Fault processing method and device of power distribution network, electronic equipment and medium

The invention discloses a fault processing method and device for a power distribution network, electronic equipment and a medium, and the method comprises the steps: obtaining an updated feed line group graph set of the power distribution network and a graph model file of the feed line group graph set, and enabling the feed line group graph set to comprise a feed line group looped network graph and a feed line single line graph; when the graph model file meets a graph model verification condition, determining power distribution network level information of the feeder group looped network graph and corresponding automation mode information; and according to the power distribution network level information, the automation mode information and a preset machine learning model, carrying out fault positioning and isolation on a fault of the power distribution network. Through the improved feeder group looped network diagram based on the power distribution network full-contact topological relation, the topological h
