摘　　要：通过对虚拟三相电机中合成磁势的理论推导 ,给出一种基于合成综合矢量特性实现的电网谐波检测新方法 .该方法可以解决非正弦三相不平衡系统中电压和电流谐波分量的检测问题 .理论推导与计算机仿真结果证明了新方法的有效性与正确性 .By the theoretical analysis of the composed magnetic motive force (m.m.f) in the dummy three_phase electric motor, this paper presents a novel harmonic detection of power system based on the characteristic of the composed fan_in vector, which can detect the voltage and current harmonics of nonsinusoidal and unbalanced three_phase power system. The feasibility and the validity of this method are verified by theoretical analyses and computer simulation.
