ARTIFICIAL ISLAND STABILITY LIMITATION OPERATING RESTRICTIONS Introduction 01 7-8-04 Sheet 1 of 6

This instruction will serve to provide operating guidance concerning the stable operation of Artificial Island during the extended outage of Keeney-Hope Creek 5015.

  • General Generator Stability Limits Concern for stability is based on the need to operate the system in a manner which will allow generators to remain synchronized with the bulk power system.

Remaining in synchronism is very much dependent on transmission system configuration and generatiion.

The proper control of voltage plays an important role in helping to maintain stability in the system as wel 1.

Rapid changes in the system Csuch as the loss of a major load *c~nter, a large generator, line switching, or a fault occurrence, etc.) have the potential to upset generator s1nchronism.

As a System Operator, the safe and reliable

-operation of the system depends on the ability to recognize that load, excitation levels and var requirements all influence the ability of generating units to remain synchro-nized under adverse conditions.

Increased Mvar output is necessary to maintain stable operation should the next worst contingency happen (such as the loss of the Salem-Deans line, 5021).

Under contingency conditions, the system may not be able to handle full Mw output from the island; therefore, output must be reduced.

The stabi 1 ity guidelines for each machine mu*;t be careful l i fol lowed by both System Operators and Plant Operators.

These are provided at the end of this instruction.

The v o 1 t a g e r e g u 1 a t o r w i 1 1 n o t p r o v i d e m i n i mum c o v e r a g e f o r t h i *;

case.

Due to the extreme importance of maintaining Mw and Mvar 1 imits, one system operator will be assigned solely to monitor and control system voltages.

5021/Salem No. 1 Cross Trip The cross trip scheme has been installed, where the trip of 5021 or the opening of both 5021-500 Kv breakers at.Sal em Jr" Deans causes Salem No. 1 to trip, which eases overall operating restrictions.

The cross trip should be in serv1ce at all fimes except as outlined below.

of the crciss tripping, the remaining units CSalem No. 2 and Hope Creek No. 1) will remain stable on 5023 and 5024.

This will allow all three units to operate.:;.tan* island tiJtal of approximately 3100 g~oss Mw (from Appendix 8).

Cross trip is to be in service 8xcept under the Pollowing conditions:

a.

Island gross tot a 1 is below 2330 Mw due to unit reductions or unit outages with a 1 1

. ' 500 Kv lines in service (refer to Appendi:< 8)

b.

Thunder and 1 ightning

c.

lee/winter storms d

  • Forest fires
f.

Required maintenance work With the return of a unit, enable the cross trip when the island total reaches 2330 Mw C790 Mw on each Sa~em unit and 750 Mw at Hope Creek).

If the cross trip is unavailable when a unit is returning to service, begin reducing the in-service units after the returning unit is synchronized, to maintain an isiand gross Mw output not to exceed 2330 Mw.

Cross Trip Disable To reduce the risk of unnecessary outages on Salem No. 1, adhere to the following guidelines:

Total Island Mw Output Reductions

-Whenever the island gross total is less than 2330 Mw due to a unit outage or reduction, and all 500 Kv lines are available, follow the attached guidelines for the appropriate Mw le~els.

The cross trip shall be disabled at both Salem and Deans when Mw reductions are complete.

S t o r-rr1 S i t u a t i o n s

a.

Thunder and lightning--Whenever storms are within SO miles of Salem. New Freedcim or Deans (as inditated by contracted weather services, Atlantic Electric back-up or OPL storm scope).

The machines will be reduced to the appropriate guidelines for 3-machine/3-line operation with

~G cross trip.

The cross trip scheme shall be disabled upon reaching final Mw values.

  • Ice/Winter storm--Whenever i~ing conditi~ns are predicted by the weather service or confirmed by field reports in either Camden, Trenton, or.

Brunswick Division, the appropriate Mw reductions wi 11 be made for 3-machine/3-1 ine op er at ion and the cross trip disabled.

Similar action should be taken during any winter storm condition if transmission security is in jeopardy.

c.

High winds/Hurricane--Whenever winds are in excess of 50 mph as measured at Camden Switching Station, Deans Switching Station or Artificial Island, the appropriate Mw reductions will be made and the cross tripping scheme will be disabled.

d.

Forest Fires--Whenever forest fires are reported in the area of the Salem/Deans/New Freedom right-of-ways, the appropriate Mw reductions will be made and the cross tripping will be disarmed.

500 Kv line outage lf any one of the three remaining lines comes out of service, reduce all three units to 650 Mw gross and a minimum of 100 Mvars per machine

  • Voltage Regulator Out of Service If a voltage regulator is out of service, reduce 200 Mw on the affected unit until the regulator is returned to service.

Emergency Repairs/Forced outages Emergency repairs may be performed on a p~iority basis without additional action, except those facilities associated with 5021.

5021 -

any work affecting 5021 will require the cross tripping scheme to be disabled and appropriate MW reductions made:*

a.

any relaying on 5021-regular and back-up relays and transfer trips.

To further insure system integrity, T&D has increased the frequency of line patrols.with specific emphasis on the cross over area near New Freedom.

Maintenance Work No routine work on the facil iti~s 1 isted in Appendix A wi 11 be performed, especially where human error ma'{ be a factor.

Specifically this includes:

a.

No line outages

b.

No in-service relay work--the relay technicians are discouraged from working at locations where any mishap may have an impact.

c.

No hot line work

d.

No substation work (i.e. breakers, disconnects) at any 500 Kv station

e.

GETAC work by the laboratory must be carefully evaluated. ~_Request a relay technician to assist in the repair or diagnosis.

Cross Trip Disable/Enable Procedure The two cutoff switches used to disable the cross trip scheme are located one each at Salem and at Deans.

Disable

a.

Whenever it becomes necessary to disable the cross trip scheme, unit output at Salem and Hope Creek must first be reduced to appropriate levels.

b.

Request an operator at Salem and Deans to turn the cutoff switches to the "off" position and apply a r'ed blocking tag for the system operator. C5021/Salern No.
