The embodiment of the invention provides a power distribution network feeder automation fault processing method and system, and an electronic device, which can realize rapid and stable processing of line faults, and are high in reliability. The method comprises the following steps: arranging magnetically controlled switches among a plurality of sections of a feeder line for connection to form a multi-stage difference; monitoring a wireless communication state among the plurality of magnetically controlled switches; when the wireless communication state is normal, cooperative control is carried out on the plurality of magnetically controlled switches, and fault isolation is carried out on a fault section in the feeder line; and when the wireless communication state is abnormal, performing cooperative control on the plurality of magnetically controlled switches according to a stage differential closing control strategy, and performing fault isolation on a fault section in the feeder line. The system comprises a
