description The invention relates to a power distribution network grounding fault identification method based on near fault point calculation, and the method comprises the following steps: S1, when a single-phase grounding fault occurs in a power distribution network line, the zero-sequence voltage rises, and an intelligent edge calculation terminal at the head end of each line records the time scale of the fault moment, and transmits the fault occurrence moment t to all sensor centers under the line; s2, each sensor center sends the three-phase recording waveform at the fault moment to an intelligent edge computing terminal of the line; s3, the intelligent edge computing terminal synthesizes a zero-sequence current, and performs fault judgment based on a parameter identification method to directly position a fault section; s4, the intelligent edge computing terminal uploads fault section information to the power distribution automation master station; according to the invention, positioning and removal of faults and pow
