The invention discloses a train power supply method, system and device and a train, and relates to the field of rail transit. In the scheme, whether the train travels to a conversion area or not is judged according to a received mark signal, if yes, the voltage output to an intermediate direct current loop by a standby power supply module is controlled to be within a preset range of the voltage output to the intermediate direct current loop by a main power supply module, and the conversion area is an area before the train travels to a non-power area. According to the application, before the main power supply module cannot supply power to the traction module, the power supply of the traction module is switched to the standby power supply module, so that when the train runs to the non-power area, the standby power supply module can normally supply power to the traction module; seamless switching between the power supply modules can be achieved, the step of controlling the main power supply module to be closed or the standby power supply module to be opened does not exist, the switching process is smooth, and operation can be conducted on a large ramp or a frequent non-power area.
本申请公开了一种列车供电方法、系统、装置及列车,涉及轨道交通领域。该方案中,根据接收到的标志信号判断列车是否行驶至转换区,若是,则控制备用电源模块输出至中间直流回路的电压在主电源模块输出至中间直流回路的电压的预设范围内,其中,转换区为列车行驶至无电区前的区域。本申请在主电源模块无法为牵引模块供电之前,将牵引模块的供电电源切换为备用电源模块,从而在列车行驶至无电区时,可以使牵引模块被备用电源模块正常供电,此外,由于中间直流回路上一直存在电压,可以实现电源模块之间的无缝切换,不存在控制主电源模块关闭或者备用电源模块开启的步骤,切换流程顺畅,可以在大坡道或者较为频繁的无电区运行。
