Today’s LiveWire Spotlight examines FERC Order 847, which announces the Commission’s approval to replace the System Protection Coordination standard (PRC-001-1.1(ii)) with two other standards. PER-006-1 establishes the criteria for Generator Operator training on Composite Protection Systems and Remedial Action Schemes. PRC-027-1 addresses the coordination of BES Protection Systems between interconnected relay owners in the planning time horizon.
PER-006-1, PRC-027-1 and the new definitions of “Protection System Coordination Study”, Operational Planning Analysis” and “Real‐time Assessment” will take effect in the U.S. on 10/1/2020. PRC-001-1.1(ii) will be retired immediately prior to the in-effect date of the new standards.
