The invention discloses a control method of a hybrid power locomotive and a related assembly, and relates to the field of locomotive power supply. A second voltage output by a controllable rectification module is adjusted through a rectification module, namely, the voltage input to an intermediate direct current circuit by a diesel engine power supply module is adjusted; in other words, the voltage difference between the voltages generated by the contact net and the diesel engine is eliminated, so that the two power sources can supply power to the hybrid power locomotive at the same time; meanwhile, through connection and disconnection between the input end of the controllable switch module and the first output end and between the input end of the controllable switch module and the second output end, control over the connection mode of the diesel engine power supply module and the middle direct-current circuit is achieved, namely control over the connection relation between the diesel engine power supply module and an auxiliary load and a traction system of the hybrid power locomotive is achieved; in other words, control over power source switching is achieved through control over the controllable switch module, power supply cannot be lost in the power source switching process, and seamless switching can be achieved.

    本发明公开了一种混合动力机车的控制方法及相关组件,涉及机车供电领域,通过整流模块调节可控整流模块输出的第二电压,即调节柴油机供电模块输入到中间直流电路上的电压,也即消除了接触网和柴油机两种动力源产生的电压之间的压差,使得两种动力源可以同时为混合动力机车供电;同时,通过可控开关模块的输入端与第一输出端及第二输出端之间的导通与断开,实现了对柴油机供电模块与中间直流电路的连接方式的控制,即实现了对柴油机供电模块与混合动力机车的辅助负载和牵引系统的连接关系的控制,也即通过对可控开关模块的控制实现了对动力源切换的控制,在进行动力源切换的过程中,不会失去供电,可以实现无缝切换。
