33 of 39 8.2 CALCULATION OF THE NOMINAL TRIP SETPOINT (NTSP) As defined in Section 3.2, the As-Found Tolerance (AFTL) term will be replaced with the calculated 915-day Drift (DTIc). The Nominal Trip Setpoint (NTSP) should be calculated using the equations below depending on the direction of process variable change when approaching the Analytical Limit. From 7.3.4, trip setpoint for an increasing process is calculated as follows. NTSP(INc) =AV -DTIc For process variables that decrease to trip. NTSP(DEC) = AV + DTIc Therefore, the trip setpoint (NTSP) of the IB21N076A-D and IB21N676A-D loops is: NTSP(DEC) = AV + DTIc Where: AV = 841 PSIG Section 8.1 DTIc = 5 PSIG Section 8.3.3 Substituting, NTSP = 841 + 5 PSIG
= 846 PSIG Therefore, for decresing setpoint, NTSP 2 846 PSIG (2a)
Per Section 7.5.1, the field calibrated setpoint values are 858 PSIG (for ATM B21N676A and D) and 861 PSIG (for ATM B21N676B and C). Head corrections (Attachment I) of 9 PSIG (for ATM B21N676A and D) and 12 PSIG (for ATM B21N676B and C) are included in these values. Therefore, the field calibrated setpoint without the head corrections is 849 PSIG. The field calibrated setpoint value is conservative to the calculated NTSP and should be retained. Therefore, ForATM's B21N676A to D (without head correction) NTSP = 849 PSIG (2a) ForA TM's B21N676A and D (with head correction) NTSP = 858 PSIG (20) ForATM's B21N676B and C (withi head correction) NTSP = 861 PSIG (2a)

As defined in NES-EIC-20.04, Appendix J (Reference 6.8), when formal Drift Analyses have been performed, the calculated 915-day Drift (DTIc) may replace the VAL, DL and CL variables collectively in the equations. The Loop Calibration Error (CL), Loop Drift (DL) and As-Found Tolerance (AFT) are calculated for comparison purposes only. From Section 7.3.6, the device As-Found Tolerance will be determined as follows: AFTi =+(N\(ALT1 ) ++) .n) 1 (2a) nn n Where: ALTi = device's As-Left Tolerance Di = device's drift value Ci = errors of M&TE used to calibrate the device The loop As-Found Tolerance (AFT) tvill be calculated as follows: AFTL = +(N) (>) +(P.LJ (2(s) Where: DL = Loop devices' drift value, as defined in Section 7.3.3 CL = Loop devices' calibration effect, as defined in Section 7.3.2 8.3.1 As-Found Tolerance (AFTpT) for Transmitters IB21N076A-D From above: Calibrated Span = 1200 PSIG Section 7.4.1 ALTPT = +/- 0.250% span (2a) Section 7.5.1 DPT = +/- 0.50% span (20) Section 7.6.1 CPT =+/- 0.1268% span (3a) Section 7.5.2.1

IP-C-0067 REVISION: I SHEET C/NSED 36of39 8.3.3 As-Found Tolerance (AFTL) for the IB2 IN076A-D and I B21N676A-D Loop From Section 7.3;6, the loop As-Found Tolerance (AFT) will be calculated as follows: AFTL =+(N) (cj +( ) From above: Calibrated Span = 1200 PSIG Section 7.4.1 DL = +/- 8.3967 PSIG (2a) Section 7.6.3 CL = +/- 4.0525 PSIG (2a) Section 7.5.4 Substituting: AFTj = +(2)j( 2 + ( 2 AFTL = +/- 9.3235 PSIG (2a) Per Ref. 6.1, AFT is rounded to the procedure precision. Therefore: AFTL = +/- 9 PSIG (2a) As defined in Section 3.2, the As-Found Tolerance (AFTL) term will be replaced with the calculated 915-day Drift (DTIc). From Reference 6.6, the 915-day (30-month) drift value (DTIc) for the Main Steam Line Pressure - Low loops was calculated to be: DTIc =+ 0.342 % Span, with a bias drift of +/- 0.00 % span (2a)

- 1200 PSIG
= +/- 4.104 PSIG This value is rounded up to the next higher value. By rounding up the DTIC value, the calculation of nominal setpoint is made more conservative, as shown in Section 8.2. Therefore:.
DTlc = +/- 5.00 PSIG (2a)
DEPT/DIV CALCULATION NO. IP-C-0067 REVISION: I SHEET C/NSED 37 of 39 Since the calculated AFTL is greater than the calculated 915-day Drift value (DTIc), the calculated 915-day Drift value (DTIc) will be utilized for the AFT. Per Reference. 6.1, the AFT is rounded to the precision of the procedure. Therefore:, AFTL = +/- 5.00 PSIG (2a) 8.4 CALCULATION OF RESET VALUES The trip reset value is selected to prevent overlap with the acceptable NTSP tolerance band, and also to prevent interference with normal plant operations. The minimum reset value is calculated as follows for the Main Steam Line Pressure - Low function: Reset 2 NTSP + AFTL 2 846 + 5 PSIG 2 851 PSIG Per Inputs 4.2.2, 4.2.3, 4.3.4 and 4.2.5, the existing reset value is 894 PSIG (for ATM's B21N676A and D) and 897 PSIG (for ATM's B21N676B and C), which are 36 PSIG above the NTSP of 858 and 861 PSIG (Section 8.2), respectively. Head corrections (Attachment 1) of 9 PSIG (for ATM B21N676A and D) and 12 PSIG (for ATM B21N676B and C) are included in these values. Therefore, the field calibrated reset point without the head corrections is 885 PSIG. The minimum reset values derived from AFTL is 851 PSIG, the existing reset values are greater and are conservative. Therefore, ForATM's B21N676A to D (without head correction) Reset = 885 PSIG For ATM's B21N676A andD (with head correction) Reset = 894 PSIG ForATM's B21N676B and C (with head correction) Reset = 897 PSIG

9.0 CONCLUSION
S This calculation determined that the existing ORM setpoint is conservative with respect to the calculated NTSP value. Therefore, the existing ORM setpoint may be retained. Note that the ORM setpoint is 2 849 PSIG (Output 5.8). ForATM's B21N676A to D (without head correction) NTSP = 849 PSIG (2a) ForA TM's B21N676A and D (with head correction) NTSP = 858 PS1G (2cr) ForATM's B21N676B and C (wvith head correction) NTSP = 861 PSIG (2a) This calculation determined the Technical Specification Allowable Value (837 PSIG per Reference 6.3.2) is not conservative with respect to the calculated Allowable Value and should be revised. AN' > 841 PSIG (2 a) Section 8.1 This calculation also determined the As-Found Tolerance (AFTL) and As-Left Tolerance (ALTL) in the calibration procedures (Outputs 5.1 to 5.5) for total loop calibration should be revised: AFTL = +/- 5.00 PSIG (2a) Section 8.3.3 ALTL = +/- 4.00 PSIG (2 cy) Section 7.5.1 See Figure 1 for graphical presentation of the relationships of AV, NTSP, ALT and AFT.

