摘　　要：该文通过数学建模研究雾霾相对湿度和质量浓度对辐照度的影响规律,并通过实验验证雾霾的相对湿度和质量浓度对辐照度和光伏组件输出功率的影响规律。实验结果表明:雾的相对湿度(RH)从23%上升至90%,辐照度下降52.17%,光伏组件输出功率下降46.5%,在相对湿度达到65%之后辐照度和功率下降幅度加快;霾质量浓度从18µg/m^(3)增加至517µg/m^(3),RH=30%、50%、60%、75%、80%、90%时辐照度分别下降16.0%、25.0%、40.0%、74.4%、73.1%、68.6%,光伏组件输出功率分别下降21.8%、22.5%、35%、69.9%、70.1%、67.7%;RH从30%增加至90%,霾质量浓度为108、189、312、405、497µg/m3时辐照度分别下降60.0%、78.8%、800.%、85.1%、85.8%,光伏组件输出功率分别下降47.4%、73.3%、78.1%、82.5%、84.9%,随着RH的增大辐照度和输出功率的降幅在逐渐增大。关于雾的相对湿度和雾霾质量浓度对辐照度的影响进行数值模拟,模拟结果和实验结果基本吻合,模拟和实验误差最小为0.1%,最大为10.7%。In this paper,the influence of relative humidity and mass concentration of haze on irradiance and output power of photovoltaic modules is studied by mathematical modeling,and the influence law is verified by experiments.The experimental results show that the relative humidity of fog increases from 23%to 90%,the irradiance decreases by 52.17%,and the output power of photovoltaic module decreases by 46.5%.When RH(relative humidity)is more than 65%,the irradiance and power dedine are.When the haze mass concentration increases from 18μg/m^(3) to 517μg/m^(3),when RH=30%,50%,60%,75%,80%and 90%,the irradiance decreases by 16%,25%,40%,74.4%,73.1%and 68.6%,respectively.The output power of photovoltaic modules decreases by 21.8%,22.5%,35%,69.9%,70.1%and 67.7%,respectively.When the haze concentration is 108,189,312,405μg/m^(3) and 497μg/m^(3),RH increases from 30%to 90%,the irradiance decreases by 60%,78.8%,80%,85.1%and 85.8%,respectively.The output power of photovoltaic modules decreased by 47.4%,73.3%,78.1%,82.5%and 84.9%,respectively.The irradiance and output power decrease gradually with the increase of RH.The effects of relative humidity and haze concentration on irradiance are numerically simulated.The simulation results are basically consistent with the experimental results.The minimum error between simulation and experiment is 0.1%,and the maximum error is 10.7%.
