The invention provides a locomotive power supply control method and an electric locomotive, and relates to the technical field of electric railway vehicles. The locomotive power supply control method comprises the following steps: controlling a standby power supply of which the output voltage is equal to that of a first mobile power supply to be connected to a driving system in parallel with the first mobile power supply; controlling the first mobile power supply to be disconnected from the driving system; controlling the output voltage of the standby power supply to be increased to be equal to the output voltage of the second mobile power supply; controlling the second mobile power supply to be connected to the driving system in parallel with the standby power supply; controlling the standby power supply to be disconnected from the driving system. The electric locomotive provided by the invention can execute the locomotive power supply control method. According to the locomotive power supply control method and the electric locomotive, the technical problem that the service life of components in a circuit is shortened due to the fact that stable connection is difficult in the locomotive power supply switching process in the prior art can be solved.

    本发明提供了一种机车电源控制方法及电动机车,涉及电动轨道车辆技术领域。该机车电源控制方法包括:控制输出电压与第一移动电源的输出电压相等的备用电源以并联于第一移动电源的方式接入行驶系统;控制第一移动电源与行驶系统断开;控制备用电源的输出电压提升至与第二移动电源的输出电压相等;控制第二移动电源以并联于备用电源的方式接入行驶系统;控制备用电源与行驶系统断开。本发明提供的电动机车可以执行上述的机车电源控制方法。本发明提供的机车电源控制方法及电动机车可以改善现有技术中机车电源切换过程中难以稳定衔接导致电路中元器件使用寿命降低的技术问题。