A review of the Steam Tables (Ref. 6.8) determined the change in condensate specific volume, between the maximum and minimum environmental limits, results in a head correction variation of approximately 0.1 PSI. Therefore, due to the minimal impact of the head variations, this analysis will utilize the median ambient Turbine Building temperature of 86 0 F (IB21N076A,D) and 940 F (IB213N076B,C) to determine the specific volume of the condensate in the Main Steam Line Pressure -Low transmitter sense lines.
"SVI" and "SV2" are the specific volumes of water in the instrument sensing lines based on Main Steam Line normal operating pressure (1 025 PSIG) and Turbine Building temperature (86 0 F and 940 F). The specific volumes of water at 860 F and 1025 PSIG and 947F and 1025 PSIG are obtained by interpolating information found in Steam Tables (Ref. 6.8). Since 1025 PSIG is approximately 1040 PSIA (1025 PSIG + 14.7 PSI = 1039.7 PSIA), from Steam Tables for Superheated Steam and Compressed Water (Ref. 6.8);

Therefore, interpolating for the volume at 86°F:

Thus, when the main steam line pressure is actually 0, the IB21N076A,D transmitters will "see" 9 PSIG of head, and the IB21N076B,C transmitters will "see" 12 PSIG of head. Similarly, when the actual main steam line pressure reaches the upper span of 1200 PSIG, the IB21N076A,D transmitters will "see" 1209 PSIG of head, and the IB21N076B,C transmitters will "see" 1212 PSIG of head.

- This report documents thQ testing that vas performed to demonstrate the now stability Specification of +/-0.2% URL for 30 months for Rosemount Model 1152, 1153 and 1154 transiltterz. The former specification of +/-0.25%URL for 6 months, including accuracy, was based on test results from the Model 1151 (Ref. 2.1). The now 5pacificiatlon

.e
.I ?ZGS DZSCRXPTZOX Test units consisted of four 1153 Series 8 transmitters, model number 11S3GB6PA and serial numbers 402720, 402721, 402722, 402723, all calibrated 0 to 100 psig.. The transmitters vere powered vith 34 V and output voltage of the transmittar vas measured over a 5oo ohm resistor.
Response of the transmitter to an input pressure of S0
-r- _ a P 5 psi w recorded daily for the fi tveX A-the
'weekly for the next si months, and iitonty for Ire duration of the test. Ambient temperature was also n* recorded. Calibration checks at 20% span increments were made between 0 and 100% span at the beginning and end of the test.
The test was originally scheduled to run 18 months. Input pressure was removed after 18 months and a calibration'check performed. A request was made to extend the test out to 30 .months-so another calibration check vas pcmformed prior to pressurizing the transwitters to 50 psi again. No adjustment was made to the calibrations of the test units during the test interruption, Calibration data was recorded again after the test was over. ROSEMOU1NT REPORT D8900126 FACE I

*Jr#-16-2001 10:23 ROSE2JViNT FXLEAR b l r.w Transmitter output voltages measured during the first 18 months of the test are shown in Table 1 along with the output shifts. Output shifts are referenced to the output voltage measured at the beginning of the test.
All of the output shifts are vithin the new stability specification of +/-0.2% URL (E'.016 V) . Ambient temperatures ranged from 70 to 8Z°F Resalts from the extension of the test to 30 months are shown in Table 2. Output abhits agailT ar- referenced to the output voltage measured at the beginning of the test. Eowover, the shifts are adjusted for the change in output observed between the last neasurement before the extension and the first measurement of the extension due to shut-down and start-up of pressure source. For example, the output measured after 18 months for 8/N 402720 was 5.990 V. After the pressure source was
. - reapplied to the transmitter, the output was 5.996 V.
... The output.shift referenced to'the beginning or the test is 40.006 V (5.996 - 5.990 V). To determine the output shift due to drift, this value is adjusted by subtracting the 0.006 V output shift due to the change in pressure, resulting in an output drift of 0.000 V (0.006 - 0.006V),.
all of the output shifts in Table 2 are within the new stability specification of +/-0.2* URL (+/-.016 V) A graph of the output drift is shown in Figure 1. Ambient temperature ranged from 67-760&. The calibration checks sade at the beginning of the test are shown in Table 3 and meot the accuracy specification
+0.25% span (+/-0.020 V). Calibration checX3 made after 18 months are shown in Table 4, prior to the extension to 30 months in Table 5, and after 30 months in Table 6. All meet the combined effects of accuracy (+/-0.25% span) and drift (+/-0.2% MML) -

Clinton SVC Project
- 1. SVC BACKGROUND Illinois Power Company commissioned ABB Electric Systems Technology Institute (ABB ETI) to perform a sizing study for the Static Var Compensator Systems at the Clinton Power Station.
Illinois Power Company anticipates that the 345 kV and 138 kV system strengths will decrease in the future due to the deregulation of the electric power transmis-sion system. By year 2007, it is estimated that the 345 kV system voltage can drop as much as 11% on loss of the Clinton Power Station. Similarly the 138 kV system voltage can drop as much as 16%. Furthermore, under certain low load conditions, it is anticipated that the 345 kV and 138 kV systems can have system overvoltages as high as 6% over nominal. When the Clinton Power Station goes off-line due to a protective trip, a number of large 4160 Volt pumps are required to start-up to provide additional cooling of the nuclear system. The Clinton SVC sizing study, ABB Report No. 97-301 9-75-R-1, addresses the worst case conditions based on the information provided by Illinois Power Com-pany and as a result it was determined that two (2) SVCs, one for each 4160 Volt system, will be required to dynamically compensate for;
- 1. 4160 voltage drop Slue to the loss of Clinton Power Station
- 2. Additional 4160 voltage drop due to the start-up of large cooling pumps
- 3. Voltage increase for certain conditions, e.g., light load In addition to the above listed requirements, there were a number of constraints imposed on the SVC systems:
- 1. Available site area for the SVC, especially the RAT SVC, is limited
- 2. SVC MVAR size is limited to the capability of available circuit breakers
- 3. Generation of harmonic currents on the 4160 Volt busses shall be limited.
Based on the requirements and constraints outlined above, it was determined that two (2) identical SVCs, one for each 4160 Volt system, should be installed. The size for each SVC shall be 28.5 MVAR capacitive and 14 MVAR inductive to dynamically compensate for all expected under- and over-voltage conditions. Illinois Power Company further decided to replace the existing Reserve Auxiliary Transformer (RAT) and Emergency Reserve Auxiliary Transformer (ERAT) with new larger units with On-Load Tap Changers (LTC) in the primary windings. The LTCs compensate for all steady-state undervoltage changes while maintaining the dynamic capacitive range of the SVCs for any dynamic changes in the 345 kV and 138 kV systems, as well as on.the 4160 Volt busses. The SVCs normally operate steady-state in the lower inductive range, typically 0 - 7 MVAR inductive, but will compensate for all dynamic voltage variations. SVC operation outside the lower inductive range for extended periods, typically 2 -5 minutes, will initiate tap changer movement to return the SVCs to this range.

