摘要
光伏并网发电系统具有造价低、输出电能稳定的优点,是光伏发电未来的主要趋势,而并网逆变器是并网光伏发电系统的核心装置。基于光伏并网逆变器的基本原理,提出了100 kW三相光伏并网逆变器系统设计方案。详细介绍了主回路关键元器件的选型与参数设计方法并提出了本系统的控制策略方案。样机实验结果表明,该逆变器设计合理、运行可靠、满足各项设计指标,具有很高的应用和推广价值。
Grid-connected PV system with the advantages of low cost, stable output power, is the main trend of the future of photovol- taic power generation, and grid-connected inverter is the core unit of grid-connected photovohaic power generation system. Based on the principle of the inverter, a 100 kW three-phase photovoltaic grid-connected inverter system design is proposed in this paper. It intro- duces the systemg control strategy programs and the parameters design method and selection of key components of the main circuit in de- tail. Prototype test results show that the inverter is designed reliable and it can meet all design specifications. It has high value in appli- cation and promotion.
