Research on Relaying Secondary Device Evaluation System of Intelligent Substation Based on Platen Status Monitoring

Relaying secondary device as the first line of defense for power grid stability, is the guardian of power grid safety. To improve the automation level of evaluation for secondary maintenance worker of relaying, a relaying secondary device evaluation system of intelligent substation based on platen condition monitoring is proposed. The system has implemented communication function of the device such as the hard platen of relaying device, telemetry, remote signaling, remote control, setting and so on, comprehensively collect the on/off status of hard platen for each device, analyze the operation processing of examinee, create the achievement and analysis. Increasing the professional quality and ability level of secondary maintenance worker of relaying over all , reduce the probability of operation errors, ensure the safety of grid.
