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. 本发明具体涉及种船舶综合电力推进系统配电网络的两阶段重构方法。本发明包括：(1)判断失电负载；(2)基于宽度优先搜索策略的最短路径搜索；(3)格雷码布谷鸟搜索。本发明提出两阶段重构策略，分阶段采用基于宽度优先搜索策略的最短路径搜索算法和格雷码布谷鸟
