Abstract
This paper presents a digital signal processing laboratory developed for analysis of voltage events in power systems. The designed laboratory permits the analysis of simulated voltage events of different magnitude, duration and point-on-the-wave of beginning as well as the analysis of real voltage events from records taken by power quality monitoring equipment, using different signal processing tools such as r.m.s magnitude, Fourier analysis, Kalman filtering and wavelet analysis. This laboratory has been used as a benchmark in the development of new signal processing methods for the complete characterization of voltage events in power systems as well as a powerful teaching tool in electrical power quality courses.
