Aiming at the problem that the current distribution automation grounding fault detection effect is not good, a distribution automation grounding fault detection method based on fault dictionary method is proposed. Combined with the fault dictionary method, some fault states of distribution network are identified, the evaluation index system and algorithm of partial fault risk level of distribution network are constructed, some fault areas of distribution network are located, and the detection steps of partial fault states of distribution network are improved. Finally, it is confirmed by experiments. The detection method of distribution automation grounding fault based on fault dictionary method has high practicability and fully meets the research requirements.
