Simulation Study on Transient Response of UHVDC Transmission Line Fault

Abstract:

The extraction and analysis of fault information is key to making the transmission line protection configuration scheme. This paper analyzes the mechanism of DC line faults, like lightning, mental and non-mental grounding fault, short to AC line. By referring to actual parameters of Yunnan-Guangdong ±800kV UHVDC transmission system, simulation model is established by PSCAD/EMTDC. According to simulation tests of dc transmission line faults: lightning, grounding fault, high resistance grounding fault and short to DC line, the transient responses of UHVDC line faults are summed up.
