The invention relates to a train power supply control method and circuit, and the method comprises the steps: obtaining a first voltage difference of an energy storage power supply between two adjacent vehicles of a train when the energy storage power supply of the train carries out the parallel power supply, judging whether the first voltage difference is smaller than a preset voltage difference, and if yes, executing the step 1; if yes, a first contactor arranged between two adjacent vehicles of the train is controlled to be in a closed state; if not, a first instruction is sent out, and the first instruction is used for controlling traction power distribution of the energy storage power sources between the vehicles of the train, so that the second voltage difference of the energy storage power sources between the two adjacent vehicles controlled through the first instruction is smaller than the preset voltage difference; the vehicle is controlled to carry out power distribution and independent power supply at first, voltage regulation between two adjacent vehicles is achieved, the traction power limiting influence on the vehicle in the energy storage power supply voltage difference grid connection process can be reduced, and therefore the influence of energy storage power supply voltage difference grid connection on whole vehicle operation is reduced.
本申请涉及一种列车供电的控制方法及控制电路,方法包括:当列车的储能电源进行并联供电时,获取列车的相邻两节车辆之间的储能电源的第一电压差,判断第一电压差是否小于预设电压差,若是,则控制设置于列车的相邻两节车辆之间的第一接触器处于闭合状态;若否,则发出第一指令,第一指令用于控制列车的车辆之间的储能电源的牵引功率分配,以使得通过第一指令控制后的相邻两节车辆之间的储能电源的第二电压差小于预设电压差,在母线压差并网前,通过控制本节车辆先进行功率分配单独供电,实现相邻两节车辆之间的电压调节,能够降低储能电源压差并网的过程中,对车辆的牵引功率限制影响,从而减少储能电源压差并网对整车运行的影响。
