Project 2007-09 Generator Verification
Related Files
 
Status: 
MOD-025-1, MOD-026-1, MOD-027-1, and PRC-019-1 were approved by FERC on March 20, 2014.  In the order approving the standards, FERC directed changes to VSLs for Requirement R6 of MOD-026-1 and Requirement R5 of MOD-027-1.  Those revised VSLs have been posted for NERC Board review, and upon Board action, will be filed.
 
Purpose/Industry Need:
  • To ensure that generators will not trip off-line during specified voltage and frequency excursions or as a result of improper coordination between generator protective relays and generator voltage regulator controls and limit functions (such coordination will include the generating unit’s capabilities).
  • To ensure that generator models accurately reflect the generator’s capabilities and operating characteristics.
New standards to be finalized as part of this project are:
  • PRC-019 — Coordination of Generator Voltage Regulator Controls with Unit Capabilities and Protection
  • PRC-024 — Generator Performance During Frequency and Voltage Excursions
  • MOD-026 — Verification of Models and Data for Generator Excitation System Functions
  • MOD-027 — Verification of Generator Unit Frequency Response
Standards to be revised as part of this project are:
  •  MOD-024 — Verification of Generator Gross and Net Real Power Capability
  •  MOD-025 — Verification of Generator Gross and Net Reactive Power Capability

All six of the standards included in this project address generator verifications needed to support bulk power system reliability. All six of he standards included in this project were originally ”Phase III & IV Planning Measures” that were translated into new or a proposed standards as part of the Version 0 translation effort. Stakeholders have already agreed that there is a reliability-related need for each of these standards as part of the work performed in association with the Phase III & IV Modeling SAR. In addition, each of the standards included in this project has some “fill in the blank” requirements assigned to the Regional Reliability Organization that need to be replaced with more specific “continent-wide” requirements before the standards are approved.
