中文摘要	针对光伏组件风荷载及其体型系数的取值,通过以风洞试验为主结合数值计算的方法,对光伏组件支架单元进行风场特性研究,阐明各种因素(光伏组件倾角、高度、间距、方阵中的位置等)对其风荷载体型系数的影响规律,提出考虑各影响因素的风荷载计算公式。结果显示:光伏组件所受风荷载对其倾角变化敏感,随着倾角的增大而增大;光伏组件所受风荷载(正、负压差值)在靠近来流上游处最大,方阵边缘处较大,向下游发展逐渐变小;通过试验对光伏组件风荷载有关的各影响因素进行参数化,推导出其风荷载计算公式并给出算例,可为太阳能光伏结构的抗风设计提供参考。
英文摘要	The wind load of PV power station located in the desert gobi or the open land terrain plays an important role in the design of the support bracket and foundation for PV modules. The exact selection about the shape coefficients and wind load has a direct effect on the safety of the support and foundation. The effect of inclination angle,height, spacing, location in the PV array of PV modules on the wind load and shape coefficient was researched based on wind tunnel test and numerical simulation. Then the wind load calculation formula considering the influence of all factors was put forward. The results show that wind load suffered by PV module is sensitive to change of inclination angle,which increases as the inclination angle increases; The wind loads suffered by PV module (positive and negative difference) is the largest in the position close to upstream flow, is larger at the edge of array,and becomes gradually smaller in the downstream; The influence factors of wind loads on PV modules are parameterized,the wind loads formulae are derived and examples are given,which can supply the reference for wind resistant design of PV structure.
