摘要

在全球新兴的光伏市场中,对并网光伏系统的运行性能进行适当的评估变得越来越重要。用于分析系统在能量输出、太阳能资源和系统损耗对其各组成部分影响方面性能的广泛使用的性能指标有总发电量、最终发电量/比发电量、性能比、PVUSA额定值和基于PTC交流功率与STC直流功率之比的性能指标。本文对43kw非晶硅薄膜光伏并网系统进行了性能分析。使用2011年7月至2014年7月的工厂监测记录数据进行分析。报告了近三年来遇到的主要运维问题。

Performance monitoring of 43 kW thin-film grid-connected roof-top solar PV system
In the emerging photo-voltaic markets worldwide the use of appropriate estimation of the operating performance of the grid-connected PV systems is becoming more and more crucial. The widely used performance indices that are used to analyze the system performance with respect to energy output, solar resource and the effect of system losses in its various components are total yield, final yield/specific yield, performance ratio, PVUSA rating, and performance indicator based on ratio of ac power at PTC to dc power at STC. This paper presents performance analysis of a 43 kW amorphous-silicon thin-film grid-connected PV system. Recorded plant monitoring data during July 2011 to July 2014 is used for the analysis. Major operation and maintenance issues encountered in last three years are also reported.
