摘要

光伏并网逆变器是光伏发电系统中的关键部件。文中通过分析使用欧洲效率、加州效率及中国效率3种指标评价在中国典型Ⅰ类辐照地区运行的光伏并网逆变器的效率所存在的片面性及不准确性，建立了针对光伏并网逆变器效率的评价模型。基于2016—2017年中国宁夏地区的气象数据，通过在模型中增加了不同光伏组件类型、环境温度、风速、最佳辐射倾角、2 min级的采样间隔等影响光伏并网逆变器在实际运行中性能的关键因素，得到了适合中国典型Ⅰ类辐照地区光伏并网逆变器的效率评价方式，为今后在该气候类型地区光伏电站建设中光伏并网逆变器的选型设计提供更加合理的评价指标，为准确反映光伏逆变器在实际运行中的发电量，更好地测试与评估光伏并网逆变器的发电性能提供参考。

Abstract

The grid-connected photovoltaic (PV) inverter is a key component in the photovoltaic power generation system. This paper analyzes the one-sidedness and inaccuracy of three evaluation methods

including European efficiency

CEC efficiency and Chinese efficiency evaluation indicators

for the efficiency of grid-connected PV inverters operating in the typical type-Ⅰ irradiation area of China. Then an evaluation model for the efficiency of grid-connected PV inverters is developed. Based on the meteorological data from 2016 to 2017 in Ningxia of China

the key factors affecting the performance of grid-connected PV inverter in the actual operation condition are considered in the model

including the types of PV components

ambient temperature

wind speed

optimal irradiance inclination angle

sampling interval of 2 min

etc. The evaluation method is suitable for typical type-Ⅰ irradiation area of China

which provides a more reasonable evaluation index for the selection and design of inverters in the construction of photovoltaic power plants in the area. And it also offers a reference to accurately reflect the power output of grid-connected PV inverter in the actual operation condition and evaluate its power generation performance.
