国核电力规划设计研究院 胡彬等：基于各向异性天空散射模型的光伏系统效率前排阴影遮挡损失系数计算方法
摘要
前排阴影遮挡损失修正系数是计算光伏电站系统效率的关键参数之一。本文基于Hay各向异性天空散射模型对前排阴影遮挡期间的光伏阵列表面太阳辐射强度变化规律进行了模拟，结合光伏电池片V-I特性建立了光伏阵列前排阴影遮挡工作模型。提出一种基于Hay各向异性天空散射模型和光伏电池片组串单元划分方式的光伏阵列前排阴影遮挡损失修正系数计算方法。该算法能够准确评估光伏阵列布置方式、接线方式、阵列间距、光伏组件规格、太阳辐射等因素对光伏电站系统效率的具体影响程度。为优化光伏系统方案，降低光伏电站损耗，提高系统效率提供了依据。
