摘要
规模光伏阵列在运行中经常受阴影影响,从而使整个光伏发电系统效率下降。归纳了光伏阵列故障形成的原因,分析了目前光伏阵列的故障诊断方法,通过对现有方法优缺点进行总结,可知基于电特性检测故障的诊断方法最具有工程应用潜力,同时提出基于电特性检测方法亟需解决的两个问题。
Scale photovoltaic （PV） array is often influenced by shadow, so the system efficiency is declined.The causes of PV array fault are organized,and the fault diagnosis methods of PV array are analyzed.The fault diagnosis method based on electrical character of PV array is considered has the potential application in PV system project through analyzing the merits and defects in each method, and two key problems of this method are also proposed. Keywords ： photovoltaic array ; fault diagnosis ; electrical character
