Abstract
The paper presents a harmonic detection method based on wavelet transform and FFT for electric arc furnaces system. The method not only overcomes the drawbacks of conventional Fourier transform, analyzing transient, non-stationary or time-varying event invalidated, but also avoids the disadvantages that only use wavelet transform can not obtain the precise value at a particular harmonic frequency. Simulation results of MATLAB have proved that the given method is reasonable valid.
