Abstract:
Topology for closed loop reactive power compensation suitable for dynamic loads using TCR is presented. Firing angle range of TCR is selected in such a way to keep the harmonic content at a minimum level. Simulation results show that the proposed scheme can achieve reactive power compensation in less than a half cycle and the harmonics contents of source are maintained at insignificant levels due to delta connection of TCR and appropriate firing angle range selection of TCR.
