| 摘 要： | 文中设计了一种高性能的光伏并网群控系统装置.此装置包括光伏阵列板,多台并网逆变器和中央控制器.基于最大效率问题,光伏阵列板的设计为分布式连接,多台逆变器以链状控制法作为控制策略.在系统中各逆变器模决不完全相同情况下,此方法避免了环流的产生.最后通过仿真实验验证了上述方法的有效性,实验结果表明系统具有较高的发电效率.

| Abstract: | This paper proposes a new plant for connecting PV system.There are three different concepts of the grid connected PV system：PV modules,string inverter system and central control system.Based on maximum efficiency,the design of PV modules is string architecture.The multiple inverters control strategic is chain method.In different situations,this method avoids the generation of circle current in system.The results show that the method is effective,and this system has excellent capability of high efficiency. |
