Topology of Generator Outlet Circuit Breaker and Short Circuit Fault Breaking Characteristics

The generator circuit breaker is of great significance to improve the reliability of the operation of the generator and transformer and ensure the stability of electricity consumption in the event of failure, and with the increase of the capacity of the power system, the design and development of the generator outlet circuit breaker has brought greater problems. In this paper, a topology of a large-capacity generator circuit breaker is designed and analyzed, and the action sequence of each module under the maximum asymmetry extreme fault current is simulated by PSCAD simulation, which provides some guidance for the development of large-capacity generator circuit breaker.
