Abstract
A strategy of 'group-harmonic' identification is proposed for re-evalu ating harmonic levels in power systems. The proposed strategy can reli eve the problem of spectral leakage in the conventional application of the fast Fourier transform (FFT). Incorporating group-harmonic identi fication, the FFT algorithm can retain its efficiency for accurate har monic calculations, especially for power systems with nonstationary wa veforms.
