Abstract
This project investigates the application of static VAR compensator (SVC) to improve power system stability. A static VAR compensator is a set of electrical devices that can be used to provide fast acting reactive power on high-voltage electricity transmission networks. SVCs can be used to regulate voltage, power factor, harmonics, and stabilize the system. Unlike a synchronous condenser which is a rotating electrical machine, a static VAR compensator has no significant moving parts (other than the internal switch gear). There are two types of SVCs: Thyristor Controlled Reactor (TCR) and Thyristor Switched Capacitor (TSC). Both types are discussed in this report, where the application of SVC in single and multi-machine system is carried out and discussed in details. Simulink is used to study the characteristics of SVC and its impact on power system stability. Results show the effectiveness of SVCs in maintaining power system stability.
