Improved service reliability for rural electric customers - innovative auto-restoration following loss of primary source interconnection

摘要

Plumas-Sierra Rural Electric Cooperative (PSREC) has two interconnections with large investor-owned electric utilities. Presently, PSREC normally operates solely connected to the Pacific Gas and Electric (PGon6;E) system via a radially fed line. This connection to PGon6;E is subject to service interruption for events on the PGon6;E line or connecting facility. Loss of this PGon6;E interconnection drops the entire PSREC customer load. An alternative service interconnection is available with Sierra Pacific Power Company (SPPCo) on another part of the system. However, this alternative source does not have the capacity to carry the entire PSREC customer load.
