The invention relates to a power split-type ship direct-current electric propulsion system. Each main generator in the system is provided with a plurality of sets of mutually independent stator winding sets, and each winding set is connected with a rectifier and a fuse to form an independent branch and finally connected to an isolating switch or a circuit breaker on a direct-current bus. A main propulsion motor in the system is provided with a plurality of sets of mutually independent stator winding sets, and each winding set is connected with an inverter and a fuse to form an independent branch and finally connected to an isolating switch or a circuit breaker on a direct-current bus. The main generator and the main propulsion motor are subjected to power shunting through the plurality ofbranches, so that the branch current is reduced, and the system can realize rapid short-circuit fault protection and reliable system complete selective protection.
本发明涉及一种功率分流型船舶直流电力推进系统。该系统中的每台主发电机有相互独立的多套定子绕组集,每个绕组集与整流器、熔断器连接组成一条独立的支路,最后连接到直流母线上的隔离开关或断路器上;该系统中的主推进电机有相互独立的多套定子绕组集,每个绕组集与逆变器、熔断器连接组成一条独立的支路,最后连接到直流母线上的隔离开关或断路器上。主发电机、主推进电机通过以上多个支路的功率分流,支路电流得以减小,可让系统实现快速的短路故障保护以及可靠的系统完全选择性保护。
