Analysis of Non-Stationary Signals in Power Systems using Wigner Transform and Min-Norm Method

Leonowicz, Z (Wroclaw University of Technology, Poland)

2008-01-30

Abstract: Time-varying spectra of non-stationary time-series commonly used are spectrograms from the Short-Time Fourier Transform (STFT). The most prominent limitation of the Fourier Transform is that of frequency resolution. To overcome the limitations the Wigner-Ville Distribution and the Min-Norm subspace method have been applied for spectrum estimation of non-stationary signals caused by switching on capacitor banks and by a short circuit at the output of a frequency converter. Investigation results confirm the advantages of the advanced methods.
