煤矿采动区风电场风机选址方法研究

当风电场建设位置选择在煤矿采动影响区范围以内时,新建风机会受到煤层开采的影响,为了在场地内选择出最合适的风机建设位置,采用地表变形预计的方法,计算出煤层开采最不利情况下的地表移动变形情况,文中通过场地的稳定性分析,最终确定新建风机的位置。结果表明:建设在煤矿采动区上方的风机除了满足基本的风能资源需求以外,必须考虑煤矿煤层开采的影响;根据计算煤层开采最不利情况下风机的倾斜变形结果来调整新建风机位置。按照该方法确定的风机位置可以满足采动影响区风机建设工程的要求。

Study on the wind turbine site selection method of the wind farm in coal mining area

When the construction location of the wind farm was within the scope of the coal mining influence area,the new wind turbine would be affected by the coal mining.In order to select the most suitable wind turbine construction location in the site,the surface deformation prediction method was used to calculate the surface movement and deformation under the most unfavorable situation of the coal mining.Through the stability analysis of the site,the location of the new wind turbine was finally determined.Results showed that the wind turbine built above the mining area of the coal mines must meet the basic needs of the wind energy resources,and the influence of the coal mining must be considered.Position of the new wind turbine should be adjusted according to the results of inclined deformation of the wind turbine under the most unfavorable conditions of the coal mining.Wind turbine location determined by this method could meet the requirements of the similar wind turbine construction projects.
