Subject:
" Adequacy of Station Electric Distribution System Voltages" at Hatch Nuclear Plant Units 1 and 2
. Mr. C. H. Griffin:
In compliance with your request of August 24, 1979, and on behalf of the Task Force committee, I am enclosing the study results of the voltage conditions at Plant Hatch Units 1 and 2 station service busses and safety related equipment terminals when fed from the offsite power source.
The study was conducted according to the " guidelines for voltage -
drop calculations" specified in the NRC letter of August 8, 1979. The data for all equipment used in the study is based on manufacturers' test reports, and verified by reading available nameplate data of essential equipment at the plant. The voltage levels and positive sequence impedances for various contingencies at the plant's 230-KV bus, which serves as the offsite power source to the units' auxiliaries, were determined by load flow and short circuit studies respectively.
As requested by the NRC, the analysis of the electric power system at Plant Hatch was performed to determine analytically that the offsite trans-missica system and the onsite distribution system are of " sufficient capacity and capability" to automatically start as well as operate all essential safety loads, within their required voltage ratings, when one unit As under normal shutdown and the second unit is under an accident (such as LOCA) . This event was con-sidered since the simultaneous loss of two units with one under LOCA would make onsite power unavailable (with the exception of the standby diesel generators),
and introduce the highest transient (starting) and steady state (running) loads to the emergency busses, which should be supplied by the offsite power grid.
Briefly, the voltage analysis at the plant consisted of:
A. Determining the worst anticipated transient conditions and consequently calculating the minimum expected voltage levels
- 1) during the transient (motor starting), and 2) after the transient (with total steady state loads).
B. Determining the highest anticipated loads and calculating the maximum expected voltages for these conditions.
C. Verifying by test the accuracy of the analytical method used to calculate the voltage drops.
Voltage profiles for all studied casec are presented in Figures 1 through 16 and accompanied by a discussion of results starting on page 6.
Assumptions, conclusions, recommendations and test verifications appear on pages 2, 4, 5 and 10 respectively.

( The Hatch voltage study reveals that:
. 1. In order for all critical equipment (ca the units' station service) to start and operate safely, when fed from the 230-KV tus (offsite power source), the voltage level on the bus should fall within the range of 98% to 104% of 230-KV. Although the 230-KV bus interconnects four lines and one 230/500-KV auto-transformer (see attached single line diagrams), which more than
. satisfy the NRC requirement of two lines, load flow studies have shown that under certain contingencies and maximum load condi-
~
tions on tha transmission system, the voltage would collapse to a level lower than the acceptable 98%. The simplest and most convenient way to remedy the situation is to operate the Plant McManus (closest plant to Hatch) gas turbine units at full capacity and 104% voltage regulation, if the following conditions exist: 1) Hatch Unit 1 or Unit 2 or the 230/500-KV autobank is .
out of service (normal shutdown or maintenance),2) the system is experiencing peak demand, and 3) GPC is selling about 400 MW to Florida. If this recommendation is not implemented due to the high cost of operating the gas turbines, alternate solutions are suggested by the planning department in Mr. Bill May's attached letter of November 5.
It should be noted that historically the simultaneous loss of Hatch Units 1 and 2 has never resulted in a voltage lower than 99%
on the 230-KV bus. However, this case was never experienced under
( marimum load conditions.
- 2. Although the present CV-7 relays' voltage-time settings on all emergency busses have so far proven to be adequate, the study indicates that new tap settings of 93V. (80% of nominal) and time dial 2 would override the transient undervoltage condition, which could be caused by the simultaneous startup of several essential motors during a LOCA.
- 3. All starting station service (SSS) transformers for Units 1 and 2 are of sutficient capacity to carry all present loads. However, any future load expansion would require the re-evaluation of the SSS transformers' safety margins, and might warrant their replace-ment with banks of higher capacities, or the addition of new banks.
This study was the combined effort of several GPC and SCSI engineers whose contributions were very essential in attaining precise information and results.

