1.0 DESCRIPTION

/PURPOSE 1.1 The purpose of this analysis is to perform the following electrical power distribution system studies:

1.1.1 ANSI Format Short-Circuit Study - This analysis will determine asymmetrical and symmetrical short-circuit currents at critical medium voltage busses, based oA ANSI C37.010. VC Summer (VCS) ESF.7.2 kV switchgear/busses and 1DX 7.2 kV switchgear/busý6s will be analyzed to verify that the available fault currents remain within equipment ratings when connected to the proposed new 7.2 kV alternate AC powersource from Parr Hydro.

1.1.2 Medium Voltage Power Cable Ampacity Sizing - This analysis will determine the required sizing of 25 kV rated primary (13.8 kV service) and secondary (7.2 kV service) power cable connecting the new 13.2 kV - 7.2 kV transformer between Parr Hydro and VCS ESF 7.2 kV switchgear/busses. Power cable sizing will determine the calculated derated ampacity for physical installation in rigid conduit, cable tray, underground duct bank and underground direct burial. An alternate analysis will be performed to determine the impact of changing the 25 kV rated secondary power cable to 8 kV along with the possible reduction of cable sizing.

1.1.3 Voltage Regulation - This analysis will verify that the new alternate AC power source to VCS will maintain the required voltage regulation limits on VC Summer (VCS) ESF 7.2 kV switchgear/busses and 1 DX 7.2 kV switchgear/busses. Included in this study will also be the analysis for starting on the largest motors with the new feeder in service. Analysis results will be based on Parr Hydro minimum bus voltage of 13.2 kV and nominal system bus voltage of 13.8 kV.

1.1.4 Transformer Sizing- This analysis will determine'the required sizing of the new alternate AC power source 13.2 kV - 7.2 kV transformer connecting Parr Hydro and VC Summer ESF 7.2 kV switchgear/busses.

1.1.5 Parr Hydro Operating Stability - This analysis will determine the required minimum operating generation at Parr Hydro to support the new alternate AC power source to VCS.

5.5 VCS voltage regulation for ESF 7.2 kV switchgear/busses and 1 DX 7.2 kV switchgear/busses ranges from 93.8% to 102.85% of the rated voltage per calculation DC08360-008 Rev. 4. These values are the design basis for required voltage regulation limits.

5.6 The estimated kVA and kW loads for ESF 7.2 kV switchgear/busses are based on the loading tables detailed in calculation DC08360-006, Rev. 9.

5.7 The new 13.2 - 7.2 kV, 7.5 MVA transformer, XTF-5052, will have a 65°C rise and OA class rating. The design impedance used in calculations is 6.5-percent with an X/R ratio based on ANSI C57 standards, and includes the +1-ANSI design tolerance.

5.8 The new 13.2 - 7.2 kV transformer is designed to either supply the "A" train busses or the "B" train busses, but not both simultaneously.

5.9 Power cable derating calculations for concentric neutral underground distribution cable, rated 750 MCM, 61 strand, 25 kV aluminum, are based on typical positive, -negative, and zero sequence cable impedance values. This cable will be used for both the 13.2 kV and 7.2 kV direct burial installations.

5.10 The distance from the Parr Hydro 13.8 kV tie-in to the VC Summer 7.2 kV switchgear is based on a 3.4 mile circuit length. This circuit length will be confirmed with a surveyed field length value.

5.11 Bus voltage regulation at 'Parr Hydro ranges from a minimum value of 13.2 kV to a nominal value of

- 13.8 kV.

5.12 The maximum available fault current on the 13.8 kV bus at Parr Hydro is 275.15 MVA and is based on the offsite 23 kV - 13.8 kV power source connected and in service. The minimum available fault current is 9.2 MVA based on design-input ECR5055 Rev. 0. The minimumvalue is based -on-the offsite 23 kV-13.8 kV power source disconnected and not in service.

