文章内容:针对风荷载在平单轴光伏阵列的干扰作用,对单排平单轴光伏支架和平单轴光伏阵列进行了刚性模型测压风洞试验。研究了倾斜角度和风向对气动特性的影响,阐明了平单轴光伏阵列风致干扰效应的基本特征。结果表明:当倾斜角度较小时,干扰效应较小,倾斜角度越大,干扰效应越强。从平均压力和扭矩系数来看,干扰效应主要表现为遮挡效应。基于压力和扭矩系数的波动,在小倾斜角和大倾斜角范围内,干扰效应分别表现为遮挡效应和放大效应。平单轴光伏阵列后排光伏组件的风荷载功率谱出现显著的频率峰值,且受风致振动的影响较前排太阳能组件更大。风向的影响导致风荷载沿平单轴支架长度方向分布不均匀,因此应考虑风向对光伏阵列边缘区域风荷载的增强作用。
