The invention relates to an unmanned aerial vehicle wind power detection dynamic path optimal planning method and system. The method comprises the following steps: determining a visual area and a visual point of an unmanned aerial vehicle on the surface of a wind turbine generator; finding out a path which is barrier-free, shortest and lowest in loss between visible points, and converting a path planning problem (IPP) into a traveling salesman problem (TSP); an improved discrete particle swarm optimization (DPSO) algorithm is adopted to solve the TSP problem, and an optimal path is planned; according to the method, the shutdown maintenance time of the wind turbine generator can be shortened as much as possible, economic losses caused by wind curtailment are reduced, meanwhile, dependence on the technology of operators is reduced, and high practicability is achieved.
