Abstract 

The paper presents investigation results concerning the accuracy analysis of calculating the defined stability factors of the Polish Power System on the basis of power system state matrix eigenvalues associated with electromechanical phenomena. The eigenvalues were calculated by analysis of the disturbance waveforms of the instantaneous power when taking into account introduction of a disturbance to different units. There were analysed the power swing waveforms occurring after introducing the disturbance in the form of a rectangular impulse of different height to the voltage regulation system of generators in generating units of different powers.
