IEEE PSRC Update Industry Updates


PES Power System Relaying and Control (PSRC) Committee is responsible for the development of standards, guides and reports covering different aspects of protection and control of electric power systems.

PSRC’s subcommittees have been working diligently.  These subcommittees include:  Advisory, System Protection, Line Protection, Relaying Communications, Relaying Practices, Rotating Machinery Protection, and Substation Protection subcommittees. The Advisory committee continues to strengthen PSRC awareness by preparing technical articles as may be required for the promotion of technical committee working group activities about the art of relaying, and the work of the PSRC. 

Updates on each PSRC technical subcommittee are as follows:

The System Protection (C) Subcommittee reports: C28: C37.242 Guide to the Synchronization, Calibration, Installation and Testing of PMUs for Power System Protection and Control was published

C31: C37.120 Protection System Redundancy for Power System Reliability was approved and awaiting publication. 

Ballots in 2022: C33: C37.233 Guide for Power System Protection Testing;

C39: C37.252 Guide for Testing Automatic Voltage Control Systems in Regional Power Grids;

C38: 2030.12 Protection System Redundancy for Power System Reliability

New Task Force CTF48 to write a summary paper for C37.120 IEEE Guide for Protection System Redundancy for Power System Reliability.

The Line Protection (D) Subcommittee reports:  D39:   Revise C37.104 IEEE Guide for Automatic Reclosing for AC Distribution and Transmission Lines. Ballot Comments have been resolved.

DTF50: Determine if Summary Paper should be created for C37.104

D46: Summary Paper on C37.230 Guide for Protective Relay Applications to Distribution Lines – revising after initial Subcommittee Ballot

The Relaying Communications and Control Subcommittee (H) reports:   IEEE PSRC SC H is responsible for 16 (out of 64) IEEE PSRC Standards, Co-sponsor of 1 standard, and Liasion to new PAR for PNT resiliency standard. It currently has 17 active Working Groups (WGs):  nine are producing or revising IEEE PSRC Standards and eight are generating IEEE PSRC and PES Reports.
