The invention provides a direct-current networking electric propulsion system of a hybrid power ship based on permanent magnet synchronous generation. The output of an engine is connected with the input of a permanent magnet synchronous generator; the output of the permanent magnet synchronous generator is connected with one input of a rectification module; the output of a multipower module is correspondingly connected with the input of the rectification module; the output of the rectification module is connected with a direct-current bus; inputs of a power utilization modules are connected with the direct-current bus; one end of a first power switch is connected with one terminal of a direct-current bus of one electric propulsion subsystem, and the other end of the first power switch is connected with the other terminal of a direct-current bus of the other electric propulsion subsystem; and all of the direct-current buses are connected through the first power switch so as to form a closed loop. The direct-current networking electric propulsion system has the advantages of multipower compatibility, no limitation to the speed fluctuation rate, short response time and wide adjustmentrange.

    本发明提供一种基于永磁同步发电的混合动力船舶直流组网电力推进系统,发动机的输出与永磁同步发电机的输入连接;永磁同步发电机的输出与整流模块的一个输入连接;多电源模块的输出与整流模块的输入对应连接;整流模块的输出与直流母线连接;用电模块的输入都与直流母线连接;第一电力开关的一端与该电力推进子系统的直流母线的一个终端相连,另一端与另一个电力推进子系统的直流母线的另一个终端连接;所有直流母线通过第一电力开关连接后,形成封闭的环形。其优点在于具有多电源兼容性,不受转速波动率限制,响应时间快,调节范围广。
