The Analysis on Electro-magnetic Transient of SSSC

Abstract

The static synchronous series compensator (SSSC) showed fast speed of adjustment, and good compensation ability. It will be used in electric system more and more in future. In this paper, the second current and recovery voltage, power frequency overvoltage and switching overvoltage of the accessing line with SSSC were simulated and analyzed. And when there was single-phase to ground failure on the line, the impacts on SSSC were also analyzed. In conclusion, the impact of SSSC on the electro-magnetic of the accessing system and protection measures were given.
