How we helped
SynchroGrid performed engineering calculations to verify that relay settings complied with PRC-025-2 for four Cottonwood generation units. The purpose of this standard is to prevent unnecessary tripping of generators and equipment damage by correctly setting load-responsive relays.
SynchroGrid’s responsibilities included reviewing relay one-line/three-line diagrams and applicable relay settings, performing calculations to verify relay settings complied with PRC-025, suggesting settings changes for non-compliant relays, and producing compliance reports.
