Abstract

This paper studies improving the power factor by using Thyristor Controlled Reactor (TCR) shunted with a fixed capacitor to get a controlled source of reactive power. This technique has three topologies of TCR connection like Star, Delta, and Hybrid. The fuzzy controller is used to control the thyristor firing angle according to the reactive power measured at the PCC to improve the power factor. Also, the paper discusses the using of the hybrid technique to solve the problem of Total Harmonic Distortion (THD) as one side effect of the using the TCR system.
