TBSC Compensator for Reactive Power Compensation along with Transient Free Switching of Capacitor Bank

A method for compensation of reactive power along with transient free switching of capacitor bank is presented in this paper. The system based on Thyristor Binary Switched Capacitor (TBSC) banks which are nothing but the set of Thyristor Switched Capacitor (TSC) banks for compensation. These are placed in binary sequence to give approximate continuous compensation of reactive power. The switching of TBSC bank is transient free which is to be carried out in closed loop system. The objective of this paper is to provide a minimum cost topology for compensation of reactive power at load end by the Thyristor Binary Switched Capacitor (TBSC) bank. In this paper, simulation results of this method are presented. The step less reactive power compensation is achieved and due to filtering action of TBSC the harmonic content at source side is reduced.
