NPRR081 Automatic Voltage Regulator (AVR) Status
ReasonNERC Reliability Standard VAR-001-1, Requirements R4, R6 and R6.1 require the Transmission Operator to know the status of all transmission Reactive Power resources, including the status of AVRs on generators. In addition, NERC Reliability Standard VAR-002-1, to become effective 8/2/07, requires the Generator Operator to "…operate each generator connected to the interconnected transmission system in the automatic voltage control mode (automatic voltage regulator in service and controlling voltage)…" The requirement does not state that telemetry must be installed in order to be in compliance with this standard. However, installing telemetry which can be archived for historical and auditing purposes, provides a better tracking means than using ERCOT and participant logs. During the PRS discussion of PRR732, Automatic Voltage Regulator (AVR) Status -- Compliance with NERC Reliability Standards PRS agreed that telemetry would facilitate compliance with NERC requirements and will eliminate any question whether ERCOT has captured all data required by NERC. Market Participants and ERCOT agreed that Market Participants should be given sufficient time to install the telemetry technology and such a transition period will extend to the start of the Texas Nodal Market. Therefore, this issue should be addressed in the Nodal Protocols. This NPRR addresses this issue. Facilitates compliance to NERC Reliability Standards
