Study on Fault Information Management System for Embedded Relay Protection in Thermoelectric Power Plant

Aiming at problems existing in relay protection equipment of thermoelectric power plant, such as, incomplete information collection quantity and scale, and non unified technical platform of relay protection fault information management, this paper introduced high-reliable embedded substation management hardware platform. Combined with distributed structure of layers in relay protection system of present power plant, this paper built embedded relay protection fault information management system suitable for thermoelectric power plant, with functions including operation monitoring and testing, equipment information management, intellectual diagnosis pre-alarm, data issuing etc. the system has achieved better application effect in project.
