Aiming at the problems of thyristor switched capacitor in three-phase power supply system, the working principle and switching process of TSC are analyzed. The triangular external methods of capacitors are modeled, dynamically simulated and reaearched by using Matlab/Simulink. The control plans of the reasonable switching ways and time of reactive power compensation capacitor are proposed, and the impluse current in the switching process is effectively reduced.
