Relaying Practices Subcommittee (I) reports: I31 is working on IEEE 1613, and I37 on IEEE C37.90. I29 is working on PC37.110 – IEEE Draft Guide for the Application of Current Transformers Used for Protective Relaying Purposes – Revision of C37.110-2007. I32 is working on a Survey of Protective System Test Practices and soliciting PSRC community to identify survey respondents.
- I36 – IEEE PC37.90.2 Standard for Relays, Relay Systems, and Control Devices used for Protection and Control of Electric Power Apparatus – Radiated Electromagnetic Interference Withstand Capability Requirements and Tests – Revision of C37.90.2-2004 – Final draft completed and Subcommittee approved to proceed to Ballot.
- I35 – IEEE PC37.2 Standard Electrical Power System Device Function Numbers, Acronyms, and Contact Designations — Revision of C37.2-2008 – Submitted for Mandatory Editorial Review by IEEE-SA and proceeding to form balloting body.
TF elevated to new WG for existing Guides/Standards:
- I46 – PAR to Revise IEEE C57.13.3-2014 – IEEE Guide for Grounding of Instrument Transformer Secondary Circuits and Cases (expires 2024)
- I47 – PAR to Revise IEEE C37.231-2006(R2012) – IEEE Recommended Practice for Microprocessor Based Protection Equipment Firmware Control (expires 2022)
New TF for existing Guides/Standards expiring soon:
- ITF48 – Review IEEE C37.103-2015 – IEEE Guide for Differential and Polarizing Relay Circuit Testing and determine need for revisions (expires 2025).
Rotating Machinery Protection Subcommittee (J) reports:
- J13 Modeling generator controls (report)
- J14 Power plant protection issues associated with black starting of generators
Both reports essentially complete, incorporating comments from MC officers
Now have four PAR activities:
- J16 Revise C37.101 Generator ground protection: requesting PAR extension (3yr)
- J17 Revise C37.102 AC generator protection: WG ballot initiated, requesting PAR extension (1yr) • J19 Revise C37.106 Abnormal Frequency: WG ballot initiated, sponsor ballot by end of 2021 • J22 Revise C37.96 Motor protection: PAR scope/purpose developed • J21 Motor protection tutorial. New task force JTF23 Investigate the need for a WG to develop a report on synchronous condenser protection
Substation Protection (K) Subcommittee reports:
Published guide! – C37.108-2021, IEEE Guide for Protection of Secondary Network Systems
Established WG’s continuing work: – K10 – SCC21 DER std coordination – K12 – Static Shunt Compensators – K25 – Shunt Capacitors – K26 – Shunt Reactors – K27 – Utility-Consumer Interconnections – K29 – Reducing outage durations
Future Meetings: Sep 20 – 23, 2021 – Virtual • Jan 9 – 12, 2022 –Garden Grove, CA • May 9-12, 2022 – Reno, NV
Working groups, task forces and subcommittees will meet again in September 2021. The PSRC continues to recruit additional participants to offer their expertise and knowledge in the areas of power system relaying.
