Stable operation of the power system is one of the key
factors for reliable and quality power supply. Major disruptions in the system operation mode (short circuits, outages of large generating units, transmission lines, etc.) cause significant changes in the parameters of state of the electricity system. The response of the system in such cases is an emergence of electromechanical oscillations in synchronous generators reflected in the fluctuation of the regime parameters (rotational speed, active and reactive power, voltage, power output, etc.). Oscillations can reach an amount that can compromise the stable operation of the synchronous generator and the power system in general. One way to suppress oscillations is to use a stabilizer of the power system as an integral part of the excitation systems of generators. The task of the power oscillation stabilizer is to produce a torque damping component of the electromagnetic torque through the excitation systems. This paper presents the theoretical basics of contemporary power system stabilizers, and on concrete example analyzes its impact on transient stability in a case of a close shortcircuit near TPP Bitola
