Abstract
This article presents some results of studies on the influence of digital signal filtering at the analysis results of lowfrequency electromechanical oscillations in interconnected power systems. Selected and prepared methods of signal analysis are used to analyse in real-time the signals measured by phasor measurement units . It is shown that preliminary digital filtering of signals improves the reliability of mentioned analysis results. References 11, tables 2, figure 1.
