Taking a mountainous wind farm as the research object,based on the shortest path Dijkstra algorithm,with the shortest new road path and cable length in the wind farm field as the optimization goal,a route selection algorithm is established to meet the constraints of road longitudinal slope gradient,minimum turning radius,sensitive area,boundary and pile distance.The algorithm has the following characteristics.First,the regular triangular grid and the diagonal distance heuristic function are used to search six directions to meet the requirements of the minimum turning radius,which greatly improves the convenience of the algorithm.Secondly,the algorithm is divided into two steps.The first step is for the main road service,and the shortest path of the two points can be obtained when the start and end points of the road to be optimized are input.The second step is for the feeder road service.With the main road from the first step as the existing road,the shortest path of the distance from the main road to the end point can be obtained automatically when the coordinates of the feeder road end point(coordinates of tower locations)are input.The research results of this paper can provide important process guidance for the preliminary work of actual wind farm construction.
