南京栖霞基地综合能源低碳示范区光伏系统发电量分析

Analysis of Photovoltaic System Power Generation in the Comprehensive Energy Lowcarbon Demonstration Area of Nanjing Qixia Base

针对已建成的综合能源低碳示范区光伏系统运行1 a多的发电量数据,进行了理论和实测的研究分析,理论分析包括组件衰减、逆变器适配损失、阴影遮挡、直流线损以及污秽损失等,实测分析包括组件红外及EL测试、组串I-V曲线、逆变器效率、直流线损和电能质量测试,并提出设计、安装及运维的指导建议。

Based on the power generation data of the photovoltaic system in the comprehensive energy low-carbon demonstration zone that has been in operation for over a year,theoretical and practical research and analysis were conducted.The theoretical analysis includes module attenuation,inverter adaptation loss,shadow shading,DC line loss,and pollution loss.The practical analysis includes module infrared and EL testing,string I-V curve,inverter efficiency,DC line loss,and power quality testing,and guidance suggestions for design,installation,and operation and maintenance are proposed.
