Modeling and simulation of Umlazi suburb of Durban municipality network (South Africa)

The main focus is to model and simulate the portion located in the ULMAZI suburb of the Durban municipality network incorporating FACTS devices, in order to improve the stability of the whole network. Instead of doing modeling and simulation for each generator while they all have the same characteristics, a simplified dynamic model of a power system is used in this study, named Single Machine Infinite Bus (SMIB) power system. This model consists of a single synchronous generator connected through a parallel transmission line to a very large network which is UMLAZI approximated by an infinite bus. For the design purpose, the model of example power system which is a SMIB power system installed with the TCSC device and SSSC connected in series is developed in MATLAB/Simulink. Simulation results in terms of power system responses prove the enhancement of power system performance and fast damping of power system oscillation.
