A ground fault locating method for a power distribution network includes: monitoring each phase line of three phase distribution lines, and in the event of occurrence of waves with fault features, performing wave recording to obtain phase line record files; combining the record files corresponding to each of the three phase lines to obtain fault record files; and synthesizing the fault record files to form a transient record file, determining a fault location according to a wave having a maximum change in wave amplitude between two points in the transient record file, and displaying the fault location in a wiring diagram. The ground fault locating method for a power distribution network can significantly improve accuracy of single-phase ground fault detection.