- 2. SVC SYSTEM DESIGN Two (2) identical Static Var Compensators (SVCs), rated +28.5/ -14.0 MVAR each, are supplied for the Clinton Power Station to provide voltage support for the 4160 Volt auxiliary power systems as follows:
Reserve Auxiliary Transformer (RAT) system. The RAT has two secondary windings, 6.9 kV and 4160 Volt. The RAT SVC provides direct voltage sup-port to the 4160 Volt system only. It is not presently designed to support the 6.9 kV system. However, when Illinois Power Company proceeds with the installation of a new RAT with On-Load Tap Changers, then a LTC control function will be enabled in the SVC control that will monitor both the 6.9 kV system voltage and the MVAR flow between the SVC and the 4160 Volt sys-tems. The SVC control will allow the LTC to step up or down to maintain steady-state control of the 4160 Volt bus while the 6.9 kV bus voltage remains within acceptable limits. The 6.9 kV operating voltage limits remain to be determined.
- Emergency Reserve Auxiliary Transformer (ERAT) system. The ERAT SVC provides direct voltage support to the 4160 Volt system. Upon installation of the new ERAT with LTC, the SVC control will monitor the MVAR flow between the SVC and the 4160 Volt bus. It will initiate LTC steps up or down to main-tain the steady-state control.
Each of the two SVC Systems is composed of the following main parts:
- one Thyristor Controlled Reactor (TCR) bank, rated 21.5 MVAR
- one Thyristor Switched Capacitor (TSC) bank, rated 21.0 MVAR
- one 5 and 7t/1/HP Harmonic Filter bank rated 7.5 MVAR
- two series connected Main Breakers, SF6 dead-tank PM type, rated 145 kV, 4000 A, 63 kA
. one Disconnect Switch for the Main Bus
- one Disconnect Switch for each TCR, TSC, and Filter Bank
- one lot of Instrument Transformers, CT's and Prs, for Control, Protection and Metering The attached appendix contains both Single-Line Diagrams and Protection Single-Line Diagrams, as well as a list of the Scope of Supply, for both the RAT and ERAT SVC Systems The RAT and ERAT SVCs are connected to the existing 4160 Volt auxiliary power busses. Each SVC can be continuously controlled in a 'dvnamic ranae from 14 MVAR Inductive to 28.5 MVAR capacitive, with the reactive power defined at 1.0 pu, 4160 Volts, reference voltage.

System Description
Clinton SVC Project 2.1 Normal Voltage Control Operation Once the new RAT and ERAT units with LTCs are installed, the steady-state volt-age of the 4160 Volt bus is maintained by transformer Load Tap Changer (LTC) operation while any dynamic voltage variations are minimized by SVC operation. The SVC normally maintains operation in the lower inductive range, typically 0 - 7 MVAR inductive, in order for the SVC to retain its full capacitive range in reserve to counteract large system voltage drops and/or motor starting. Inthe interim period, i.e., SVC operation with the existing RAT and ERAT units without LTCs, the LTC automatic control function in the SVC control system is disabled. The SVC for the RAT will be fully operational and will maintain the volt-age control of the 4160 Volt system. The SVC sizing studies show that the RAT SVC will always reduce the load on the existing RAT when it is heavily loaded, even with full capacitive MVAR output from the RAT SVC. On the other hand, the existing ERAT, due to its lower rating, may become over-loaded at full capacitive output from the ERAT SVC. The ERAT SVC control and protection system will therefore include an interim overload protection, both in the PHSC system and in the redundant DPU-2000R protections, that matches the thermal overload characteristics of the existing ERAT unit. Upon installation of the new ERAT with LTC, the overload protection will be reset to match the SVC characteristics and at the same time the LTC control function will be enabled in the SVC control system. The Filter Bank is always connected to the 4160 Volt bus whenever the SVC is connected to the 4160 Volt bus. The filter bank provides a capacitive 7.5 MVAR supply. Therefore the Thyristor Controlled Reactor (TCR) Bank is normally oper-ating in its 7.5-14.5 MVAR range to counteract the filter bank capacitive supply while maintaining the overall SVC operation in the lower inductive range in steady-state operation; The 4160 Volt bus steady-state voltage is normally maintained by Load Tap Changer operation, and the LTC is controlled by the SVC control system. Ifthe SVC operates outside its normal steady-state range, typically 0 - 7 MVAR induc-tive, for a period of time, typically 2-5 minutes, the SVC control will send an order to the LTC to step either up or down to bring the SVC back to its normal steady-state operating range. The intention Is to always ensure sufficient capacitive dynamic SVC range for any potential event that may occur, even at over-voltage operation. The LTC control logic in the SVC control is therefore equipped with afeedback function that moni-tors the actual transformer tap position. Upon detection that the SVC control should issue an order to step the LTC above the maximum allowed tap position for maintaining the full capacitive dynamic range in all circumstances, the order will not be allowed to pass through. In the ERAT case the SVC control is not allowed to issue an order to step the LTC above the 4R tap position, i.e., the nominal ERAT rating position. In the RAT case the maximum allowable tap posi-tion is not yet determined. In case of.a large voltage drop on the 4160 Volt bus, e.g., due to loss of genera-tion at the Clinton Power Station followed by start of several large pumps, the SVC will operate at full capacitive output, 28.5 MVAR. The SVC control will in this case send rapid step orders to the LTC, typically a step every 3 - 4 seconds, to bring the SVC operation back into the dynamic range and away from its capacitive limit.