5.13 The cable supplying Charging Pump SI A from the XSW-IDA bus, circuit CSMIA, is a 3/C copper, 8 kV, 410 cable with a circuit length of 273 feet.

5.14 The use of one (1) generator with a 3.1 MVA rating (9.2 MVA short circuit, rating) has insufficient capacity to carry the "A" train loading at VC Summer Nuclear Station calculated at 5.71 MVA. Two (2) operating generators at Parr Hydro have sufficient capacity based on the plant-operating load; however, three (3) generators are required to support the worst-case motor starting analysis. *Based on three (3)

• 3100 kVA generators with assumed sub-transient reactance of 15% operating at Parr Hydro, the calculated available short-circuit MVA is 62 MVAs.' To provide the most flexibility at VC Summer Nuclear Station, all load flow and motor starting analysis will utilize a 62 MVAsC source impedance rating with no contributions from the Diesel Generators.

6.0 RESULTS 6.1 Short-Circuit Analysis:

6.1.1 Two detailed study cases are included for the short-circuit analyses. Both of these studies include the auxiliary power feeds and diesel generators running modeling worst-case conditions. The normal study case is based on the existing plant configuration with transformer XTF31-ES feeding the "B" train loads and transformer XTF4-ES feedings the "A" train loads. The other case study (Case-SC1) is based on the new alternate power source being in service in lieu of transformer XTF4-ES. Transformer XTF31-ES still feeds the "B" train loads and transformer XTF-5052 feeds the "A" train loads. Refer to Attachment #1 for detailed results of these cases. Table 1 represents the momentary ratings for the "Normal" and "SCI" cases while Table 2 provides the interrupting ratings for the same cases.

6.1.2 The short-circuit analysis is performed based on the following study criteria:

> A pre-fault voltage of 1.05 p.u. in accordance with reference 3.1 and ANSI Standard's C37.5 (reference 3.4) and C37.010 (reference 3.3).

> A fixed machine X/R ratio for both motors and generators.

> Medium Voltage circuit breaker interrupting and momentary capability is adjusted based on the nominal 7.2kV and not the equipment ratings of 8.25kV.

> Circuit breaker- calculated short-circuit duties are based on the device maximum through fault current and are adjusted based on C37.010-1979 and Older (Symmetrical Current Rating Basis).

6.1.3 Cable and bus taps are not faulted, since there are no circuit breakers connected directly to these busses for a comparison of equipment ratings with calculated fault duties.

6.1.4 The medium voltage momentary duty or closing and latching duty study calculates the current flowing through the medium voltage system at one-half cycle after the fault occurs in accordance with the ANSI Standard calculation methodology. The calculated asymmetrical rms and asymmetrical peak values are then directly compared with the established medium voltage equipment momentary device capability rating by the ETAP PowerStation software program.

6.1.5 The medium voltage interrupting duty study calculates the current flowing through the medium voltage system for two, three, five and eight cycle breakers in accordance with the ANSI Standard calculation methodology. ANSI C37.010 is used for breakers manufactured and rated under the Symmetrical Current'Rated Standard. The style breaker used at V.C Summer Nuclear Station has an interrupting rating of 33 kA at-a rated voltage of 8.25 kV that is confirmed by manufacturer data sheets. The calculated adjusted interrupting short-circuit currents are directly compared with the established medium voltage equipment interrupting duty device capability rating by the ETAP PowerStation software program.

6.2.1 The cable analysis is based on typical 750 kcmil, single conductor, aluminum, concentric neutral power cable-in accordance SCE&G standards. The required cable ampacity for this application is 314 amps at 13.8 kV service and 601 amps at 7.2 kV service, based on a fully loaded 7.5 MVA transformer. This cable was selected over the 4/0 AWG because of increased cable ampacity. By utilizing the 750 kcmil in lieu of 4/0 AWG, less cables are required for each circuit. The 13.8 kV circuit is I - 750 kcmil cable per phase instead of 2 - 4/0 AWG cables per phase and the 7.2 kV cable is 2 - 750 kcmil cables per phase instead of 3 - 4/0 AWG cables per phase. The following tables are based on NEC requirements and provide ampacity ratings for cables in four (4) different installations for transformer XTF-5052.

