This paper has focused on the ±10 kV/1 kA medium voltage DC distribution system simulation and analysis. Firstly, parameters and the topology of the middle-voltage DC system simulation model is proposed. Then, with the application of DC circuit breaker, the interpoles fault transient situations of DC system are analyzed in PSCAD/EMTDC. Finally, the influence of various system parameters is discussed...
One of the constraints to further DC distribution system development is the lack of practical fast DC circuit breaker. In the paper, DC distribution system and breaker protection coordination is discussed. Feasible strategies and methods of protection coordination are proposed. At the same time, based on the actual system with different voltage levels and the circuit breaker prototype test results,...
