摘要
针对不同的并网逆变器控制算法分别进行了研究。阐述了光伏并网逆变器的拓扑结构及工作原理,分析了各自的优缺点。利用Matlab软件建立模型,仿真实验结果表明,无差拍控制目前是并网逆变器最合适的控制方案。
Diverse control strategies of grid-connected inverter were studied respectively.The topology structure and work principle of inverters for grid-connected PV system were expounded,and some control strategies of photovoltaic grid-connected inverter were analyzed and compared.The Matlab simulation model was established.The results show that the deadbeat control algorithm is at present the most suitable for photovoltaic grid-connected inverter.
