Simulation Study of Static Var Compensator (SVC) Using MATLAB/Simulink

This research presents a MATLAB/Simulink-based simulation study of Static Var Compensator (SVC) systems, focusing on comparative analysis of voltage performance in power systems with and without SVC installation. The simulation framework implements thyristor-controlled reactor (TCR) and thyristor-switched capacitor (TSC) configurations using Simulink's Power Systems library blocks. Through comprehensive simulation experiments, we analyze the impact of SVC implementation on grid stability and voltage regulation under various load conditions, including sudden load changes and fault scenarios. Key control algorithms modeled include voltage-reactive power characteristics and PID-based voltage regulation. The study examines voltage fluctuations in systems without SVC compensation and provides quantitative comparisons with SVC-enhanced systems using performance metrics like voltage deviation and recovery time. This investigation aims to deepen understanding of SVC's role in power system optimization, providing valuable references for reactive power compensation design and stability enhancement strategies. The simulation models incorporate practical implementation aspects such as firing angle control for TCR and switching logic for TSC components.
