MATLAB/Simulink-Based Modeling and Operation of Power System Stabilizer

This paper describes the operating performance of the Power System Stabilizer (PSS) for different power system case studies. The functional blocks of PSS are developed in Simulink and the simulation carried out. The damping oscillation variation of PSS for the various power system conditions (light, nominal and high load and fault) is carried out and the voltage and reactive power variations are illustrated. The PSS system behavior is demonstrated on Single Machine Infinite Bus (SMIB) model and simulation carried out in Simulink-based MATLAB environment
