The invention relates to a ship direct-current electric propulsion system based on a brushless direct-current motor/generator. In the system, the main generator is a brushless direct current generatoroutputting square wave or rectangular wave alternating current, and the main propulsion motor is a brushless direct current motor driven by the square wave or rectangular wave alternating current. Therefore, the system solves the fluctuation problem of the direct-current power grid on the two sources of the power supply and the load, so that the high-capacity capacitor is removed, the short-circuit fault current is reduced, and the system can realize quick short-circuit fault protection and reliable system complete selective protection.
本发明涉及一种基于无刷直流电机/发电机的船舶直流电力推进系统。系统中,主发电机为输出为方波或矩形波交变电流的无刷直流发电机,主推进电机为方波或矩形波交变电流驱动的无刷直流电机。系统因此而在电源和负载的这两个根源上解决直流电网的波动问题,进而得以去除大容量电容、减小了短路故障电流,使系统可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。
