Abstract

This paper presents the modelling and simulation of Centurion electric power system using MATLAB/SIMULINK package. The basic system is tested under large and small disturbances to study the dynamic behaviour of the system and the stability margins associated with the different configurations of the system. The single-machine infinite bus (SMIB) power system model is considered, with the synchronous generator being represented by model 1 with both the generator main field winding and the damper winding in q-axis, and developed to evaluate the impact of power system stabilizer (PSS) with automatic voltage regulator (AVR) and flexible ac transmission system (FACTS) based controllers on power system stability. As a suggested solution to increase stability margins of the system, PSS with AVR are installed in the network. FACTS controllers are added, modelled and tested to validate the effectiveness on the different stability margins under both large and small disturbances.