Subject:
Hatch Units Study Offsite Voltage Source Contingency Analysis The analysis of offsite voltage sources was based on the system for 1980 at. a projected system peak of 10,838 MR. For most cases the generator voltage schedule was taken to be 103% at 500 KV and 102% at 230 KV generator busses. - Should a higher or lower voltage schedule be used, then the voltages at the Hatch 230-KV bus would be changed by a comparable amount. Other assumptions taken as part of the base system conditions were an interchange level of 400 MR to Florida and no generation at Plant McManus. Recognition of problem contingencies was based on the results of the study of voltage requirements at the station auxiliary system emergency busses. For present auxiliary transformer tap settings the 230-KV bus voltage limits are 98% to 104%. Contingencies for which problems arose with the above system conditions and constraints were: l. (1) the simultaneous loss of Units 1 & 2, and (2) the loss of the 500/230-KV autobank while Unit 1 is down for maint-enance, or vice versa. For the simultaneous outage of Units 1 & 2, the 230-KV bus voltage dropped to 92%. The minimum voltage of 98% can be attained in the following ways: (1) by installing approximately 350 MVARS of capacitors in the area, or (2) by reducing to zero interchange with Florida and installing approx-imately 75 MVARS of capacitors in the area, or (3) by operating McManus steam units at full capacity and installing 201 MVARS of capacitors in the area. For the second set of contingencies with the 500/230-KV autobank out and Unit 1 off, the 230-KV bus voltage dropped to 79%. The 98% minimum can be achieved by: (1) installing approximately 300 MVARS of capacitors in the area, or by (2) reducing to zero interchange with Florida and installing approximately 150 MVARS of capacitors in the area, or by (3) operating McManus steam units at full capacity and installing 160 MVARS of capacitors in the area. 1581 132
. Page Two The above results are summarized in the table below.

Dear Tony:
Enclosed is the final report regarding voltage regulation of the Hatch Units 1 and 2 auxiliary systems in response to the Nuclear Regulatory Commission's letter of August 8,1979. Also enclosed for all committee members is an approval form. Please complete this form and return by November 26, 1979. We found a discrepancy in the transfomer data we received from Mr. M. D. Faulkenberry for station service transfomer 1CD, GE serial number G-853166, 4160-600 V,1400 kVA. Mr. Larry Brinson indicated from the field this transfomer is identical to other 4160-600v~ olt transfomers except the available tap settings are 4360 V, 4260 V, 4160 V, 4055 V and 3950 V. Other transformers (lA, 1B, 1C, and 10) have taps of 4260 V, 4160 V, 4055 V, 3950 V and 3850 V. Mr. Brinson indicated that all these transformers were set on tap position number 2 which corresponds to 4260 V for 1CD and 4160 V for lA, 1B,1C and 10. Since transfomer 1CD is a standby for 1C and 10, it is recommended that it be placed on tap position number 3 or 4160 V. Sincerely,

Introduction i Objective: This study was conducted to determine the voltage limit require-ments of the 230 kV system at Plant Hatch. These voltage limits are required to provide adequate voltage regulation and motor starting capability in the operation of the station auxiliary system emergency busses for Hatch Units 1
. and 2 from the offsite power source (230 kV system) under expected system conditjons. This study did not consider the onsite power source (diesel generators).
Scoce: To determine the minimum and maximum voltage limits for the offsite power source to enable adequate operation of Hatch Units 1 and 2 emergency - busses under expected system conditions. Also to verify the analytical study by comparison with field readings. 1581 140 e
Assumptions f a The following assumptions are made for voltage study calculations.
- 1. The maximum station auxiliary bus voltage occurs when the offsite power source voltage is at its maximum ~ expected level and the auxiliary bus loads are at their minimum expected level.
- 2. The minimum station auxiliary bus voltage occurs when the offsite power source voltage is at its minimum expected level and the auxiliary bus loads are at their maximum expe:ted level.
- 3. The worst motor starting condition occurs under LOCA (loss of coolant accident) during automatic and simultaneous starting of the emergency Rev. I loads. Motor starting is studied for the minimum system voltage and LOCA condition with the remaining unit being under normal shutdown condition.
