The invention belongs to the field of rail transit, and provides a train high-voltage power supply system fault processing method, a controller, a train and a medium, firstly, high-voltage and traction system faults are classified into three levels, namely a serious fault, a medium fault and a slight fault, and whether the high-voltage power supply system has a fault or not is judged; and in response to a fault of the high-voltage power supply system, obtaining a fault line interval, and taking corresponding protection measures according to the fault type, the fault line interval and the fault grade of the fault type. Through the train high-voltage power supply system fault processing method, when a traction system fault and a high-voltage system fault occur in the train operation process, fault information can be automatically recognized, effective protection measures can be taken, fault equipment can be cut off, and an intelligent protection system of a train circuit breaker can be automatically closed, so that the risk of man-made misjudgment or misoperation is reduced; and the safety and reliability of the unmanned driving mode are improved.

    本发明属于轨道交通领域,提供了列车高压供电系统故障处理方法、控制器、列车和介质,首先对高压和牵引系统故障进行分级,所述故障分级为严重故障、中等故障、轻微故障三级,判断高压供电系统是否发生故障;响应于高压供电系统发生故障,获取故障线路区间,根据故障类型、故障线路区间和该故障类型所处的故障分级采取相应的保护措施。通过列车高压供电系统故障处理方法,当列车运行过程中发生牵引系统、高压系统故障时,能够自主识别故障信息,采取有效的保护措施,切除故障设备,自动闭合列车断路器的智能保护系统,降低了人为误判或操作失误的风险,提高了无人驾驶模式的安全可靠性。
