摘要(Abstract)：

对于配电网静止同步补偿器(distribution static synchronous compensator,DSTATCOM),并网电压的相位实时检测是无功功率检测以及各种坐标变换的关键。在传统的基于同步旋转坐标系的锁相环的基础上,提出了基于级联延时信号消除(cascaded delayed signal cancellation,CDSC)的锁相环算法,以抑制电网电压负序分量和谐波分量对检测结果的影响,并采用拉格朗日插值算法提高相位检测的精度和速度。将该方法应用于负载平衡和不平衡情况下的星形连接的级联式DSTATCOM系统中,平衡情况下采用基于分相控制和有功电压矢量叠加法的控制策略,不平衡情况下采用基于分相控制和零序电压注入法的控制策略,仿真结果验证了控制方法的正确性和有效性。
