摘要
文章利用数值模拟结果分析了上游遮挡物对建筑物屋面光伏阵列风荷载特性的影响。分析结果表明:遮挡物对光伏阵列上的风荷载影响较大;随着遮挡物高度的增加,各光伏板受到的风荷载由升力逐渐转变为压力;当遮挡物与建筑物高度相同时,光伏板受到的风荷载最大,光伏板的最大体型系数约为0.37;遮挡物与建筑物间距的改变对各光伏板的体型系数影响较小。
The paper uses numerical simulation method to analyze the influence of upstream obstructions on the wind load characteristics of building roof mounted PV arrays. The analysis results show that the obstruction has a great influence on the wind load on the PV array;As the height of the obstruction increases, the wind load received by each photovoltaic panel changes gradually from lift to pressure. When the obstruction is the same height as the building, the wind load of the photovoltaic panel is the largest, and the maximum body shape coefficient is about0.37;The change of the distance between the obstruction and the building has little effect on the body shape coefficient of each photovoltaic panel.
