DBF Factors for Fast Estimation of Waveform Distortion in Ship Systems - Case Study

This paper deals with a problem of fast estimation of waveform distortions by means of Fourier transform as well as wavelet transform. The method of fast recognition of frequency band affected by high frequency content has been described. It has been based on the auxiliary waveform distortion band factors DBF. Merits of presented method as well as its limitations have been described on the basis of real voltages registered in ships' electrical power systems. This method has been presented in author's previous papers, e.g. (Tarasiuk, 2004) as a part of a method based on complementary application of Fourier and wavelet transforms. However, this paper has described the new research results and extended analysis focused exclusively on these above mentioned DBF factors.
