Study on Harmonic Detection Method Based on FFT and Wavelet Transform
Aiming at the problem of difficult to detect the dynamic harmonic quickly and accurately using the current existence of harmonic detection methods in power system,making full use of the advantages of FFT detecting steady-state harmonic and wavelet transform detecting dynamic harmonic, introduced a method that combines the FFT with the wavelet transform. Finally, used the tool of MATLAB to simulate,the simulation results show that this method can not only detect the steady-state harmonic component and transient waveform component accurately,but also detect the signal abrupt point.
