Simulation based reactive power compensation by using TBSC/TBSR for dynamic load

Abstract

The advanced control method for electric reactive power compensation with the help of electronics components is binary current control method. This method allows a sufficient number of compensating branches to establish a fine and precise control of reactive power in electrical system. This method consists of Thyristor binary switched capacitor (TBSC) and Thyristor binary switched reactor (TBSR), which are based on the series of Thyristor switched capacitor (TSC) and Thyristor controlled reactor (TCR). The bank of TSC, TCR arranged in binary form i.e. split bank in multiple of two. For harmonic elimination use transient free switching of TBSC, TBSR In this paper three topologies are explained 1) TBSC 2) TBSR 3) TBSC-TBSR for reactive power compensation of dynamic load. In the third topology excessive KVAR given by TBSC is absorbed by TBSR. The simulation results show that the proposed topologies can achieve reactive power compensation.