System Description
Clinton SVC Project 2.2 Back-Up LTC Voltage Control Operation As indicated previously, the LTC is under normal conditions controlled by the SVC control system. If for any reason the SVC is not available, due to SVC failure, open main circuit breakers, open main disconnect switch, etc., then the LTC auto-matically switches over to the back-up voltage control mode. This back-up, or direct, voltage control is provided by a standard LTC voltage control unit that is physically located in the LTC control compartment on the new RAT and ERAT units. It senses the voltage and load on the 4160 Volt bus from a dedicated potential transformer and a bushing current transformer, both located on the A-phase on the low-voltage side of the transformer. The voltage on the 4160 Volt bus is thus maintained per the settings in the LTC voltage control unit. When the SVC becomes available for operation again it will regain control of the LTC and disable the back-up voltage control. 2.3 SVC "Freeze" Output Functions There are three (3) diesel generators at the Clinton Power Station for back-up 4160 Volt supply in case both the 345 kV and the 138 kV systems are faulty or de-energized. These diesel generators are connected to the 4160 Volt busses through switchgear breakers. The diesel generators are required, and designed, to connect to the 4160 Volt auxiliary power busses in response to safety signals. The units are tested on a regular basis, typically once every month. When any of the diesel generator breakers, or synchronization switches, close due to testing or operation, signals are sent to the SVC control to "freeze' the MVAR output. At completion of the test, or return to normal feed, the diesel generator breaker, or synchronization switches, will open and the SVC control will release the "freeze' and return to its normal mode of operation. There are concerns that must be taken into account when initiating a SVC "freeze" action due to diesel generator operation. The three diesel generators are tested on a regular basis; each unit is tested at least once every month. Each diesel generator test takes approximately one (1) hour to complete. As a result the SVC operation is "frozen", i.e., disabled, approximately three (3) hours every month. There is always a certain change that something can occur in that time frame that would normally require significant action by the SVC. The SVC controls are as much as 50 times faster than the diesel generator exciter. The SVC should therefore be capable of remaining in normal operation, with the diesel generator in service on the same 4160 Volt bus, without interfering with the performance of the diesel generator exciter. The SVC will maintain the voltage on the bus by varying its MVAR contribution and the diesel generator will generate or consume MVAR as the power factor operation is changed to be leading or lagging. It may therefore be possible to operate the SVC with the diesel generator in service without "freeze" of the MVAR output. Illinois Power Company may allow this mode of operation upon completion of adequate testing. Typically, the RAT carries the auxiliary system load before the ERAT is loaded. The 4160 Volt load busses for the RAT and ERAT systems are separated by a transfer breaker. If the 4160 Volt loads must be transferred between the RAT and the ERAT, the transfer breaker will close while both busses are energized, i.e., so called 'hot' transfer. This transfer operation is carried out by manual operator actions and is typically completed within five (5) seconds. Page 6 98-02-25 Rev. 0

System Description
Clinton SVC Project Indications are sent to both the RAT SVC and the ERAT SVC to 'freeze" the MVAR output during this 'hot" transfer by breaker monitoring status, i.e., when all breakers are closed, the indications go through. Since both SVC are paralleled during the "hot" transfer the operating point for the SVCs is not clearly defined. In this brief interval, the MVAR output from both the RAT and ERAT SVCs should therefore be 'frozen". Upon completion of the "hotr transfer the indications will disappear and the SVCs will resume their normal operation. In a similar fashion, an indication is sent to the RAT SVC to "freeze" the MVAR output during 'hot' transfer, i.e., parallel operation, between the UAT and the RAT. There is very little concern that anything will occur that will require significant SVC action during the "hot" transfer "freeze" interval. The "hot" transfers do not occur on a regular basis, and when they do the "freeze' time is typically less than 5 sec-onds. 2.4 SVC Performance Requirements Each SVC System is designed to meet the following conditions: Rated connection voltage 4160 (1.00 pu) Volts

