摘　　要：光伏组件的匹配性研究一直是提高光伏电站发电效率的重点研究方向,现有的研究途径只是通过数据模型或独立的测试仪器进行,结果具有较大的不确定性,失配损失的指标一直没有得到较好检验。该文将通过一种多通道伏安特性测试系统设备研究,实现组串内串联匹配损失特性的自动快速测试,较好地达到对串联失配指标的验证。The matching of photovoltaic modules has always been the key research direction to improve the generation efficiency of photovoltaic power stations.Existing reaserch approaches are conducted only through data models or independent testing instruments.The results are highly uncertain.The index ofmismatch loss has not been well tested.In this paper,a multi-channel test system is developed.Realize automatic and fast test of matching loss characteristics in group series,the series mismatch index is verified.
