Intelligent auxiliary distribution automation master station FA fault studying and judging method

The invention relates to an intelligent auxiliary power distribution automation master station FA fault studying and judging method, which comprises the following steps: by taking a power distribution automation system, a front-end system and an intelligent terminal as a basic environment, sending a fault signal by a line, judging whether real-time current exists in the front-end system and the power distribution automation system, and processing a fault. A dispatcher obtains the real-time current value of the intelligent terminal through a remote measurement or remote signaling command, and the real-time current value is combined with the FA fault research and judgment module to judge whether the fault of the power distribution network line is correct or not. According to the implementation of the invention, the main station measures the current when the fault occurs through one key for the analysis of the dispatching personnel, whether the fault occurs truly or not can be judged according to whether the fau
