Power distribution network fault positioning method and system based on fault analysis

The invention belongs to the technical field of power systems, and particularly relates to a power distribution network fault positioning method and system based on fault analysis, and the method comprises the steps: monitoring the electrical parameters of a line in real time through a fault indicator installed on the line of a power distribution network, and triggering the fault indicator to judge and send out an abnormal signal; based on the abnormal signal, acquiring an operation state parameter of the fault indicator, acquiring an operation state value of the fault indicator, and comparing an abnormal coefficient of the fault indicator with a preset abnormal coefficient; the control signal is generated, the position of the fault indicator is obtained according to the type of the control signal, corresponding processing measures are taken, the detection result of the fault detector can be accurately and intelligently judged in combination with the running state factor of the fault detector, and the problem
