为了解决光伏阵列在局部阴影遮蔽条件下引起其输出特性发生变化，从而导致光伏发电效率降低等问题，基于光伏电池物理特性模型，利用数值模拟方法分析了阴影遮蔽条件下阴影数目、深度、分布及温度系数等因素对光伏阵列输出特性的影响。为实现光伏阵列的最大功率输出，提出了在阴影遮蔽条件下光伏阵列结构的优化配置规则，并给出了设计案例，结果证明可重构优化配置方法可以有效改善光伏阵列输出特性，提高了光伏发电系统的效率。

To address the photovoltaic (PV) array output characteristic change and reduced efficiency of PV generation system due to the partial shade condition,a numerical model-ing method based on the PV cell characteristic is used to analyze the PV array output characteristics variation under the different conditions including shade area distribution and temperature coefficient effect. Moreover,in order to achieve the maximum output power,a reconfigurable optimization arrange-ment method of PV array in the partial shade condition is presented. The optimization arrangement rules of the PV array are also discussed. Finally, the instances of the PV array reconfigurable optimization arrangement are given. The results indicate that the reconfigurable optimization arrangement method can effectively improve PV array output characteristic and increase the efficiency of the PV generation system.
