000000139 520__ $$aContemporary power systems, which contain a considerable number of non-linear loads, require advanced methods of spectral analysis for their investigation and control. Fourier-based spectral methods are useful in stationary signal analysis but is insufficient in the case of numerous real-life problems when signal contents changes in time. Nonstationary signals are usually analysed with STFT (Short-Time Fourier Transform). The method presented in this paper employs recently introduced S-transform which is an important development of STFT.
