Abstract

This paper presents the application of signal processing tools for power quality analysis. Three signal processing techniques are considered: the discrete Fourier transforms, the wavelet filters and the discrete short-time Fourier transforms. It is designed an adjustable speed drive with a six-pulse converter using EMTP/ATP and it is presented normal energizing of utility capacitors. Finally, each kind of electrical disturbance is analyzed with example representing each tool. A qualitative comparison of results shows the advantages and drawbacks of each signal processing technique applied to power quality analysis
