Abstract
A strategy of `group-harmonic´ identification is proposed for re-evaluating harmonic levels in power systems. The proposed strategy can relieve the problem of spectral leakage in the conventional application of the fast Fourier transform (FFT). Incorporating group-harmonic identification, the FFT algorithm can retain its efficiency for accurate harmonic calculations, especially for power systems with nonstationary waveforms
