摘　　要：本文在空间矢量的基础上,提出了一种计算和分离负载电流中的有功、无功、谐波电流的新方法以及由此构成的检测电路。经过计算机仿真及在有源滤波装置上试验,得到了令人十分满意的结果。A simple new method to measure quickly the active、veactive and distorted cur- rents in three phase systems is proposed. The method is based on the space vector formula- tion, which uses the instantaneous values of voltages and currents in a three-phase system. The scheme is verified experimentally and examed by computer simulation. The results show better measurement characteristics.
