  • Calculation of State Grid Relay Protection Settings

    Calculation of State Grid Relay Protection Settings

    Use this Protection Relay Setting Calculator to calculate pickup current, time multiplier settings (TMS), operating time, coordination time interval (CTI), and plug setting multiplier (PSM) using fault current, CT ratio, and IEC 60255 curve parameters. To adapt the grid to the requirements of intelligentization and the dispatching and control cloud technology route, this paper proposes a relay protection setting calculation method for power grid based on distributed parallel computing. First, the cluster architecture of the Spark distributed. Relay coordination is the process of selecting settings that will assure that the relays will operate in a reliable and selective way. T ve.
