Abstract

For high speed DC circuit breaker, this paper proposes two type which is semiconductor type circuit breaker and hybrid type circuit breaker. Semiconductor type circuit breaker consist of two IGBT divers and one Surge Arrester(SA). Hybrid type circuit breaker consistsof one mechanical fast switch and two IGBT drivers and on SA. These three components are composed of parallel circuits.Three prototype(one semiconductor type and two hybrid type) are manufactured and installed at LVDC(+/-750Vdc) demonstration site which is inGochang Power Testing Center of KEPCO Research Institute. Fault tests are performed by AFG(Artificial Fault Generator) and the results, analysis and conclusion are finally presented in this paper.
