Title
(ZH) 用于并网过渡的功率逆变器控制
Abstract
(ZH)

公开了一种用于功率逆变器(140)的控制系统。所述功率逆变器被耦合到接触器(180),所述接触器(180)被配置为连接电网(190)和去连接电网(190)。所述控制系统包括多个输出电压传感器(172-175)和多个输出电流传感器(182-185)。一旦连接所述电网,所述输出电压传感器被配置为测量在所述接触器处的至少两个线路电压,所述输出电流传感器被配置为测量在所述接触器处的至少两个线路电流。所述控制系统还包括控制器(200),其被连接到所述输出电压传感器和输出电流传感器。所述控制器被配置为确定用于所述功率逆变器的输出电压的目标幅值和目标频率。所述控制器还被配置为基于所述目标幅值和所述目标频率确定多个功率晶体管切换脉冲。所述控制系统还包括接口电路(210),其被连接到所述控制器和所述功率逆变器。所述接口电路被配置为向所述功率逆变器提供所述功率晶体管切换脉冲。
