Two-stage reconstruction method for power distribution network of comprehensive power propulsion system of ship

The invention specifically relates to a two-stage reconstruction method for a power distribution network of a comprehensive power propulsion system of a ship. The method comprises the following steps of: (1) judging a power loss load; (2) performing shortest route search based on a breadth-first search strategy; and (3) Gray code cuckoo search. According to the method, a two-stage reconstruction strategy is proposed, problems of line recovery and load power supply recovery can be solved by using a shortest route search algorithm and a Gray code cuckoo search algorithm based on the breadth-first search strategy at different stages, the defect of complex calculation because of high coupling of an on/off state and load power supply in a conventional power distribution network reconstruction method can be avoided, and the power distribution network reconstruction efficiency can be improved.
