摘　　要：针对低速机带定距桨并配置抱轴式励磁轴带发电机和小容量储能电池的混合动力系统,以某汽车运输船为例,分析轴带发电机的运行条件和工况、励磁电流的控制和调节、轴带发电机和主发电机并车时储能电池系统运行和不运行时的控制逻辑;利用储能电池的充放电特性降低电网负荷的波动,实现对电网削峰填谷的功能,降低了主发电机油耗和二氧化碳排放;在主机转速变化导致轴带发电机不能正常运行的情况下,通过储能电池和电站管理的逻辑控制,让备用发电机能够及时并网和轴带发电机平稳退网,防止全船失电现象的发生,确保船舶能够安全航行。经实船试验验证,提出的混合动力系统控制逻辑设计安全可靠。Aiming at the hybrid power system of low speed machine with fixed pitch propeller and equipped with holding shaft exciting shaft generator and small capacity energy storage battery,taking an automobile carrier as an example,the operating conditions and working conditions of shaft generator,the control and regulation of excitation current,and the control logic of energy storage battery system running and not running when shaft generator and main generator are combined were analyzed.The charge and discharge characteristics of the energy storage battery were used to reduce the load fluctuation of the power grid,achieve the function of peaking and valley filling,and reduce the fuel consumption and carbon dioxide emission of the main generator.In the case that the shaft generator cannot operate normally due to the change of the main engine speed,the storage battery and the logic control of the power station management could make the standby generator be connected to the grid in time and the shaft generator be smoothly withdrawn from the grid,so as to prevent the power loss of the whole ship and ensure the safe navigation of the ship.The control logic design of the hybrid power system has been proved to be safe and reliable by ship test.