- 4. The maximum expected normal running load is the same as that recorded on 9-14-79 (Appendix A) when both units were under normal operation.
( 5. All 600 V bus loads remain the same under all study cases except under the motor starting condition. ,
- 6. A power factor of 85% for the running load when power factor data is not available.
- 7. The expected mininum and maximum system equivalent positive sequence impedances are 0.042 + j0.937 and 0.12 + jl.49, respectively. These impedances are in percent on a 100 MVA, 230 kV base. The minimum impedance represents normal system with all units and lines in service.
The maximum impedance represents Hatch Units 1 and 2 off-line system , condition.
- 8. The minimum system impedance is used with the maximum system voltage condition and the maximum. system impedance is used with the minimum system voltage condition.
- 9. The test report impedances are used for all auxiliary transformers.
- 10. All auxiliary transformers have tap settings :f 1.0 p.u. in service.
2 1581 141
- 11. All safety related 600 V motors have nameplate ratings of 550 V.
- 12. All safety related motors have 757, motor voltage starting capability.
- 13. During normal operation, permissible voltage variation for a motor is
+10", of its nameplate voltage rating.
14 X to R ratios used for the 4160-600 V transformers are 8 for 1400 kVA and 3 for 225 kVA and smaller. . l 1561142 0 6 3
Conclusions
- 1. Since present-day field readings are used to estimate the bus loads for the study cases without any supportive past field readings, a 5% load margin should be assumed to account for load fluctuations in the field readings.
Case 2A, Figures 10-13, show the voltage and load levels with this 5% margin.
- 2. For present tap setting of 1.0 pu in all auxiliary transformers and minimum and maximum study loads with 5% load margin, the auxiliary system can sustain a maximum 230 kV bus voltage of 239.2.kV (104%) and a minimum 230 kV bus voltage of 225.40 kV (98%).
- 3. For a tap setting change from 1.0 pu to 0.975 pu in the RAT's, the .
auxiliary system can sustain a maximum of 233.2 kV (101.45)to a minimum of 219.4 kV (95.4%) range for the 230 kV bus voltage for the bus loads as mentioner in conclusion 1 above.
- 4. No new loads which would affect the study cases can be added to the existing busses.
- 5. The bus loads under maximum auxiliary load condition are within transformer's rated kVA capabilities.
- 6. Under the maximum and minimum system voltage conditions, the motor terminal voltages are acceptable for the respective minimuni and maximum bus load conditions.
- 7. For the worst case motor starting, motor terminal voltages of the starting motors are within their capabilities.
- 8. Should the expected 230 kV bus voltages be other than detennined in this report (i.e.104% - 98% of 230 kV), the allowable 230 kV bus voltage band for auxiliary system regulation may be less than 6%. . Determination of the optimum tap settings can only be made once the expected 230 kV bus voltages are provided.
1581 143 4
( Reconmendations
- 1. The voltage levels for the 230 kV bus should be maintained within a 5%
band. An example of this is 105 to 100% of 230 kV.
~
- 2. Tap settings in all auxiliary transformers should be 1.0 pu (the existing tap setting in the field).
- 3. Future load additions should be reviewed carefully to determine if they affect the study results.
- 4. The auxiliary bus load should be recorded on a routine basis per the procedure outlined in Appendix A. -
- 5. An attempt should be maae to balance the loads on the X and Y windings of the three winding transformers. These transformers are: UAT's (Unit Auxiliary Transformers) 1A and 2A and RAT's ID and 2D.

Discussion of Results Seven cases have been investigated to determine the steady-state voltage regulation, motor starting arid verification of calculated results versus field readings. Cases 1, 2, and 3 investigate the minimum and maximum auxiliary system voltages for transient and steady-state conditions using load data given in Appendices A, B, C and D. Portions of this load data is obtained from field readings and no margin has been added to it. For these three cases the minimum allowable system voltage is 97% of 230 kV. Case 1A restudies the voltage regulation of Case 1 with the system voltage of 105% of 230 kV. Case 2A restudies the voltage regulation of Case 2 with loads 5% larger than that based on field 2 readings. The minimum acceptable system voltage for Case 2A is 98% of 230 kV. The maximum acceptable 2.30 kV bus voltage for Cases 1 and 1A is 104% of 230 kV. Case 3A is the motor starting case for the system voltage of 98% of 230 kV and loads 5% larger than that based on field readings shown in Case 3.
