In-dock ship generator load test system and method

The invention provides an in-dock ship generator load test system and method, and the system comprises a river water pump set which is used for conveying river water to a heat exchange system in a ship engine room; the heat exchange system is used for regulating and controlling the heat balance state of the generator load test; and the outboard discharging valve is used for discharging the river water subjected to temperature exchange to the seawater side. According to the technical scheme, the displacement of the river water pump is used for replacing the operation condition of the main sea water pump of the engine room, the cooling low-temperature water system is arranged, heat exchange energy transfer is achieved, normal operation of a generator load test is guaranteed, the maximum bottleneck of a dock motor car can be broken through, and the production rhythm and the construction period of ship building are accelerated. 本申请提供了一种坞内船舶发电机负载试验系统及方法，该系统包括：江水泵组，用以将江水输送至船舶机舱内的热量交换系统；热量交换系统，用以调控发电机负载试验的热平衡状态；排舷外阀
