The invention discloses a power supply control method and system for a train during a single-pantograph fault, a controller and the train, and the power supply control method for the train during the single-pantograph fault comprises the following steps: judging whether the train has the single-pantograph fault, if yes, controlling a high-voltage contactor connected between the output sides of two pantographs to be closed, otherwise, controlling the high-voltage contactor to be in an off state. The method for judging whether the train has the single-pantograph fault comprises the following steps: when two auxiliary inverters on the train obtain auxiliary power supply and high-speed circuit breakers corresponding to two traction units on the train are closed, detecting whether the two traction units on the train obtain traction power supply, and when the detection result is that only one traction unit obtains the traction power supply, judging that the train has the single-bow fault. According to the method, normal operation can be realized without losing any traction performance when the train has the single-bow fault; when a vehicle passes through different power supply sections, circuits of the different power supply sections cannot be directly short-circuited, and vehicle operation safety is guaranteed.

    本发明公开了一种单弓故障时列车的供电控制方法、系统、控制器及列车,其中单弓故障时列车的供电控制方法包括:判断列车是否发生单弓故障,若是,则控制接在两受电弓输出侧之间的高压接触器闭合,否则控制高压接触器维持在断开状态。判断列车是否发生单弓故障的方法包括:在列车上两个辅助逆变器均获得了辅助供电,并且列车上两套牵引单元对应的高速断路器均闭合时,检测列车上两个牵引单元是否获得牵引供电,当检测结果为有且仅有一个牵引单元获得了牵引供电时,判断列车发生了单弓故障。本发明在列车单弓故障时能够实现不损失任何牵引性能而正常运行;在车辆通过不同供电段时不会将不同供电段电路直接短接,保证车辆运行安全。
