摘　　要：提出工程适用的光伏阵列和逆变器损耗模型，基于江苏光伏发电监测系统平台，研究多个光伏电站的运行监测数据，总结出光伏电站运行特性规律，根据光伏电站系统结构提出光伏系统效率理论计算方法，归纳光伏电站系统效率为80．2％。90．4％，验证理论分析的正确性和有效性，提出光伏电站送出线路可按装机容量80％进行导线截面选择，可提高资产利用效率。An engineering analysis method based on the model of energy loss for photovoltaic array and inverter was proposed in this paper. The operating data of several PV plants is researched applying the PV Power Generation Monitoring System of Jiangsu Province, and the characteristics are concluded. The theoretical calculation method of photovoltaic system efficiency according to the PV stations＇ system structure is deduced. The quantitative analysis clarifies that the PV stations＇ system efficiency is within the range of 80.2%-90.4%. In addition, based on the data of Jiangsu PV generation system platform, the validity and correctness of the theoretical analysis through statistical analysis is verified. The conductor＇s cross section of the PV stations＇ output line being selected according to 80% of the installed capacity will save investment and improve asset utilization efficiency.
