摘　　要：DSTATCOM的补偿性能很大程度上取决于指令电流检测方法的检测精度和速度。本文在分析基于瞬时无功功率理论的ip-iq检测法的基础上,研究基于瞬时无功功率理论的无锁相环检测法,有效解决了―检测法在三相不平衡情况下对指令电流检测的缺陷,为实现DSTATCOM的综合补偿提供了有效的检测方法,对指令电流有较好的检测精度和速度。The compensati on perform a nee of DSTATCOM is determi ned in the very great degree by accuracy and speed of the command current detection.In the analysis of p-q,ip-iqcurrent detection methods based on the instantaneous reactive power theory,one non-PLL detection method based on the instantaneous reactive power theory is proposed.This method can rapidly and accurately detect the load side harmonic and reactive component in the power imbalance,effectively solving the defect of ip-iq.
