Abstract:
Flexible AC Transmission Systems (FACTS) devices can be operating in shunt or series or compound with the power system to compensate the reactive power. By controlling the thyristor valves, it can control on the voltage system and the reactive power to improve the power system quality. The purpose of this paper is to study the effects of varies controllers: SVC and STATCOM. A comparison of the effectiveness of installing reactive power compensators was presented in large-scale power networks. A suitable bus was first identified using modal analysis method. The single Static Var Compensation (SVC) and single Static Synchronous Compensation (STATCOM) were installed separately on the most critical bus. The effects of the installation of different devices on power loss reduction, voltage profile improvement, and voltage stability margin enhancement. This paper discusses the SVC and STATCOM modules for operation and control to compensate the reactive power to enhance the power system quality. Also, this paper shows the using of MATLAB/Simulink software to describe the operation and control steps for the SVC and STATCOM
