Intelligent Route Selection Method Of Wind Farm Road In The Mountain Based On Improved A~* Algorithm

With the continuous attention to ecological civilization construction and environmental protection,clean energy has a broader space for development.Wind energy,as a kind of clean energy with low development cost,has been widely used.How to efficiently complete automatic route selection under the premise of environmental protection,economy,and meeting the requirements of design indicators and specifications has become one of the research hotspots of wind farm road construction in the mountain.Based on the existing research foundation of intelligent route selection for mountain wind farms,this thesis analyzes the road design principles and design standards for mountain wind farms.And according to the vertical section design index in the road design standard for mountain wind farm,the calculation method of the longitudinal slope,the length of the longitudinal slope and the vertical curve angle is determined.Aiming at the characteristics of road construction in mountain wind farm route selection and the problem that the initial point and the target point are not reachable,the improved A~* algorithm suitable for intelligent route selection of wind farm road in the mountain is obtained.With ArcGIS as the main technical support,an intelligent route selection model of wind farm road in the mountain is established,which takes Manhattan distance as the heuristic function,and takes road longitudinal slope gradient,longitudinal slope length,vertical curve angle and forbidden obstacle allowed area as constraints.The permitted range of forbidden obstacles is used to restrain the linear elements of tin layer in ArcMap to optimize the road cost grid,and the improved A~* algorithm is used to optimize the route search efficiency.Based on the road network and traffic situation of a wind farm in Zhangjiakou,the experimental analysis of road line selection in wind farm is carried out on the road intelligent line selection model of mountain wind farm.Through the experimental analysis of the actual project,it is verified that the intelligent route selection model of wind farm road in the mountain has the function of route selection,and can be applied to the practical road selection problem of mountain wind farm.The intelligent route selection model of wind farm road in the mountain based on the improved A~*algorithm is beneficial to improve the efficiency of road route selection in mountain wind farms,and has reference value for the road construction of mountain wind farms.