Clinton SVC Project 2.5 SVC Equipment Design Considerations 2.5.1 Thyristor Controlled Reactor (TCR) Bank Each TCR bank is rated 21.5 MVAR. Since the TCR bank is continuously con-trolled from 0 to full inductive output, 21.5 MVAR, by varying the firing angle of the associated thyristor valve a certain amount of odd harmonic currents are gener-ated, please see graph below. 1MO Harmonic G M Current go - r m (A Amplitude AM / r (11 (A)
~~~-1s/_r (1aX (P
-anO TCR Firing Angle The TCR is a three-phase bank connected in a delta configuration. The triplen harmonic currents, or harmonics of zero sequence characteristic, i.e., 3d, el, 15',
etc., are therefore not detectable outside the TCR bank in a balanced system. The 5th and 7 th / HP filter bank, rated 7.5 MVAR capacitive, shall always be con-nected in order to minimize the harmonic content due to the TCR operation. This gives a net capability of 14 MVAR inductive for voltage regulation. The rating Is referred to 1.0 pu system voltage. In large transmission system applications, the air core reactors in the TCR bank are typically split in two halves, one half on either side of the thyristor valve. There are two main reasons for this arrangement; reduced size and weight of each reactor, and somewhat reduced dv/dt stresses on the thyristors. The air core reactors in the TCR bank for the Clinton SVC Project are not suffi-ciently large or heavy to justify a split in two halves. The dv/dt stresses on the thy-ristors are not severe in this application and the thyristor technology has improved to the point where the thyristors can withstand considerable higher levels of dv/dt. The TCR bank is designed for continuous operation at system voltages up to 1.1 pu voltage. A current limiting control function protects the TCR bank against thermal overload. The protective function is described later in this system description. The protec-tive settings and time delays are defined in the Protection Coordination Report. 98-02-25 Rev. 0 Page 8

Clinton SVC Project 2.5.2 Thyristor Switched Capacitor (TSC) Bank The capacitor.stacks in the TSC bank are of the "Open" stack type, made up of capacitor units connected in series and parallel to obtain the required MVAR rat-ing. The capacitors are of film design with non-PCB dielectric fluid, or impregnate. The capacitors are intemally fused, and have built-in discharge resistors. The TSC bank is rated 21.0 MVAR capacitive. The TSC bank is either continu-ously"ON" or continuously'OFF'. Therefore there is no generation of harmonic currents. The TSC is a three-phase bank connected in a delta configuration By using a thyristor valve, instead of circuit breaker, for switching the TSC bank in and out, the time lag for switching is insignificant. Further, by remembering the point, i.e., positive or negative voltage, where the TSC bank was switched out there is no capacitor discharge waiting time before the TSC bank can be switched in again. The thyristor valve control will switch in the TSC bank at the same volt-age polarity as it was switched out. When a capacitor bank is connected to a system a large current surge occurs. This current surge could potentially damage a thyristor valve if it was undamped. To prevent this, a small reactor is always placed in series with the thyristor valve and the capacitor bank. This reactor is typically tuned to the 4.51h harmonic fre-quency. To further prevent the current surge through the thyristor valve from becoming too large, the thyristors are only fired at voltage zero crossings. This provides almost transient-free switching which saves the thyristors. However, this also prevents the continuous control of the TSC banks. The capacitors in each phase of the TSC bank are configured in a double SH' arrangement. See the figure below. 3-Irn-I 3-H- [I Each leg contains three (3) capacitor units for a total of 24 units per phase. The reason for this double UH' arrangement, rather than a single 'H", is that the energy dissipation from each leg would be excessive in case of a short circuit if each leg would contain six (6) capacitor units. During the installation and commissioning process of the TSC bank the capacitor units are balanced such that the current through the current transformer in the center connection of each 'H' arrangement is at, or very close to, zero current. If any capacitor unit develops an internal failure, the capacitance will change in that leg and there will be a shift in current distribution between the legs in the 'H'. This causes an unbalance current in the center connection. Depending on the ampli-tude of this unbalance current, an alarm or a time delayed trip action will be trig-gered. 98-02-25 . Rev. 0 Page 9

System Description
Clinton SVC Project A current limiting control function protects the TSC bank against thermal overload. The protective function is described later in this system description. The protec-tive settings and time delays are defined in the Protection Coordination Report. 2.5.3 Filter Bank The filter bank is divided into two branches, one single-tuned 5 h harmonic branch and one broader-tuned 7h harmonic / High-Pass branch. This arrangement allows the filter bank to suppress the harmonics generated by the six-pulse opera-tion of the TCR and minimize possible resonance with the rest of the system. The filter rating and tuning is discussed in the Harmonic Analysis Study, ABB ETI Report No. 97-0219-30. Each filter branch is rated approximately 3.75 MVAR, for a filter bank total of 7.5 MVAR, referred to 1.0 pu system voltage. The capacitor stacks in the filter branches are of the enclosed 'SIKAP" design type, made up of capacitor units connected in series and parallel to obtain the required MVAR rating. The capacitors are of film design and have non-PCB di-electric fluid, or impregnate. The capacitors are internally fused, and have built-in discharge resistors. Each filter branch is connected in a double un-grounded "Y configuration, i.e., each phase is divided into two legs, see figure below. During the installation and commissioning process of the filter branches, the capacitor units are balanced such that the current through the current transformer in the neutral connection is at, or very close to, zero current. If any capacitor unit develops an internal failure, the capacitance will change in that leg and there will be a shift in current distribution between the legs, causing an unbalance current in the neutral connection. Depending on the amplitude of this unbalance current, an alarm or a time delayed trip action will be triggered. Each filter branch is protected against thermal overload. The protective function is described later in this system description. The protective settings and time delays are defined in the Protection Coordination Report. The broader-tuned 7h harmonic / High-Pass branch contains a resistor in parallel with the filter reactor for each phase. These resistors have separate CTs for monitoring resistor overload as well as an open circuit. The protective function is described later in this system description. The protective settings and time delays are defined in the Protection Coordination Report. 98-02-25 Rev. 0 Page 10

System Description
Clinton SVC Project 2.5.4 Thyristor Valves The thyristor valve for the TCR bank is a standard Veristack TCR type valve, which is indirectly light-triggered. It is made up of series connected thyristors in anti-parallel, four (4) thyristors in series per phase. The thyristors are 4 inch in diameter and have a maximum continuous current of 2,000 Amps. The thyristor valve for the TSC bank is a standard TSC type valve, which is indi-rectly light-triggered. It is made up of series connected thyristors in anti-parallel, six (6) thyristors in series per phase. The thyristors are 4 inch in diameter and have a maximurmi continuous current of 2,000 Amps. Firing pulses for the thyristors are sent from the SVC control, PHSC system, and the associated valve base electronic units via fiber optic links to the thyristor elec-tronic units on thyristor potential level. These units then convert the light signal to electric pulses that are used to trigger the thyristors. The thyristor valves are water cooled. Approximately 95 % of the heat losses from the thyristor valves are dissipated through the water cooling system. The remaining 5 % of heat losses are dissipated into the surrounding air. The TCR thyristor valve is protected against overvoltage by a forward protection, break-over diode (BOD) on each thyristor level. The BOD will cause the thyristor electronic unit to trigger the associated thyristor when a substantial overvoltage is detected across the thyristor. The TSC thyristor valve is protected against overvoltage by means of surge arresters connected across the valve. 2.5.5 Thyristor Valve Cooling The valve cooling system for each SVC is a standard system consisting ol a com-bined pump / treatment skid with built-in control system and outdoor cooling tow-ers and piping. It also has measuring instrumentation for cooling media flow, temperature, pressure, level, and conductivity. See the Cooling System Flow Diagram, drawing no. 3-6249-001 The valve cooling system is a 'closed" system. The cooling media is a mixture of deionized water and glycol. The media is circulated through the outdoor cooling towers (or bypass shunt), the pump I treatment skid, and the thyristor valves. The cooling tower consists of radiators which allow cooling of the media without contact with the open air. The outdoor cooling tower has three (3) cooling fans. Two are for normal operation and one of them is a redundant unit. The valve cooling pipes are made of stainless steel, except for the cooling pipes
