Dynamic Performance Comparison between STATCOM and SVC

Abstract- This paper presents an investigation to the dynamic performance of a PI-type controlled STATCOM for various faulty conditions as well as for different system short circuit ratios, SCR. Furthermore, the performance of the STATCOM is compared with that of conventional static var compensator, SVC. The study is thereby simulated using the PSCAD/EMTDC software. The obtained results reveal superior dynamic performance and fast fault recovery of the STATCOM through different fault conditions as well as with reduced system short circuit ratio, SCR.
