摘　　要：本文总结了一套光伏方阵串并联失配损失的测试方法 ;以广东某5.5MWp分布式光伏发电系统为例,现场抽测了4组20块组件串联成为一个组串后的串联失配损失和10个组串并联接入一台汇流箱后的并联失配损失,最大值分别为1.64%和0.92%,证实了此方法的可操作性;对结果进行分析,提出了减小串并联失配损失的方法,对提高光伏发电系统的发电量具有重要意义。This paper summarizes a set of photovoltaic array series parallel test method of loss distribution;in Guangdong,a 5.5MWp distributed photovoltaic power generation system as an example,on-site sampling tests and 4 groups of 20 pieces of components are connected in series into a group on the series lost with loss and 10 groups on parallel access to a junction box after the parallel mismatch loss,maximum value respectively 1.64% and 0.92%, confirmed the this method of operation;to analyze the results of the proposed decrease on parallel loss of loss distribution approach,and it has important significance to improve the photovoltaic power generation system of generating capacity.