- in the thyristor valve assembly where plastic type FEP pipes are used.
The two (2) pumps are fully redundant. One is in normal operation and one is in standby mode. The redundant pump installation allows for testing and on-line maintenance. The pumps are automatically switched at regular intervals, typically one week, in order to equalize the pump operating times. In case of pump failure, detected by loss of pressure or cooling media flow, the pump shift is automatic, i.e., the standby pump is started automatically and the normal pump is de-ener-gized.

System Description
Clinton SVC Project The thyristor valve cooling system is always kept in operation, that is, the water / glycol media is always flowing, independent of mode of thyristor valve operation. The valve cooling control continuously monitors the media temperature. When it drops below a certain temperature, typically 750 F (240 C), the outdoor cooling tower is automatically bypassed by two (2) mechanically linked valves which direct the cooling media through a shunt pipe on the pump unit. As the temperature increases the control will adjust the position of the valves to gradually decrease the flow through the shunt and increase the flow through the outdoor cooling tower. Further increases in media temperature will cause full flow through the cooling tower. The valve cooling control will start the cooling fans, one at the time, as the media temperature increases above a reference temperature, typically 104° F (40° C). The media temperature and flow are continuously monitored. Alarm and trip signals are generated for high temperatures and for low media flow. Approximately 90 - 95% of the water / glycol mix circulate through the main loop, including the TCR and TSC thyristor valves. The remaining 5 - 10% of the media circulate through the water treatment plant, where it is deionized and de-oxygen-ated. The cooling media conductivity is monitored continuously. Alarm and trip signals are generated for high conductivity. The pump / treatment skid contains the expansion vessel, a pressurized stainless steel tank, which maintains the cooling media pressure in the entire valve cooling system, typically 7.2 psi (50 kPa), while allowing for expansion and contraction of the water / glycol media due to temperature changes. The system pressure and the expansion vessel media level are continuously monitored. Alarm is generated for low media level. Alarm and trip signals are generated for high and low pres-sure. All alarm and trip set points for the thyristor valve cooling system are included in the Cooling System Set Point List, document no. 8-6249-230.
.2.5.6 SVC Main Breakers The redundant main circuit breakers are 145 kV SF6 dead-tank power circuit breakers, type PM, manufactured in ABB's Greensburg facility. The units are rated for 4,000 A /63 kA. The reason for the high voltage rating for this specific application is that this is the smallest standard type breaker that can handle a continuous load current of 4,000 Amps while at the same time interrupt a fault cur-rent in excess of 49 kA with sufficient margin. The 145 kV circuit breakers are standard type dead-tank breakers with built-in bushing type current transformers.
The circuit breakers are redundant to allow for breaker failure with minimum effect on the RAT and ERAT systems in normal operation. Page 12 98-02-25 98-02-25 Rev. 0 Rev. 0 Page 12

System Description
Clinton SVC Project 2.5.7 Auxiliary Power Supply Design The auxiliary power supplies for the SVC systems are redundant in most aspects. There are two (2) 480 V, three-phase supplies, for each SVC system. One 480 V supply from the station service system in the main plant and one 480 V supply from a dedicated 4,160 /480 V, 75 kVA, auxiliary power transformer on the SVC main bus. Additionally, there are two (2) 48 V DC sources that are fully independ-ent of each other. Each DC system contains one (1) battery charger, one (1) 48 V battery, and one DC distribution panel. Means are provided so that Illinois Power Company in the future can connect the two DC sources together through an auctioneering diode arrangement for increased redundancy. The reason being that in case of failure of a battery charger or a battery, the other source can carry its own DC load as well as the DC load for the faulty system via this auctioneering diode arrangement. 2.6 SVC Control System It is essential that the thyristor valves be controlled by a fast control system. The Programmable High Speed Controller (PHSC), an ABB microprocessor based control system, is specifically developed for fast and efficient control and monitor-ing of systems such as the SVC applications. The basic SVC control principle is voltage control based on the positive sequence voltage response, measured on the main SVC bus. The PHSC system contains three (3) processor boards; Two (2) processor boards are used for the SVC process control, protection and monitoring. One (1) proces-sor board is dedicated to fault recording. In addition, there are a number of ana-log and digital I/O boards making up the PHSC system. Since the overall control of the system includes the control function for the future RAT and ERAT Load Tap Changers (LTCs), this special LTC control function is included in the PHSC software package. This control function was described in section 2.1 "Normal Voltage Control Operation". 2.7 SVC Operation and Monitoring Even though the SVC system may be fairly complex, it is relatively easy to oper-ate, and to monitor its performance. The SVC control system panel comes equipped with a mimic board for operator control and monitoring. This mimic board contains a mosaic layout of the SVC, i.e., a single line representation, a number of analog meters, indications of breaker, disconnect switch and grounding switch status, a number of push button controls, and numerous alarm and trip LEDs. Analog meters display the following information:
- Total SVC MVAR Generation / Consumption
- Measured SVC Bus Voltage
- Measured Current in the TCR Bank
- Measured Current in the TSC Bank 98-02-25 Rev. 0 Page 13

System Description
Clinton SVC Project The symbols for the disconnect and grounding switches and the main breakers contain LEDs for status indication. The Red LEDs of each symbol are lit to indi-cate 'Closed" position, and the Green LEDs are lit to indicate 'OpenS position of the associated switches or breakers. It should be noted that all disconnect and grounding switches are manually operated. Push buttons on the mimic perform the following operations:
- EON. Starts the SVC in controlled manner. The logic first verifies that voltage is established on the main 4160 V bus, the PHSC control system is operating, the valve cooling system is operating, and that no trip or major alarm conditions exist. The control logic then closes the main circuit breaker to energize the SVC bus as well as the harmonic filter bank. This also enables the TCR bank to operate to counteract the capacitive MVAR genera-tion from the harmonic filter bank and to respond to the PHSC demand for' reactive power to support the 4160 V system. The 'ON" command also directs the SVC control to disable the Load Tap Changer (LTC) back-up volt-age control and to assume SVC control of the LTC.
.OFF" Stops the SVC in a controlled manner. It disables the SVC con-trol of the LTC and enables the LTC back-up voltage control. Simultaneously the thyristor valve control ramps the TSC and TCR banks to zero MVAR out-put and then blocks the thyristor firing pulses. As soon as the firing pulses are blocked, the control logic sends a trip order to the main breaker.
* 'ESOFF" (Emergency Shut Off) This is an emergency shutoff which bypasses the PHSC SVC control and sends a trip signal directly to the main circuit breaker.
- OSEL" Select button for the analog voltmeter. It allows the operator to check phase-to-phase and phase-to-ground voltages on all three phases.
- OR" Reset button for the alarm anid trip indication panel.
* "Li Lamp test The mimic contains 12 "Red" LEDs for trip information and 12 'Yellow" LEDs for alarm indication. The alarms and trips are confirmed and then reset by the OR' reset button.
The trip and alarm indications on the mimic panel remain to be determined. They are programmable from the PHSC system. In many cases an alarm indication will represent a group alarm, e.g., a problem in the 48 V DC system, or an alarm con-dition in the thyristor valve cooling system. The trip and alarm indications are defined in the 'SVC Operating Instruction" manual. Means are provided to start or stop the RAT and ERAT SVCs from the plant con-trol room by the 'ON" and "OFF" control. Indications are also provided to the plant control room to indicate "Ready",
