目前地面光伏电站支架结构计算中方阵风荷载按照GB50797-2012《光伏电站设计规范》规定进行，即体型系数取1.3(单坡屋盖)，对于集中式光伏电站区域面积大、场地开阔、方阵结构简单、布置整齐、属大型群体类结构.根据国外光伏电站一些资料介绍及GB50009《建筑结构荷载规范》中局部体型系数有关规定，地面光伏电站不同区域如角部，北边(后排)，南边(前排)，东西边部，中间区域其不同位置体型系数不同的.基于以上情况，对于地面光伏电站支架结构按一种体型系数设计会造成成本不必要的浪费，故对地面光伏电站各区域体型系数的大小及不同区域体型系数分布进行研究测试十分必要.通过风洞试验来模拟确定地面光伏电站太阳能板阵列表面风压力在电站场内不同区域分布特征，确定阵列各分区用于设计的风荷载推荐值.
