Abstract
In order to locate faults in the double-terminal DC distribution network, the DC circuit breaker and bidirectional thyristor are used to obtain the boundary capacitor voltage recording, and the equivalent time constant is extracted through the capacitor voltage recording of different fault distances. Obtain the relationship curve between different equivalent time constants and fault distance, so as to realize fault location. The simulation results show that the positioning error accuracy is within 1%.