"Alarm", and "Trip" status for the RAT and ERAT SVCs. Provisions are also made to monitor the main circuit breaker status, "Open" or "Close", as well as the breaker trip coil status.

- 3. HARMONIC ANALYSIS The harmonic analysis considers the following factors:
. The behavior of the system due to injection of harmonic currents, i.e., the system impedance relative to harmonic current generation.
- The harmonic generation sources, i.e., the Thyristor Controlled Reactor (TCR).
- The potential for resonance between the system and the SVC branches.
3.1 Network Harmonic Characteristics Since the harmonic impedance of the 138 kV and 345 kV systems were not known, a range of severe impedances was investigated for each system. Each of these ranges was scanned by injecting one (1) ampere at each harmonic to determine the impedance that resulted in the highest harmonic voltages and cur-rents. 3.2 Harmonic Generation Sources 3.2.1 TCR Harmonic Generation The TCR generates odd harmonics depending on the actual triggering angle for the thyristor valve, please see graph under section 2.2.1 "Thyristor Controlled Reactor (TCR) Bank". For a symmetrically controlled TCR, due to ith delta con-nection, most harmonics of zero sequence characteristics, i.e., triplen harmonics, will be trapped within the TCR bank and will not be seen on the SVC bus or the 4160 V bus. 3.2.2 Network Negative Sequence Voltage For performance calculations, a system negative sequence voltage of 2.5 % was considered. Calculations show that for a 21.5 MVAR TCR bank with 2.5 % sys-tem negative sequence voltage, the 3d harmonic current will be equal to 0.22 % of the rated TCR current. 3.3 Harmonic Filter Design Study The SVC harmonic filters are designed to limit the network distortion voltage at the point of common coupling. A system with the most unfavorable SVC compo-nent tolerances was considered when calculating the harmonic distortion. The system frequency deviations and the ambient temperature variations are included in the component tolerances. The total harmonic distortion was calculated for all harmonics, from the 3 td up to the 25 *. Page 15 98.02-25 98-02-25 Rev. 0 Rev. 0 Page 15

The results of the study show that the recommendations presented in IEEE Standard 519-1992 are met at the point of common coupling. The limits on total harmonic distortion are 5.0 % for both voltage and current. The table below lists the results of the 'Harmonic Filter Design Study": RAT Circuit 4160 Volt Bus; Total Harmonic Distortion in Voltage 1.99 % 4160 Volt Bus; Total Harmonic Distortion in Current 1.34 % 6900 Volt Bus; Total Harmonic Distortion in Voltage 1.44 % ERAT Circuit 4160 Volt Bus; Total Harmonic Distortion in Voltage 1.68 % 4160 Volt Bus; Total Harmonic Distortion in Current 4.11 % The values listed in the table above are more conservative (higher) than their. actual values. The calculations of all the generated harmonic voltages and cur-rents were assumed to be at their maximum values. This can never be the case in the actual circuit as each harmonic peaks at a different value of firing angle for the TCR valve. Therefore the peak values will not be added.
- 4. INSULATION COORDINATION The insulation coordination of the SVC equipment is based on ANSI & IEEE stan-dards, experience and theoretical knowledge of voltages that may occur during.
operation and different fault conditions. The SVC and its associated equipment are protected against transient and dynamic overvoltages by means of surge arresters. All surge arresters are based on gapless zinc-oxide ZnO, technology. This type of surge arresters has high-energy absorption capability and excellent protection characteristics.

System Description
Clinton SVC Project Surge arresters are applied line-to-ground on the main SVC bus and across the. TSC thyristor valve. The TCR thyristor valve is protected against overvoltages by means of its break-over diodes (BOD) on each thyristor level, see section 2.5.4
'Thyristor Valves".
The RAT and ERAT transformers are protected by application of surge arresters on both the primary and secondary sides.
- 5. SVC PROTECTION-PHILOSOPHY P56.1 General The protection system provides the following functions:
. protects personnel from electrical accidents
- protects equipment from damage
- isolates faulty equipment if a fault occurs.
Each piece of main circuit equipment is protected by one primary protection and the redundant back-up protections. The main power circuit breakers have redun-dant trip coils; each operated through independent and separate paths from the redundant Lock-Out Relays. Each protective function, primary as well as back-up, triggers the Lock-Out Relays and consequently the two breaker trip coils on each circuit breaker. The existing ERAT, due to its low rating, 15.12 MVA at 65 OC rise, may become overloaded at full capacitive output from the ERAT SVC. The ERAT SVC control and protection system will therefore include an interim overload protection, both in the PHSC system and in the redundant DPU-2000R protections, that matches the thermal overload characteristics of the existing ERAT unit. Upon installation of the new ERAT with LTC, the overload protection will be reset to match the SVC characteristics. 5.2 Primary SVC Protective Functions 5.2.1 Overall Concept The primary protection functions are built-in as part of the PHSC control system, except for the filter bank protection where the SPAJ 160 C protection relays is utilized. These relays are included in the control and protection panel. All protective settings and time delays for the primary SVC protections are defined in the Protection Coordination Report. 5.2.2 TCR and TSC Bank Protection Both the TSC and TCR banks have overcurrent protections implemented in the PHSC control system. Each phase in the TCR and TSC banks is protected with a semi-inverse time characteristic protection, as well as a thermal overload protection, with an alarm and trip stage. Page 17 98-02-25 Rev. 00 Rev. Page 17
A li i ABB Power Systems PiPE
System Description
Clinton SVC Project There is also an instantaneous overcurrent protection for the current in the banks. The activation is within a half cycle. The sum of the current in the delta branch nodes must be zero. If this condition is not met a trip signal will be generated. The sum of the current in the bank must also be zero, otherwise a trip signal is generated. Detection of over-current in either of the TCR and TSC thyristor valves will initiate continuous firing of the thyristors until the main SVC circuit breakers open. There is a current limiter control function for the TCR bank that detects small and slow increases in over-current in the TCR. In such cases the SVC control sys-tem, i.e., PHSC system, will reduce the current back to its nominal value. 5.2.3 TSC Bank Unbalance Protection The capacitor stacks in each TSC phase are arranged in double H configurations. A defective element in a capacitor unit will create an unbalance current that is monitored by the PHSC system. The monitored unbalance current is filtered to represent the fundamental component only. There is a compensation function in the PHSC system for the natural unbalance current in the capacitor stack. The alarm level of the unbalance current is reached by an integrating time function and the trip level is detected with a semi-inverse time characteristic function. 5.2.4 Filter Bank Protection Each of the 5 and 7h/HP harmonic filter branches utilizes the SPAJ 160C type protection relay as primary protection. The current in the filter capacitors contains a considerable part of harmonic fre-quencies, giving distorted voltages across the capacitors. This distortion can im-pose excess voltage stresses on the capacitor units. A three-phase capacitor overvoltage protection is therefore included. This protective function in the SPAJ 160C integrates the capacitor current to form a true replica of the voltage across the capacitor bank. The overvoltage protection has inverse time characteristic to allow for short time overloads. The capacitors units of the capacitor banks are arranged in a Y -Y configuration to enable unbalance detection. Current unbalance protection is provided in the common neutral to detect faults in the capacitor circuits and protect individual capacitor units from overvoltage. This protective function in the SPAJ 160C has two action levels, one alarm level and one trip level. The capacitor banks can be kept in service at the alarm level since it is typically only a small unbalance cur-rent due to one or two blown internal fuses. The capacitor units are made up of a number of internal capacitor elements, typically 30 - 40 capacitor elements for each unit. Each of those elements is protected by its own internal fuse. The 7"h/HP harmonic filter branch has damping resistors in parallel with the filter reactors. The current in these resistors Is monitored by the PHSC system for* thermal overload protection as well as open circuit protection, detected by zero current.

