Abstract :
With the progress of industry, power electronic equipments have been widely used in power systems, but the nonlinear characteristics of these equipment have produced serious harmonic/interharmonic pollution. They can result in the malfunction of remote control systems, light flicker, and communication interference. This makes harmonic/interharmonic analysis an important topic in power quality. In this paper, we propose a two-stage combined method for harmonic/interharmonic analysis. In the first stage, this method is able to do integer harmonic analysis accurately. Then, in the second stage, we remove integer harmonics to do interharmonic analysis. Matlab simulation and field test results are provided to verify its feasibility.
