Optimization algorithm for effectively realizing automatic fault isolation and power supply recovery of power distribution network

The invention relates to an optimization algorithm for effectively realizing automatic fault isolation and power supply recovery of a power distribution network, and belongs to the technical field of power distribution network fault recovery. The method comprises the following specific steps: firstly initializing a power distribution network, then isolating a fault from each transformer substation by judging whether the transformer substation is connected with a fault line F, then searching a current electrified subsystem and a current non-electrified subsystem, then judging a set Y in the step S3, selecting one line from the set Y, and finally selecting one line from the set Y; checking whether the potential feasible connection lines are communicated with the nodes connected with the fault lines or not until all potential feasible connection lines are excluded; finally, testing is carried out on the faulty feeder system, faults are automatically, rapidly and optimally isolated by turning on and turning off e
