为了精确预测真实气象条件下光伏组件瞬态温度场,提出一种基于能量平衡法的光伏组件瞬态温度场预测方法,该方法构建了真实气象条件下光伏组件温度场数值计算的有限差分模型,并基于实际测量的气象条件预测了阴雨和多云两种天气下光伏组件温度场,通过与文献实测值比较,两者平均相对误差分别为1.63%和1.16%,表明本研究所开发的预测模型完全可以用于任何气象条件下光伏组件的瞬态温度场预测,相比于以往的预测模型,该模型具有更加准确快速的预测能力与更好的适用性。

In order to accurately predict the transient temperature field of photovoltaic modules under real meteorological conditions,a method for predicting the transient temperature field of photovoltaic modules based on the energy balance method was proposed in this paper.The method built a finite difference model for the numerical calculation of the temperature field of photovoltaic modules under real weather conditions,and predicted the photovoltaic temperature field based on the actual measured meteorological conditions under rainy and cloudy weather.The average relative errors of the two were 1.63%and 1.16%respectively by comparing with the measured values in the literatures,which indicate that the prediction model developed in this study can be used to predict the transient temperature field of photovoltaic modules under any meteorological conditions.Compared with previous prediction models,this model has more accurate and rapid prediction capabilities and better applicability.