System Description
Clinton SVC Project 5.2.5 Voltage Protection The PHSC system monitors the phase-to-ground and phase-to-phase voltages on the main SVC bus for any abnormal condition, caused by high voltage on the bus or by incorrect operation of the SVC. The protection function is divided in two stages; one slow, but more sensitive, stage and one fast, but less sensitive, stage. 5.2.6 Trip Circuits There are two redundant and independent Lock-Out relays, which are manually reset. They are fed from the independent battery systems, i.e., Lock-Out Relay A is fed from DC supply A and Lock-Out Relay B is fed from DC supply B. All trip actions initiated by protective functions in the PHSC system will activate both Lock-Out relays by separate trip signals. In addition, each Lock-Out relay will activate both trip coil A and B in each of the redundant main circuit breakers. 5.3 Thyristor Protections 5.3.1 Thyristor Valve Overvoltage Protection There is a Break-Over Diode (BOD) built-in into the thyristor electronic unit on each thyristor level in the TCR thyristor valve. This BOD will generate a gate pulse in case excessive voltages are detected across the thyristor. The purpose is to protect the thyristor against overvoltage and failure in cases where the other thyristors in the valve assembly received their gate pulses and are conducting, and the thyristor electronic unit for this particular thyristor did not receive a firing pulse. This is the case, for example, when there is a failure in the fiber optic link. In case of excessive overvoltage on the TCR valve, the BODs may force trigger all thyristors connected in series in one phase. This is possible since the reactor will limit the resulting surge current and simply take over the voltage. The TSC thyristor valve is protected against overvoltage by means of a surge arrester connected across each phase of the thyristor valve. 5.3.2 Thyristor Fault Monitoring A defective thyristor fails as a short circuited unit. This is detected by the thyristor monitoring. The location of the defective thyristor level in the thyristor valve is printed out on the thyristor monitoring printer. The thyristor monitoring system is also capable of detecting faulty emitter diodes and BOD operation, as well as detecting defective thyristor electronic units. The thyristor valves for both the TCR and TSC banks are designed with one redundant level. This means that the SVC system is able to continue operation with one defective thyristor per phase. A trip signal is generated when more than one defective thyristor per phase is detected. Page 19 0 98-02-25 98-02-25 . Rev. Rev. 0 Page 19

Clinton SVC Project 5.3.3 Thyristor Valve Cooling System Protection Every critical parameter in the valve cooling system is continuously monitored by the control and protection system for the thyristor valve cooling system. The criti-cal parameters include flow, temperature, conductivity, and pressure. Any abnormal values above or below the intended setpoint will generate alarm indica-tions followed by trip signal should the condition get worse. The valve cooling control system will provide indications on the cause for the alarm or the trip. The thyristor valve cooling system contains additional and independent trip con-tacts for abnormal low water flow or high temperature as back-up protection should the primary protections in the valve cooling control system fail. These trip contacts send trip signals directly to the Lock-Out relays. The back-up trip con-tact settings are coordinated with the primary protection settings. 5.4 SVC Back-up Protections 5.4.1 Overall Concept The redundant back-up protections are included in the SVC control and protec-tion panel as two (2) identical, but independent, protection relay systems. All protective settings and time delays for the SVC back-up protections are defined in the Protection Coordination Report. 5.4.2 SVC Control System Back-Up Protection There are two (2) independent Distribution Protection Units, DPU 2000R, for SVC control back-up protection. The DPU 2000R protection devices contain numer-ous protection functions. For this application the following protection functions will be enabled:
. Time Overcurrent
- Instantaneous Overcurrent
- Undervoltage
- Overvoltage 5.4.3 Voltage Phase Unbalance Protection Redundant voltage phase unbalance protections are included in the SVC back-up protection scheme to detect and protect against unbalances due to SVC mis-op-eration. The protection is implemented in a type 600 Phase Unbalance Relay and the protection principle is based on measurement of the negative sequence voltage.

Clinton SVC Project 5.4.4 Harmonic Protection The redundant PowerLogic Circuit Monitors are included to monitor the Total Harmonic Distortion (THD) in current and voltage. Any excessive THD will be detected by the circuit monitors and thus generate alarm and trip signals. The PowerLogic Circuit Monitors can monitor harmonic frequencies up to the 313 harmonic. However, it is mainly the typical harmonic frequencies generated due to the SVC TCR operation that are of interest, e.g., 5 , 7 , 11t, and 13"t har-monics.
- 6. DEPENDABILITY AND AVAILABILITY The two Static Var Compensators (SVCs) for the RAT and ERAT systems are being installed to provide steady state, dynamic, and transient voltage support to assure that the auxiliary equipment operate during various system events with a high degree of reliability.
The SVC system is designed and engineered in order to guarantee that the SVC will have correct performance in service, a high reliability, and a normal lifetime. The thyristor valves are standard type assemblies that have built-in redundancy in that at least one thyristor, or thyristor electronic unit, in each leg of the valve assembly can fail without degrading the performance of the overall thyristor valve assembly. Alarms alert the operator to need to correct the problem before failure of additional thyristors or thyristor electronic units. The thyristor valve cooling systems have fully redundant pumps and one redun-dant cooling fan for each system. The main pieces of valve cooling equipment, such as cooling towers, radiators, pressure vessel, cooling pipes, etc., are made of stainless steel for full protection against corrosion. The PHSC control system is used in this application due to its proven track record of high performance and reliability. The PHSC system includes the SVC control system and the majority of the primary protection functions. It contains self-check functions both for the hardware devices as well as the user program sequences for both control and protection functions. In addition, with the built-in diagnostics and self-checks the fault tracing is quick and thorough. Modular design of the electronic system allows the PHSC control system to be returned to service by replacing the circuit board where the fault was identified. The back-up protection is made up of fully redundant, and independent, protection systems for fail-safe performance of the overall SVC system. The redundant back-up protections are fed from independent DC supplies and they activate separate and independent Lock-Out Relays. Further, the two (2) main circuit breakers are fully redundant for increased protection system performance and protection against breaker failure. The main circuit equipment in the Clinton SVC system is selected because of its proven track record and the manufacturers experience with SVC applications. The air core reactors are project specific. However, the basic design is the same as, or similar to, the vast majority of reactors in ABB's SVC installations around the world. Page 21 98-02-25 Rev. 0 Page 21 98-02-25 Rev. 0

Addition-ally, with the internally fused units, the capacitor stacks have built-in redundancy by default. The main circuit breakers are selected to handle a continuous load current of 4,000 Amps while at the same time withstand a fault current in excess of 49 kA with sufficient margin. The 145 kV circuit breaker are standard type dead-tank breakers with built-in bushing type current transformers. The breakers were designed and built based on the SVC breaker specification while maintaining Illi-nois Power Company's breaker requirements for ability to withstand ambient tem-peratures. The auxiliary power supplies for the SVC systems are redundant in most aspects. There are two (2) 480 V, three-phase supplies, for each SVC system. One 480 V supply from the station service system in the main plant and one 480 V supply from a dedicated 4,160 /480 V, 75 kVA, auxiliary power transformer on the SVC main bus. Additionally, there are two (2) 48 V DC sources that are fully independ-ent of each other. Each DC system contains one (1) battery charger, one (1) 48 V battery, and one DC distribution panel. As indicated above, the redundant back-up protections are fed from the separate DC distribution panels for maximum protection performance and system integrity.
