Abstract:
Primary protection relays and an integrator disclosed for providing primary protection and secondary applications for an electric power delivery system. The primary protection relays obtain signals from, and provide primary protection operations for the power system, and may operate independently from the integrator. An integrator receives signals and status communications from the primary protection relays to perform secondary applications for the electric power delivery system. The secondary applications may include backup protection, system protection, interconnected protection, and automation functions.