6.3.1 The Newton-Raphson method is used to perform the load flow and voltage level analysis. The precision is set to 0.0001 and the maximum number iterations are selected at 99. Busses are flagged if their voltage level is above 102.85-percent or below 93.8-percent of rated nominal voltage.

6.3.2 All case studies are based on having a minimum of three (3) generators running at the Parr Hydro facility with a total generation of 9.3 MVA. A minimum of three (3) generators must be running in order to start the largest motor at VC Summer Nuclear Station.

6.3.3 Eight (8) separate cases are included in the load flow and voltage level -analysis to encompass the different plant configurations and voltage levels. Specific details on each configuration can be detailed on Section 5.

6.3.4 Each load flow and voltage level case study includes five types of reports, i.e., load flow, under-voltage, over-voltage, branch loading and branch losses.

6.3.6 In ETAP PowerStation, Case studies 2 and 4 utilize a LTC transformer to simulate the effects of a voltage regulator. Since the results of case studies 1 and 2 are identical, the transformer never automatically changes tap positions. This also reflects in the identical results from case studies 3 and

4. It is therefore concluded that a voltage regulator is not required because the calculated bus voltages never drop below the minimum design criteria value of 93.8% of nominal voltage. The "A" trains busses and XSWIDX-EX bus maintain a higher voltage when the transformer is placed in the proximity of the VC Summer facility compared to the Parr Hydro facility. Although both locations will achieve the required design criteria, placing the transformer at VC Summer will be more beneficial for voltage regulation on the 7.2 kV busses and more cost effective..

6.3.8 Case studies 6 and 8 utilize a LTC transformer. Since the results of case studies 5 and 6 are identical, the transformer never automatically changes tap positions. However, the results between cases 7 and 8 did change, which simulates the LTC working in case 8. The bus voltages in case 7 are below the required 93.8% of the nominal 7.2 kV. By installing the new XTF-5052 using the design parameters for case 7 and 8, voltage regulators are required on the 7.2 kV system. The results in cases 5 and 6 also have a low percentage of voltage maintained. The voltage on busses XSWIDX-ES, XSWlDA, and XSWlEA are above the required 93.8%, but only by 0.2%. With this marginal result, installation of voltage regulators on the 7.2 kV system is recommended. As stated in Section 6.3.7, these cases are based on the voltage at Parr Hydro dropping to 13.2 kV. If Parr Hydro can guarantee a 13.8 kV nominal voltage, voltage regulators are not be required as determined from Table 5. Excluding the location of the transformer and based on a voltage of 13.2 kV at Parr Hydro, it is concluded that voltage regulators will be required to maintain the 7.2 kV system voltage. Placing the transformer at VC Summer for cases 5 through 8 will be more beneficial for the maintaining system voltage and more cost-effective.

6.3.9 Two (2) motor starting analyses are performed based on a 13.8 kV bus voltage at Parr Hydro (Case 1A and 3A). These cases directly correlate to Case :1 and 3 from Table 5. From the conclusions in Section 6.3.6, only two case studies are required to provide sufficient results for the various scenarios. Table 7 provides the bus voltage in percent for all major busses and SI PUMP A terminal voltage.

6.3.12 When starting the largest motor, the terminal voltage of SI Pump A is above the recommended value of 80% of motor terminal voltage for Cases 5A and 8A, but not Case 7A. Since Case 7 in Table 6 has the lowest bus voltage, the results from the load flow analysis reflect the results for the motor starting analysis. Busses XSWlDX-ES, XSW1DA, and XSW1EA are below the 80% of nominal voltage for Cases 5A and 7A. The'use of a voltage regulator will not correct this problem, because voltage regulators cannot respond fast enough to sudden power surges resulting from motor starting, etc. To prevent the bus voltages from dropping below 80% of rating, a nominal system voltage of 13.8 kV must be sustained at Parr Hydro.

