Resrarch And Realization Of Wind Farms Booster Station Site Selection System Based On 3D GIS

The site selection of the booster substation affects the electric power output of wind farm and the overall construction quantity of wind farm.It is of great economic significance to site selection in wind farm construction.The traditional siting scheme is time-consuming and easy to be disturbed by human error,and it is difficult to adjust according to different selection schemes.A fuzzy hierarchical analysis model is proposed to verify the location of the existing wind farms booster substation in the virtual geographical environment in this paper.The site selection process is transformed into an automatic and visual analysis process in 3D GIS.The main research work and research results of this thesis are as follows:(1)The influence factors of the site selection in the site selection of the wind power station are summarized,and the influence criteria of the five different areas are constructed.The hierarchical analysis of the influencing factors and siting criteria was established,and the influence factors of siting were carried out by the index layer,criterion layer and target layer.(2)On the basis of the establishment of the hierarchical analysis system,the evaluation criteria of different siting factors are set up in the virtual geographical environment.(3)Based on the description and spatial analysis capability of spatial location and topological relation of 3d GIS,the process of the calculation system of site selection is determined.The selection of rough siting options and rules are set up to obtain a number of options for the rough site selection of the wind power station.Finally,the fuzzy hierarchical analysis model for the site selection of the integrated 3d GIS booster station is constructed.Based on the evaluation of the membership vector,the site selection evaluation and the visualization of the site selection are realized.In this paper,the wind farm in Sichuan and Shanxi has been constructed as experimental data to verify the accuracy of the method and the high efficiency of the site selection system.The quantitative analysis and visual expression of various evaluation index factors of wind farm are carried out respectively.The simulation results show that 3d GIS provides sufficient geographical information resources for the analysis of the results of wind farm site selection,and visually presents the site selection in a visual way.This method largely avoids the waste of time and financial resources caused by traditional artificial site selection.
