摘要

光伏并网逆变器是光伏发电系统的核心部件，其性能的优劣直接关系到整个电站的发电效率。目前，逆变器的性能检测基本上都是在标准实验室环境下进行的，缺乏实际发电运行环境下的性能检测。本文针对逆变器在实际运行环境中存在的问题，构建了光伏并网逆变器入网检测平台，提出了逆变器户外测试方案。实验表明，该测试平台可实现对光伏逆变器实际性能指标的检测与分析，具有较好的合理性和有效性，可以用于光伏并网逆变器的户外实证性测试。

Abstract

Photovoltaic grid-connected inverter is the core component of photovoltaic power system, which performance directly affects power generation efficiency of the whole power station. At present, the inverter performance test is usually operated under the standard laboratory condition, but it is short of real-time and real-environment testing condition. Aiming at the problems of inverter existing in practical operating, a detection platform of grid-connected inverter is constructed, and testing scheme for inverter existing in practical operating is proposed. The results show that actual performance index of photovoltaic inverter can be detected and analyzed, which is reasonable and effective, and can be used in outdoor testing techniques for photovoltaic grid connected inverter.

Key words： photovoltaic grid-connected inverter; power generation efficiency; performance test; laboratory condition; outdoor testing techniques
