Fault type and fault section identification method

The invention discloses a fault type and fault section identification method, and the method comprises the steps of obtaining and storing the remote signaling transformation information of all switches in a power distribution network through responding to a tripping signal of a tripping device, thereby determining the fault type of a main switch or a branch switch according to the remote signaling transformation information, and further determining the fault type of the power distribution network. moreover, according to the remote signaling transformation information, determining a power supply side boundary and a load side boundary of a fault section of the power distribution network, so that the fault section of the power distribution network is determined. According to the fault type and fault section identification method, the fault type and the fault section of the power distribution network can be accurately identified, and the accuracy can be improved. 本发明公开了一种故障类型及故障区段识别方法，该方法通过响应于跳闸设备的跳闸信号，获取并保存配电网中所