6.4 Transformer Sizing:,

E.4.1 Table 9 provides the MVA loading for the new transformer (XTF-5052) in each of the four study cases.

The transformer will be oversized at 7.5 MVA, in order to account for intermittent power surges that occur during transitional loading between transformers XTF-5 or XTF-4 to XTF-5052. Case studies 1 and 2 have slightly lower MVA ratings than case studies 3 and 4. This is expected because Case's 1 and 2 have the new transformer XTF-5052 located near VC Summer, resulting in lower losses in the 7.2 kV cable compared with Case's 3 and 4.

1) The limiting factor in this study is detailed in Section 6.5.4, Detail #2 (cable in underground duct).

This design parameter rules out the use of a 250 kcmil cable because it does not meet the required calculated ampacity of 301 amps. Per the NEC code, a 350 kcmil cable will be required to carry the necessary ampacity. The calculated cable ampacity of 301 amps per conductor has a lower ampacity rating than an NEC, 3/C - 350 kcmil cable in underground duct (305 amps).

Direct burial cable is not analyzed because it is not a limiting factor as determined in previous studies. From the results in Section 6.2, it is concluded that the temperature of the cable will not affect the overall results, since the calculated cable temperature is 44 0 C compared with a 900 C cable rating. The operating temperature is below the withstand temperature of the cable.

2) The load flow/voltage drop analysis does not significantly change compared with the results detailed in Table 5, Case 1. The short run of 1500 feet will not have a -significant impact between cable sizes 350 kcmil copper and 750 kcmil aluminum. Table 10 provides the results (voltage maintained at the major busses) for the alternate studies.

3) The results from Table 10 are acceptable when the voltage at the Parr Hydro facility is maintained at nominal voltage of 13.8 kV. As the voltage at Parr Hydro decreases, the voltage on the 7.2 kV XSWI DX-ES, XSWI DA, and XSW1 EA busses at VC Summer Nuclear Station will also decrease. When the Parr Hydro system voltage is 13.2 kV, these busses have a marginal percent-maintained voltage. With busses XSW1DX-ES, XSWIDA, and XSWIEA only 0.2%

• above the minimum design parameter of 93.8% of nominal bus rating, it is advantageous to install voltage regulators on the 7.2 kV side of transformer XTF-5052.

4) During motor starting for this same study case, the instantaneous bus voltage in percent of nominal bus voltage is detailed in Table 11. This scenario is similar to Case 1A results (see Table 7).

5) When starting the largest motor, the terminal voltage of SI Pump A is above the recommended minimum value of 80% of motor rated voltage, however'busses XSW1DX-ES, XSWIDA, and XSWIEA are below this value. The use of a voltage regulator alone cannot correct this problem, because the voltage regulator will not react fast enough to be beneficial in compensating for a sudden power surge. To prevent the bus voltages from dropping below 80%, a nominal system voltage of 13.8 kV must be maintained at Parr Hydro, or voltage regulators must be added to the 7.2 kV system and before starting the largest motor, the system voltage must be 100% (7.2 kV).

6.6.1 Analysis of Parr Hydro operating stability is based on loss of the 23 kV - 13.8 kV Off site power source.

In order for Parr Hydro to operate as an alternate AC power source to VC Summer with the 23 kV - 13.8 kV off site power source disconnected, a minimum level of generation capacity is required to support the VC Summer operating load and anticipated worst case motor starting load. As previously stated, the use-of one (1) generator with a 3.1 MVA rating (9.2 MVA short circuit rating) has insufficient capacity to carry the "A" train loading at VC Summer Nuclear Station calculated at 5.71 MVA. Two (2) operating generators at Parr Hydro have sufficient capacity based on the plant-operating load; however, three (3) generators are required to support the worst-case motor starting analysis. Based on three (3) 3100 kVA generators with assumed sub-transient reactance of 15% operating at Parr Hydro, the calculated available short-circuit MVA is 62 MVAsc and the generation MVA is approximately 9 MVA based on an auxiliary plant loading of 300 kVA.

