摘　　要：为了研究太阳能光伏阵列在单列布局下表面风压分布相互干扰作用,基于大气边界层理论和计算流体动力学的基本原理,利用流体动力学分析软件FLUENT对光伏阵列在单列6行布局0°和180°风向角下的表面风压分布特性进行CFD数值计算分析,通过表面平均风压系数和干扰因子,对比单个太阳能光伏板,探讨与分析了光伏阵列群体之间的风力相互干扰作用。研究表明:光伏阵列群体之间具有明显的遮挡效应,遮挡效应最为显著的是第二排光伏阵列,从第三排开始,光伏阵列平均风压系数变化趋于稳定,遮挡效应随着间距S_(y)的增大逐渐减弱,这为光伏结构在风荷载作用下优化和精细化设计提供理论依据。In order to study the interaction of wind pressure distribution on the surface of solar photovoltaic arrays in single column layout,based on the fundamental principles of fluid dynamics and the theory of atmospheric boundary layer,the surface wind pressure distribution characteristics of photovoltaic arrays in a single row 6 layout at 0°and 180°wind direction were analyzed by CFD numerical calculation using Fluent software.Compared with individual solar photovoltaic panel,the wind interaction between photovoltaic arrays were discussed and analyzed by means of surface average wind pressure coefficient and interference factor.The results showed that:there is an obvious shielding effect between photovoltaic arrays,the second row photovoltaic array has the most significant shielding effect,starting from the third row,the average wind pressure coefficient of photovoltaic arrays tend to be stable,as the spacing S_(y)increases,the shielding effect gradually decreases,this provides a theoretical basis for the optimization and fine design of photovoltaic structures under wind load.
