Abstract :

A complex assemblage of equipment and circuits for generating, transmitting, transforming, and distributing electrical energy constitutes an electric power system. Power system stability has been recognized as an important problem for secure system operation. Different types of stabilities have been discussed in this paper; especially small signal stability is explained in detail. The power system stabilizer (PSS) increases stability limits by modulating generator excitation to provide damping to the oscillations of synchronous machine rotors (0.2-2.5 Hz). Thus PSS is used to improve the small signal stability. In this paper, a test power system is considered and PSS is implemented on the excitation system of synchronous machine. The simulations are performed in Matlab/Simulink environment. The results show that PSS appreciably reduces the damping time of oscillations.