7.0 CONCLUSION

S.

7.1 Short Circuit Analysis:

7.1.1 Both the momentary and interrupting ratings for the "A" train busses and XSWIDX-ES are lower for the "SCI" case versus the "Normal" case. With transformer XTF-5052 feeding the "A"train loads, the short circuit study concludes that the new feeder will not over duty the existing 7.2 kV switchgear and will result in lower fault current levels than the existing plant configuration. Since the "A" train loads are higher than the "B" train loads, there is no benefit to run another scenario with XTF-5052 feeding the "B" train loads.

7.2 Medium Voltage Power Cable Ampacity Sizing" 7.2.1 The worst case analysis for the 13.8 kV cable (using a 25 kV aluminum cable) is in an underground duct bank installation. The NEC allowable ampacity of a 750 kcmil cable in an underground duct bank (one circuit) is 490 amps; whereas, the calculated ampacity is 314 amps. The cable temperature rating is 1050 C and the calculated operating temperature of the cable is 43.570 C. Therefore, 1 - 1/C 750 kcmil, 25 kV aluminum cable per phase achieves the installation criteria for the specified 3.4 mile run.

7.2.2 The worst case analysis for the 7.2 kV cable (using a 25 kV aluminum cable).is also an underground duct bank installation. The NEC allowable ampacity of a 750 kcmil cable in an underground duct bank (three circuit) is 385 amps per. conductor; whereas, the calculated ampacity is 300.5 amps per conductor. The cable temperature rating is 105 0 C and the calculated operating temperature of the cable is 44.05 0 C. Therefore' 2 1/C 750 kcmil, 25 kV aluminum cables per phase achieves the installation criteria for the specified 1500 foot run.

7.3 Voltage Regulation:

7.3.1 The voltage regulation includes two studies that analyze system voltages. The 1 st is the load flow analysis and the 2 nd is the motor starting analysis. The load flow analysis results indicate that it is more beneficial (less line losses) if the transformer is located at VC Summer rather than Parr Hydro. Based on a 13.8 kV system voltage, there is no requirement to have voltage regulators installed on the 7.2 kV system. However, when the 13.8 kV bus voltage drops to 13.2 kV, the 7.2 kV bus voltage results are marginal when compared with the design parameters.

7.3.2 The motor starting analysis has similar results, in that it is more advantageous to locate the transformer near VC Summer.

'most beneficial for the VC Summer system because system stability can be maintained by VC Summer equipment that is not dependant on the Parr Hydro system voltage.

7.4 Transformer Sizing:

7.4.1 A 7.5 MVA transformer has sufficient capacity based on. the existing load of 5.578 MVA that includes line losses and any intermittent surges from transferring from another alternative power source to this power source.

7.5 Alternate 8 kV Copper Cable Scenario:

7.5.1 The Alternate 8 kV Copper Cable Scenario provides similar design results compared with 25 kV aluminum cable. Since the circuit length is only 1500 feet, the voltage drop difference between the two cables types is considered negligible. The load flow analysis results indicate that it is still beneficial to have XTF-5052 located at VC Summer Nuclear Station, and that voltage regulators are beneficial on the 7.2 kV system. The motor starting analysis also has similar results indicating the benefits of voltage regulators. The 350 kcmil copper cable used in this investigation has an underground duct ampacity of 305 amps (three circuit), which is slightly higher than the calculated value of 301 amps, and is therefore suitable for this application. Cable temperature was not determined to be the limiting factor in prior studies detailed in Section 6.2 and therefore does not limit the use of this cable in this application.

Therefore, 2 - 3/C 350 kcmil, 8 kV copper cables (2 conductors per phase) achieves the installation criteria for the specified 1500 foot run.

