| Abstract: | 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. |
