The embodiment of the invention discloses a ship hybrid power system based on a multi-source flexible direct-current looped network and a control method of the ship hybrid power system, and can be applied to the technical field of ship control. According to the system, after the natural gas power module, the hydrogen fuel cell power module and the lithium iron phosphate battery power module are arranged, the natural gas power module is connected with the ship gearbox through the first clutch, so that the state that the natural gas power module outputs power to the ship is controlled through the on-off state of the first clutch; meanwhile, the hydrogen fuel cell power module and the lithium iron phosphate battery power module are connected with the multi-source flexible direct-current looped network, so that the states of outputting power to the ship gearbox by the hydrogen fuel cell power module and the lithium iron phosphate battery power module can be controlled through the on-off states of a second clutch and a third clutch; therefore, various multi-source hybrid power modes can be provided for the ship, and the problems that a pure natural gas engine is insufficient in power and a pure electric ship is short in endurance mileage are effectively solved.
本申请实施例公开了一种基于多源柔性直流环网的船舶混合动力系统及其控制方法,可应用于船舶控制技术领域。本申请系统通过分别设置天然气动力模块、氢燃料电池动力模块和磷酸铁锂电池动力模块后,并设置天然气动力模块通过第一离合器与船舶齿轮箱连接,以通过第一离合器的开关状态控制天然气动力模块向船舶输出动力的状态,同时设置氢燃料电池动力模块和磷酸铁锂电池动力模块均与多源柔性直流环网连接,从而可以通过第二离合器和第三离合器的开关状态控制氢燃料电池动力模块和磷酸铁锂电池动力模块向船舶齿轮箱输出动力的状态,进而可以为船舶提供多种多源混合动力模式,有效解决纯天然气发动机功率不足、纯电力船舶续航里程较短的问题。