Document Control Desk Attachment IV LAR 05-3666 RC-06-01 10 Page 1 of 1 UPS APPLICATION PAPER Diesel Start Reliability You can find an excellent and unbiased discussion of diesel generator failure-to-start data in the IEEE Gold Book" Standard 493. on Design of Reliable Industrial and Commercial Power Systems. Appendix L (following) documents a starting reliability of 0.99492 (average) for average diesels. This 99.5% reliability figure may not on the surface appear impressive, but it is. Note that the "99.5" is not an availability value (which may confuse many) and needs to be converted to that. Here's one simplistic way to view it.

Diesels in critical load applications do not need to start every day. How often they are called upon to start depends upon two factors primarily. First is the type & frequency of power anomaly occurrence, and the second is the type of power conditioning device between the utility and the critical load. In the case of Active Power/CAT UPS, there is a minimum of 12 - 13 seconds available in continuous critical load power. This is enough time for diesel start & load acceptance (6 to 7 seconds worst case) with seconds left to "watch" utility before triggering diesel start should the user so elect.

The next step is to determine just how often disturbance events occur (on average) which last beyond the 2 - 3 second "watch" window. An excellent source for this is EPRI. The EPRI DPQ study (following) examines an average database of 24 utilities across the USA (277 monitoring locations). The results clearly document that less than a half dozen of the disturbances measured exceed the window of protection offered by the Active/CAT UPS without reqard to diesel start. From this, you can see that for CAT UPS (Active Power)-protected sites, diesels need to start, on average, just 6 times a year to provide complete protection. At the IEEE 95.5% diesel start reliability, true availability/reliability is tied to the equivalent of 6 x (100% -

99.5% = 0.5%) = 0.03 failure events per year or iust I fail-to-start every 33 yearsl Even this value is higýh conservative since the IEEE gold book figures do not differentiate between high-availability data center back-up gensets and conventional gensets when looking at start failures.

The "99.5%" start reliability would actually approach 99.95% when fuel analysis, redundant starting, and 7x24 test & maintenance procedures are required.

Bear in mind that most critical power sites see 200 hour0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br />s/year or substantially less in standby genset run time, even in CA with it's rolling blackout threat. Therefore major running failures are minimal. Conversely, failure to start data is key, and the CAT/ACTIVE UPS availability failures match or will greatly exceed the 99.999 to 99.9999 availability values of battery-based systems, depending upon redundancy considerations of either system.

Document Control Desk Attachment V LAR 05-3666 RC-06-01 10 Page 1 of 1 LIST OF COMMITMENTS A testing scheme that meets the requirements of NUMARC 87-00, Appendix B, will be developed and implemented prior to declaring the AAC source available for the first time.

Existing structures like the Turbine Building and Parr Hydro will not be modified.

Reverse power sensing relaying will be installed to preclude the possibility of power flowing from the 1 E busses to the AAC (except for short periods during swapping of the AAC source to an EDG).

The AAC source will normally be energized and capable of having its breaker to the 1DX bus closed, but the breaker will remain open.

An Operations procedure will be developed to load the ECCS equipment onto the AAC fed Safeguards bus.

An Operations procedure will be developed to verify the operation of the AAC to supply the 1DA and 1DB busses each refueling outage. The AAC source will normally be energized and monitored at the VCSNS on a continuous basis and will be verified as an appropriate source at least weekly.

The AAC source voltage will be monitored by the plant computer and alarms generated ifthe voltage falls outside specified limits.

VCSNS will supply a work control document to Parr personnel to verify that the diesel is run a minimum of 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> every quarter.

All AAC system components will be in maintenance or monitoring program.

The AAC Source capability testing will be performed in-simulation of a system wide blackout.

When Parr is being depended on as the AAC source due to extended maintenance on one of the EDGs, Parr will be staffed with sufficient personnel to assure power remains available to VCSNS 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> a day, 7 days a week. This requirement will be a central part of the agreement between VCSNS and the management over the Parr Hydro.

The capability of the AAC source will be verified by communicating with personnel at Parr to discuss which units are/will be supplying power as the AAC source.
