摘要
本文提出一种基于伏安输出曲线仿真的光伏组串故障诊断方法.采用Matlab/Simulink软件,以光伏组件数学模型为基础,构建光伏组串故障分析模型.使用模型对存在灰尘沉积、阴影遮挡、组件功率衰减等问题组串伏安输出特性进行仿真,验证故障分析模型的准确性,并总结不同故障类型下组串伏安输出特性的变化规律.
In this paper,a new type of fault diagnosing method for photovoltaic(PV)module strings,based on simulated voltage-current output curves,was proposed.The model was built by using Matlab/Simulink software.I-V output curves of PV module strings,with dust deposition,shielding and PV module power degradation were simulated by using the diagnosing model.The accuracy of the model was verified,and the variation of the output characteristics of group strings with different fault types was summarized.