'These cases are run using the existing tap settings in all auxiliary transformers of 1.0 p.u. A tap setting change to 0.975 p.u. in the RAT's
( would yield an allowable 230 kV bus voltage operating range of 101.4% to 95.4% for cases similar to Case 2A. These cases have the 5% increase in loads . for margin. For other tap settines the allowable 230 kV bus voltage range would be different but still within a fd band. It is important to note that Case 1 A, Figure 9 gives the maximum 600 V bus voltage of 111.13% on 550 V motor base. This voltage although outside the t10% of the 550 V motor continuous rating is considered acceptable for
- a short duration for the following reasons. !
(a) The overvoltage exceeds the rated continuous voltage by only 1.13% at the 600 V bus. (b) The motor terminal voltage will be lower due to cable drop from the 600 volt bus to the motor terminal. (c) These voltages of 111.13% are expected to occur only on rare occasions and for only short durations when the 230 kV system voltage reaches a maximum of 241.5 kV. t (d) The consequences of high motor voltage is loss of motor insula-tion life. The short duration expected is not expected to yield 1581 145 6
. any measurable loss of life in the motor.
(e) It is likely that the 230 kV bus voltage will be regulated below 241.5 kV in which case the 600 V bus voltages would g never exceed 110% of the.550 volt motor voltage. Case 4 verifies the calculating techniques as documented below. Voltace Study Cases: The following are considered for bus voltage regulation and motor starting under worst case conditions. Case 1 - Maximum system voltage and minimum load condition This condition occurs when one unit at the plant is under normal - operation and the other unit at the plant is under re-fueling operation. See Figures 1-2 for the detail voltage and load levels. The resultant voltages are within acceptable levels. The loads are considered as follows. 1* . Unit under normal operation: 4 kV and 550 V loads: Load for emergency busses from Appendix B g with assumed power factor of 0.85.
- 2. Unit under re-fueling: -

.888 pf .
550 V Loads: Load for emergency busses from Appendix B t Case 2 - Minimum system voltage and maximum load condition. This is the condition of simultaneous shutdown when one unit at the plant is under LOCA and the other unit at the plant is under normal shutdown. See 1581 146
Figures 3-6 for the detail voltage and load levels. The resultant voltages are within acceptable levels. The following bus loads are considered:
- 1. Unit Under LOCA:
4 kV loads: Loads per Appendix A with.a deduction for the two reactor recirc water pumps on Busses A and B at their 80% full load kVA and .85 pf Rev. 1 and the addition of two core spray pumps and four RHR pumps. Two reactor recirc water oumps drop out automatically durino LOCA condition. 550 V loads: Loads per Appendix A ,
- 2. Unit Under Normal Shutdown:
4 kV loads: Loads per Appendix A plus two core spray pumps and four RHR pumps. Rev. 1 550 V loads: Loads per Appendix A
- 3. Loads on each reserve auxiliary transformer (RAT) for this case are as r
follows: LOAD ( MVA. of ) RAT - 1D or 2D Unit & Condition RAT-1C or 2C X - Winding Y - Winding Unit 1
- a. LOCA 9.46, 0.850 9.39 0.865 14.78 0.868
- b. Normal Shutdown 19.33, 0.850 9.39 0.865 14.78 0.868 Unit 2
- a. LOCA 8.86, 0.850 12.94 0.868 10.76 0.862
- b. Normal Shutdown 18.74, 0.850 12.94 0.868 10.76 0.862 NOTE: RAT's ratings are as follows:
1C or 2C: 230-4.16 kV,15/20/25/28 MVA, 0A/FA/F0A/650C 1D or 20: 230-4.16-4.16 kV,18/24/30/33.6 MVA, 0A/FA/F0A/65 C Rey, 1 X-Winding - 9/12/15/16.811VA, 0A/FA/F0A/65 0C Y-Winding - 9/12/15/16.8 MVA, 0A/FA/F0A/65 0C 1581 147 8
Case 3 - flotor starting under minimum system voltage and maximum auxiliary bus loads. Simultaneous starting of two core spray pumps and four RHR pumps because of the automatic action due to LOCA condition and a condensate pump because of the dropout of one of the running condensate pumps is considered the worst Rev. 1 motor starting condition when Unit 1 is under LOCA and Unit 2 is under normal shutdown condition. See Figure 7 for the detail voltage and load levels. The starting motors terminal voltages are within acceptable levels. The following loads are considered:
