摘要:
效率是衡量并网光伏逆变器工作性能最重要的指标之一,直接影响着系统的电力输出。文章首先对并网逆变器国内外评价方法进行了总结和对比,采用加权公式计算的转换效率能够较为真实地反映光伏逆变器在现场运行的效率;其次对我国太阳能资源带的划分进行了介绍,并以Ⅱ类资源带的尚义光伏电站为研究对象,对该电站每分钟采集的2012年6月1日至2013年5月31日数据进行统计分析,得出该地区太阳辐射变化规律,并通过对逆变器的数据统计分析得出了适用于该地区的逆变器转换效率加权公式,对于该资源带光伏电站建设具有一定指导意义。
Abstract:
Efficiency is one of the most important indicators for performance evaluation of grid-connected PV inverter, since it directly affects the power output. Firstly, the widely applied evaluation methods both at home and abroad were summarized and compared. It shows that by means of weighted method, the calculated conversion efficiency can emulate the PV inverters operating efficiency in the field more precisely. Secondly, the classification of solar energy resource belts of our country was described and SHANGYI Plant in class II was selected for this study. Through the statistical analysis of captured data per minute of the Plant from June 1, 2012 to May 31, 2013, the variation rule of regional solar irradiation was conducted. In addition, the weighted formula of inverter conversion efficiency was derived by statistical analysis of practical data from inverter. They have guiding signifciance of photovoltaic power plant construction.
