An auto-reclosing scheme for DC circuit breaker in VSC-HVDC transmission system

An auto-reclosing scheme for DC circuit breaker in VSC-HVDC transmission system

When a DC line fault happens, the converter will be blocked instantly. This leads to an interruption of power transmission and influences the stability of DC and AC systems. To avoid the blocking of converters, this paper presents a novel protection scheme for VSC-HVDC system, which consists fault i...
