3术语和定义

下列术语和定义适用于本文件。

3.1

组件风雪荷载设计值designvalueofwindandsnowloadformodule

在设计基准期内，为保证组件结构可靠性而对风荷载与雪荷载标准值组合后的等效荷载。

注：对应GB/T9535.1—2025中组件荷载设计值。

3.2

组件风雪荷载测试值testvalueofwindandsnowloadsformodule

组件风雪荷载设计值与安全系数的乘积，评估组件在户外载荷下结构机械性能和稳定性的荷载。

注：对应GB/T9535.1—2025中组件荷载测试值。

4基本规定

4.1光伏电站的光伏组件应按25年重现期确定基本风压和基本雪压。用于气象数据统计的风压和雪

压资料应符合GB50009—2012的相关规定，或按有关规范的规定采用。

4.2光伏组件表面的风压不均匀分布，采用二分区风荷载体型系数分布模型，作用在光伏组件的风荷

载体现为垂直于光伏组件板面的压力及绕光伏组件中心短轴的弯矩。

4.3阵风系数是瞬时风荷载与平均风荷载的比值，仅仅考虑瞬时变化的脉动风荷载，适用于支架刚性
