Wind Power Network News: In recent years, the wind power industry has developed rapidly, and there are more and more wind farms in various places. Even in some areas with poor resources and difficult construction, there are wind turbines. In such areas, there will naturally be some limiting factors that affect the layout of wind turbines, thereby affecting the planning of the total capacity of the wind farm.
For mountain wind farms, there are many limiting factors, especially the influence of terrain, forest land, mining area and other factors, which may limit the layout of fans in a large range. In the actual project design, this situation often occurs: when the site is approved, it occupies forest land or presses ore, so that about half of the wind turbine points in the wind farm cannot be used, which seriously affects the construction of the wind farm.
In theory, how much capacity is suitable for development in an area is affected by various conditions such as local topographic conditions, resource conditions, and sensitive factors. Deliberately pursuing the total capacity will reduce the power generation efficiency of some wind turbines, thereby affecting the efficiency of the entire wind farm. Therefore, in the early stage of development, it is recommended to have a general understanding of the proposed site to confirm the potential factors that may affect the layout of the wind turbine in a large range, such as forest land, farmland, military area, scenic spot, mining area, etc.
After taking into account the sensitive factors, follow up the remaining wind farm area to estimate a reasonable planable capacity, which is of great benefit to the later wind farm design and wind farm profitability. The following is a calculation of the installed density of several projects planned by our company in mountainous areas, and then a more reasonable installed density of wind farms is analyzed.
The selection of the above projects is a relatively normal project, and the development capacity is basically close to the original development capacity, and there is no situation where it cannot be used in a large range. Based on the experience of the above projects, the average installed density in mountainous areas is 1.4MW/km2. Developers can make a rough estimate based on this parameter when planning the capacity and determining the scope of the wind farm in the early stage. Of course, there may be large forests, mining areas, military areas and other factors that may affect the layout of the wind turbines in advance.
