The invention relates to the field of electric locomotives, and provides a locomotive unpowered loopback control method, system and device and a medium, and the method comprises the steps: obtaining user operation, and entering unpowered loopback according to a preset entering condition and the user operation; a power battery is put in, an auxiliary power supply is started to supply power to auxiliary equipment, and a TCU controls closing of a 2-axis isolation contactor and a 5-axis isolation contactor; switching power supply modes according to the working conditions; and exiting the unpowered loopback according to a preset exit condition and the user operation. According to the locomotive, an extra return power generation device does not need to be added to carry out excitation treatment on the motor, meanwhile, it is guaranteed that the locomotive can supply power to an auxiliary system of the locomotive on the premise that the pantograph does not rise and a main breaker is closed within the full running speed range of the locomotive, and the comfort of crew members is improved.

    本发明涉及电力机车的领域,本发明提出了一种机车无动力回送控制的方法、系统、设备及介质,方法包括:获取用户操作,根据预设的进入条件和用户操作进入无动力回送;动力电池投入,启动辅助电源,给辅助设备供电,TCU控制闭合2、5轴隔离接触器;根据工况切换供电模式;根据预设的退出条件和用户操作退出无动力回送。本发明的机车无需增加额外的回送发电装置来对电机进行励磁处理,同时也保证了在机车运行全速度范围内,机车均可以在不升弓,闭合主断前提下,给机车的辅助系统供电,提高了乘务人员的舒适性。
