Abstract (Summary)

The primary purpose of a power system is to transform energy from one of its naturally obtainable forms into electricity, and then supply it through grids to points of consumption. With the increasing demand for electricity, more reliable methods are required to keep the quality of power in the desired range. This paper focuses on the impacts that a static var compensator (SVC) has on power quality. A two-area power system was used to demonstrate the power quality enhancements of a SVC, and simulations were done on the Real Time Digital Simulator (RTDS) and Electrical Transients Analyzer Program (ETAP). Simulations were performed for both steady-state and transient conditions to exhibit the dynamic capabilities of a SVC. Also, two different types of SVC controls were used and their effectiveness was analyzed. Simulations showed that the steady-state voltage, namely at bus 8 where the SVC was installed, improved from 0.94pu to 1.0pu. In addition, the voltage recovery time of bus 8 was improved from over 40s to approximately 2s.
