Technical Operations Subcommittee Report: Progress on TOS Goals (June 10-11, 2004)

This report details the progress of the Technical Operations Subcommittee (TOS) as of June 10-11, 2004, chaired by Gary S. Tarplee. Key achievements include the completion of the "Automatic Voltage Regulator (AVR) Policy" and the design and performance criteria for power system stabilizers. A review of the 2002-2003 disturbance reports is 60% complete, with updates on synchronization and underfrequency load shedding guidelines due for approval in October. The report emphasizes the requirement of AVRs on synchronous generators and outlines performance standards as mandated by NERC/WECC.

  1. TECHNICAL OPERATION SUBCOMMITTEE Report to Operating Committee June 10 – June 11 2004 Gary S. Tarplee - Chair

  2. Progress on 2004 TOS Goals • Complete generator “Automatic Voltage Regulator (AVR) Policy”. • Completed • Complete Power System Stabilizer Design and Performance Criteria”. • Completed • Complete review of 2002-2003 Disturbance Reports. • 60% complete • Update the following guidelines: • “Guidelines for Time Synchronization of Protection, Control and Monitoring”. • “Underfrequency Load Shedding Relay Application Guide”. • Both have completed due process. • Both will seek approval at October’s OC meeting.

  3. OC Approval Items • “Automatic Voltage Regulator Policy Statement”. • Requires AVRs on all synchronous generators. • 30 MVA and above new or existing units that are replacing their exciter shall be required to have high initial response excitation systems. • AVR equipment shall be tested and calibrated in conjunction with the balance of the excitation system as often as necessary, but no less frequently than required by NERC/WECC Standards. • Outlines minimum performance requirements. • Completed due process and approved by TOS.
