This paper presents the modelling and simulation of Centurion electric power system using MATLAB/SIMULINK package. The system considered forms a small part of Tshwane Municipality Network in South Africa. As a suggested solution to increase stability margins of the system, power system stabilizer (PSS) and a flexible ac transmission system (FACTS)-based controllers are installed in the network. The single machine infinite bus 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. PSS and FACTS-based controllers are modelled and tested to validate the effectiveness under various disturbance conditions.
