风沙环境下光伏板表面积尘仿真及其透光率研究OACHSSCDCSTPCD
Simulation Study of the Dust deposition on Photovoltaic Panel and Its Light Transmittance in the Wind-blown Sand Environment
通过流体动力学仿真方法,研究了风沙环境下不同倾角光伏电池板表面的积尘问题,基于此讨论了不同安装倾角光伏板透光率的衰减程度.结果表明,光伏板表面沙尘沉积量随着空气中沙尘体积分数和粒径的增大指数增加;随着光伏板安装倾角的增加,沙尘沉积量先上升后下降,在倾角为50°时板上沉积量达到最大,积尘光伏板的透光率呈现相似的变化规律.本文结果对于荒漠化地区光伏电站的建设及其安全运行具有重要参考价值.
Based on the fluid dynamics simulation,the dust deposition on the photovoltaic panel with different inclinations was studied,and the attenuation degree of light transmittance of photovoltaic panels was discussed.The results show that the dust accumulation on the photovoltaic panels increases exponentially with the increase of the volume fraction and size of dust in the air.As the installation angle of photovoltaic panel increasing,the amount of sand deposition is increased firstly and then decreased.The light transmittance of dust photovoltaic panel presents a similar change rule.These results proposed in this paper have important referencce value for the construction and safe operation of photovoltaic power stations in desertification areas.
