针对光伏阵列不同拓扑结构在故障应对能力方面存在的差异,开展局部遮阴、短路故障、开路故障以及组件老化等4种典型故障下,13种不同拓扑结构的输出特性对比分析,并结合港口、山区和戈壁等不同场景的特点,提出光伏阵列拓扑结构优化建议。结果表明,以最大输出功率点功率作为评价指标,局部遮阴、短路故障以及开路故障下最优的结构分别是全交叉结构（TCT）、串并联结构（SP）、TCT结构。同时,在组件有老化的情况下,拓扑结构在不同故障下的输出特性变化未引起显著差异。进一步综合分析,认为在港口环境下最适合的拓扑结构是SP结构与桥式结构（BL）,在山区环境最适合的是串并联-全交叉结构（SP-TCT）,在戈壁与沙漠的环境最适合的是BL-TCT结构。
Abstract
In response to the differences in fault response capabilities among different topology structures of PV arrays, the output characteristics of 13 different topology structures are analyzed under four typical faults： partial shading, short-circuit fault, open-circuit fault, and component aging. Based on the characteristics of different scenarios such as ports, mountainous areas, and the Gobi and desert, optimization suggestions for PV array topology structures are proposed. The experimental results show that using the maximum power point output as the evaluation index, the optimal structures under local shading fault, short-circuit fault and open-circuit fault respectively are TCT structure, SP structure and TCT structure. At the same time, when the components are aging, the changes in the output characteristics of the topology under different faults show no significant differences. After further comprehensive analysis, it is believed that the most suitable topology structures in the port environment are SP structure and BL structure, the most suitable topology structure in mountainous environment is SP-TCT structure, and the most suitable topology structure in the Gobi and desert environments is BL-TCT structure.
