power_svc_1tcr3tsc Demonstration File

This article introduces the power_svc_1tcr3tsc demonstration file in MATLAB, which primarily serves for static var compensator (SVC) control analysis in power system simulations. SVC (Static Var Compensator) is a widely used reactive power compensation device in electrical power systems that enhances grid voltage stability. TCR (Thyristor Controlled Reactor) and TSC (Thyristor Switched Capacitor) are two core components of SVC, regulating system reactive power through thyristor-controlled reactors and switched capacitors respectively.

The MATLAB demonstration file illustrates the coordinated operation of TCR and TSC, typically including the following analysis components: Dynamic Response: Simulates SVC regulation effects during grid voltage fluctuations, observing TCR and TSC firing angle control strategies implemented through programmable logic blocks. Harmonic Analysis: TCR generates harmonics under non-full conduction states, where the demonstration may include FFT-based spectrum analysis modules to evaluate harmonic distortion. Parameter Impact: Investigates compensation effectiveness by adjusting reactor/capacitor ratings or control delays through variable parameter tuning in Simulink blocks.

For researchers in power electronics or grid stability fields, this example provides valuable insights into SVC modeling methodologies and control logic implementation. Users can directly execute the demonstration through MATLAB's Simulink environment and modify parameters via script-based configuration or GUI interfaces to adapt to different application scenarios.
