Self-healing method and device based on master station and voltage-time current cooperation

The invention discloses a self-healing method and device based on master station and voltage-time current cooperation, and the method comprises the steps: obtaining a distribution network feed line of a corresponding bus according to a power grid topological structure after a preset power grid protection mechanism acts, and enabling the distribution network feed line to comprise a feed line number; searching an effective section switch conforming to a preset switch state condition on the distribution network feeder line; after the effective section switch is found, determining the on-off state of an interconnection switch on a distribution network feeder line before the action of a preset power grid protection mechanism; executing a first preset recovery strategy based on section switch control on each distribution network feeder line where the effective section switch is located according to the feeder line number; and if the outgoing line tripping condition does not exist in the process of executing the fir
