Power quality improvement of eight bus system using TCTC

Abstract

If the reactive power of the load is changing rapidly, a suitable fast response compensator is needed. SVC and TCTC (Thyristor controlled tap changer) are two such compensators belonging to FACTS devices. A model for the Thyristor tap changer has been designed to improve the voltage level at the load end. Smooth reactive power control is achieved by varying the firing angle of TCTC system. The simulation results of eight bus TCTC system are presented.
