• The IEEE’s patent policy is described in Clause 6 of the IEEE-SA Standards Board Bylaws; • Early identification of patent claims which may be essential for the use of standards under

development is strongly encouraged; • There may be Essential Patent Claims of which the IEEE is not aware. Additionally, neither the

IEEE, the WG, nor the WG chair can ensure the accuracy or completeness of any assurance or whether any such assurance is, in fact, of a Patent Claim that is essential for the use of the standard under development.

• Instruct the WG Secretary to record in the minutes of the relevant WG meeting:

• That the foregoing information was provided and that slides 1 through 4 (and this slide 0, if applicable) were shown;

• That the chair or designee provided an opportunity for participants to identify patent claim(s)/patent application claim(s) and/or the holder of patent claim(s)/patent application claim(s) of which the participant is personally aware and that may be essential for the use of that standard

• Any responses that were given, specifically the patent claim(s)/patent application claim(s) and/or the holder of the patent claim(s)/patent application claim(s) that were identified (if any) and by whom.

• The WG Chair shall ensure that a request is made to any identified holders of potential essential patent claim(s) to complete and submit a Letter of Assurance.

• It is recommended that the WG chair review the guidance in IEEE-SA Standards Board Operations Manual 6.3.5 and in FAQs 14 and 15 on inclusion of potential Essential Patent Claims by incorporation or by reference.

(1) IN2017-06 (1/2) Title : BATTERY AND BATTERY CHARGER SHORT-

CIRCUIT CURRENT CONTRIBUTIONS TO A FAULT ON THE DIRECT CURRENT DISTRIBUTION

IN was Issued on Sep/26/2017 IN indicates one concern:

IEEE std 946-2004 includes non-conservative design recommendation ;

When the battery charger is connected in parallel with the battery, the battery capacitance will prevent the battery charger contribution from rising instantaneously. Therefore, the maximum current that a charger will deliver on short circuit will not typically exceed 150 [percent] of the charger full load ampere rating. Instantaneous battery charger current rise should only become a concern during periods when the battery is disconnected.




(1) IN2017-06 (2/2) IN shows results of several experimental tests by BNL. This technical concern is related to type of Battery Charger. SCR type : Silicon Control Rectifier

Test results showed SCR charger provides 7 -10 times of the rated current during initial 100msec at DC short circuit fault.

This value is beyond 150% which is stated in IEEE.




(2) Japanese NPP’s design status (1/5) (a) Design Standards DC calculations refer SBA* 602.

“Short Circuit Current of Stationary Rechargeable Cells” *SBA : Standard of “Battery Association of Japan” This calculation method is consistent with IEEE std 946.

According to manufacturer remark, fault current’s

contribution from Battery Chargers can be calculated as negligible.




(2) Japanese NPP’s design status (2/5) (b) Japanese Battery Charger’s Supplier A

There are two type of SCR Charger ; - SCR type without Instantaneous Overcurrent protection

(note) In past, there was no available design on instantaneous overcurrent protection.

Fault current will be cut off by Fuse. Because Fuse will be blown-out, the Charger will be

physically isolated. - SCR type without Instantaneous Overcurrent protection

Overcurrent Protection will be activated by “200% of rated current”.

Once the fault point is cleared, the Charger will be started automatically.




(2) Japanese NPP’s design status (3/5) (c) Japanese Battery Charger’s Supplier B

There is only one type of SCR Charger ; - SCR type without Instantaneous Overcurrent protection

Fault current will be cut off by Fuse. Because Fuse will be blown-out, the Charger will be

physically isolated.




(2) Japanese NPP’s design status (4/4) (d) Experimental Data

There was one relevant reference information in past test (1990s). Test Conditions

Charger : around 50A, Battery : 500AH This Charger was SCR type without Instantaneous Overcurrent protection or Fuse, but with MCCB at just outlet of the Charger.

Two cases of test Case 1 : To have a Short Circuit at one DC load during

very Low load condition for the Charger. Case 2 : To have a Short Circuit at one DC load during

Full load condition of the Charger Results of tests

Case 1 : MCCB of Charger was not opened. Case 2 : MCCB of Charger was opened.




(3) Main Discussion in Japan Japanese regulation and Industry discussed how to resolve the issue:

1st Step: Contribution from Charger Magnitude of Contribution from charger and impact on the system should be checked by analysis and/or test. 2nd Step: Short Circuit Protection Evaluation If result of 1st step shows possibility of any impact on protection device by contribution from charger (i.e. unnecessary trip), protection against short circuit current should be evaluated.

DC Load




(4) Conclusion Japanese NPPs refer Japanese standard (i.e. SBA602)

which is equivalent to IEEE std 946. All Japanese NPPs use SCR type Battery Chargers. There are two type of SCR type. Two steps evaluation are considered. 1st step:

Check of Contribution from Charger 2nd step:

Evaluation of Short Circuit Protection if needed Currently discussing how to do step1

Design Change Development

• Enercon prepared two (2) design changes1. Main Generator Upgrade

• Design Summary Report• Instrumentation Interfaces• Siemens Vendor Documentation• Electrical and Mechanical Calculation Revisions

2. SCCW System Upgrade• Design Summary Report• Siemens Vendor Documentation• Piping Support and Stress Analysis• Civil Calculation Revisions• New Instrumentation

9

Design Challenges

• Siemens was responsible for design and implementation of the upgrade, but took exception for all physical electrical modification work.

• Siemens legacy design records did not always match that of the existing plant documentation.

• Siemens sized and routed all piping based on system flow rates, but Enercon was responsible for analyzing for pipe stress.

• Technical specification was prepared by an individual with an electrical background, so level of detail was inconsistent for the other disciplines.

10

Design Challenges (Cont.)

• Design reviews were not very timely, design deliverable dates constantly moved out.

• Project calculation started per the schedule, but receipt of final design inputs resulted in significant delays.

• Siemens drawings are the responsibility of the PG&E to review and approve, normally Enercon can perform the review function, but in this specific contract, the Siemens is our client.

• Siemens was not aware of the details of the Design Change process.

Auto-Transformer Failure (Neal Simmons)

McGuire Nuclear Station November 8, 2017

The auto transformer consists of 3 single phase step-up transformers connected between the Unit 1 230kV yard and the Unit 2 525kV yard, with an installed single phase spare transformer. Prior to the failure, the single phase spare auto transformer was already in use. The Y phase was available as an installed spare. There were no signs of imminent failure from Oil Sampling testing of the auto transformer.

The in-service spare phase (serving as the Y-phase) failed catastrophically. The failure of the in-service spare phase transformer caused extensive collateral damage to the adjacent X-phase transformer. Neither the failed transformer or the damaged transformer could be repaired on site. The 500 kV H1 Bushing faulted internally and failed catastrophically, initiating the event.

Updated voltage schedules were issued Switchyard Voltages went up.

Transmission relocated an auto transformer from another substation to replace the failed transformer. Transmission will be replacing the transformer at the substation. The replacement transformer has been installed and the Autobank has been returned to service. The Generator Voltage Schedule has been revised again for the new transformer.
