STATCOM Implementation Using DC Voltage Controlled Modulation Technique

This documentation presents a MATLAB simulation of a STATCOM (Static Synchronous Compensator) utilizing DC Voltage Controlled Modulation Technique. The STATCOM serves as a crucial power system device for reactive power compensation and voltage regulation. Through the DC Voltage Controlled Modulation Technique implementation, the STATCOM effectively manages power flow control and maintains optimal voltage levels within the system. The simulation incorporates key MATLAB functions for power electronics control, including PWM (Pulse Width Modulation) generation and DC link voltage regulation algorithms. The core implementation involves: - Voltage source converter (VSC) modeling with IGBT-based inverters - DC link capacitor voltage control using PI regulators - Phase-locked loop (PLL) synchronization with grid frequency - Reactive power calculation and reference generation modules This simulation demonstrates the STATCOM's performance in stabilizing power systems through dynamic reactive power injection/absorption, showcasing transient response characteristics and steady-state voltage regulation capabilities. The model includes comprehensive system monitoring features for analyzing voltage profiles, power factor correction, and harmonic distortion levels under various load conditions.
