非正常功率衰减光伏组件的发电量分析与研究

STUDY ON POWER GENERATION OF ABNORMAL POWER DEGRADATION PV MODULE IN PV POWER STATION

光伏组件是光伏电站的关键部件,其功率衰减将造成光伏电站的整体发电量下降,影响电站的效益。通过对连接有正常功率衰减光伏组件和非正常功率衰减光伏组件的2台逆变器的发电量数据进行分析,得出了非正常功率衰减光伏组件的衰减规律及衰减程度,可为以后深入研究提供参考。

PV module is the key component of PV power station.The power degradation of PV module will cause the overall power generation of PV power station to decrease,which will affect the benefits of power station.This paper analyzes the power generation data of two inverters connected with normal power degradation PV modules and abnormal power degradation PV modules,so as to obtain the degradation law and degree of abnormal power degradation PV modules,and provide reference for further research in the future.
