NERC Files Petition for Approval of PRC-004-3

On September 15, 2014, in Docket No. ___, NERC filed a petition for FERC’s approval of proposed Reliability Standard PRC-004-3 (Protection System Misoperation Identification and Correction). NERC also requests approval of: (i) a revised definition of “Misoperation” and a new definition of “Composite Protection System” for inclusion in the NERC Glossary of Terms; (ii) the Implementation Plan for the proposed Reliability Standard; (iii) the associated Violation Risk Factors and Violation Severity Levels; and (iv) the retirement of Reliability Standards PRC-004-2.1a (Analysis and Mitigation of Transmission and Generation Protection System Misoperations) and PRC-003-1 (Regional Procedure for Analysis of Misoperations of Transmission and Generation Protection System) as listed in the Implementation Plan.  Proposed PRC-004-3 and the separate Request for Data or Information prepared pursuant to Section 1600 of NERC’s Rules of Procedure, provide the means to accomplish a systematic analysis and correction of the underlying causes of preventable Protection System Misoperations. Proposed Reliability Standard PRC-004-3 replaces Reliability Standards PRC-004-2.1a and PRC-003-1 to create a single Reliability Standard requiring Transmission Owners, Generator Owners, and Distribution Providers to identify and correct causes of Misoperations of certain Protection Systems for Bulk Electric System Elements.
