Abstract

Abstract: The application of DRS digital protection device manufactured by Austria ELIN Corporation as tripping circuit supervisor in Tianhuangping Pumped-Storage Power Station was introduced. Through the comparison with principles of common tripping circuit supervisors, domestic and abroad, take the tripping circuit supervisors of 500KV switch and generator switch as examples, the working principle and defect of the device at different conditions were analyzed in detail. The improvement measures were proposed combining the site requirement, the problems existing in the system were resolved, and a better result was obtained.

Key words: tripping circuit, pumped-storage power station, circuit-break supervision, improvement measure
