Analysis of Reactive Power Compensation During Fault Conditions in Power System Using Simulink Model of SVC FACTS Device

Abstract

Flexible alternating current transmission system (FACTS) devices are capable of controlling the active and reactive power flows in a transmission line by controlling its series and shunt parameters. This work presents a review of comparison of different FACTS controllers in the power system for stability enhancement. The focus of this research is simulation of single-phase TCR (thyristor-controlled reactor)/TSC (thyristor switch capacitor) static VAR compensator (SVC) in MATLAB/SIMULINK to solve voltage regulation and system dynamic performance deficiencies. To support transmission voltage immediately after major disturbances, a thyristor-based controller SVC can be used to provide rapid voltage control. To maintain voltage profile in the transmission system, an SVC is used since many years, which proved itself a highly effective device.
