摘要
采用Fluent软件中的RANS模型求解N-S方程以模拟光伏场区流场,开展沙漠地区光伏电站内光伏阵列对流场和地表切应力分布研究.分析了不同风向下多排光伏阵列的流场及地表切应力分布规律,进而讨论了光伏阵列形成保护区的特征及沙漠光伏电站内须加强抗风蚀区域.结果表明:不同风向对应的光伏场内的流场显著不同,±90º风向时的不同主要体现在光伏电场周围区域,保护区面积较大;±45º风向时光伏板阻风效应明显降低,且保护区范围缩小.可根据当地主要风向确定防沙的重点区,为沙漠光伏电站防风固沙高效低成本设计提供参考.
Abstract
A simplified flat surface photovoltaic array model was established,N-S equation was solved by RANS model in Fluent software to simulate the photovoltaic field flow field,and the photovoltaic array flow field and surface shear stress distribution in photovoltaic power stations in desert areas were studied.The flow field and surface shear stress distribution of multi-row photovoltaic arrays under different wind direction were analyzed,and the characteristics of protected area formed by photovoltaic arrays and the areas that need to strengthen wind erosion resistance in desert photovoltaic power stations were discussed.The results show that the flow field in PV field is significantly different with different wind direction,and the difference is mainly reflected in the area around photovoltaic field when the wind direction is±90º,and the protected area is large.When the wind direction is±45º,the wind blocking effect of the photovoltaic panel is significantly reduced,and the scope of the protected area is reduced,so the key areas of sand prevention can be determined according to the local main wind direction.It can provide reference for the high efficiency and low cost scientific design of desert photovoltaic power station wind prevention and sand fixation.