- 1. Unit 1 Under LOCA -
4 kV loads: Same as Item 1 under Case 2 above minus the full load kVA nf Rev. I two core spray pumps and four RHR pumps that are assumed to be started. 550 V loads: Same as Item 1 under Case 2 above and the addition of 150 kVA M0V's load (intermitten load) to the 4.16 kV Busses lE, 2E,1G, and 2G. This intermittent load is adopted from the FSAR's for Units 1 and 2. (
- 2. Unit 2 Under Normal Shutdown Condition 4 kV and 550 V loads: Same as Item 2 under Case 2.
Case 1 A - Maximum voltage and minimum load condition. This case is same as Case 1 except that the 230 kV bus voltage is raised to 105%. This case is stud.ied to determine the auxiliary system voltag6s.for the 230 kV system equipments maximum voltage rating. See Figures 8 and 9 for the detail voltage and load level. The 4 kV and 550 V loads considered are the same as those for Case 1. Case 2A - Minimum system voltage and maximum load condition. This case is same as Case 2 except that the load based on the field readings on each bus is raised.by 5% to determine the minimum acceptable system voltage. Figures 10-13 show the voltage and load levels. The required system voltage is 987 of 230 kV at the 230 kV bus. g 1581 148
Case 3A - Motor starting under minimum system voltage and maximum auxiliary bus loads. This case is same as Case 3 except the system voltage is 98%, the minimum required for the maximum load condition of Case 2A, and the 5% higher loads based on the field readings. See Figure 14 for the detail voltage and load levels. The starting motors terminal voltages are within acceptable levels. - Test and Analysis Verification: To verify the adequacy of the analytical results for the afore- . mentioned voltage studies, a test was performed at the plant. This test was performed on October 10, 1979 with the existing system and unit con-ditions at the plant. This test was intended to demonstrate our ability to calculate the voltage at various busses accurately and not to duplicate the analytical cases studied. Field testing which duplicates these specific analytical cases is impractical. The test procedure and test readings are documented in Appendix C. The bus loads and source voltages (230 kV bus ( and Generator bus) are used to run the same load flow program as that used for the analytical studies to determine the voltage at various 4.16 kV busses. A tabulation on page C-15 of Appendix C shows the bus loads used for Case 4 which presents the verification of analytical study. Figures 15 and 16 show the results for this case. The calculated bus voltages are very close to the field readings. The maximum variation was found on the combined busses 1A and 1B which was 0.58%. The field readings cannot be duplicated exactly because of
- 1. Metering accuracy
- 2. Readings cannot be taken at the same instant at all busses
- 3. Unbalance in the voltage and ampere readings.
The variations found in the calculated values when compared to the field readings are well within an acceptable range for reasons mentioned above and therefore the calculating technique used in the analytical studies is considered acceptable. 1 1581 149 10

Hatch Station Auxiliary Test Procedures Purcose: The purpose of this test is to verify analytical studies of the Hatch 1 and 2 station auxiliary voltage profile as required by the NRC's latest request. Secoe: This test is developed to determine the volt:.ge profile of the
~
auxiliary system busses when they are being supplied from the starting system.when the system is operating in the steady-state. The following test procedures have been developed using existing plant metering equip-ment. Additional tests may be required in the future to verify motor starting analytical studies but is not addressed in this test procedure. Drocedures: li Determine the service condition of the 230kV and 500kV lines at Hatch and record this information on Form 1.
