Harmonics Reduction of Thyristor Controlled Reactor with Minimal No Load Operating Losses
By Abdulkareem Mokif Obais, Dr. Jagadeesh Pasupuleti

Abstract —
In this paper a new approach of thyristor controlled reactor (TCR) harmonics treatment is presented. The design methodology of this approach is based on suppressing the TCR harmonic current components by inserting a series LC circuit between the ac source and the parallel combination of TCR and filtering circuit. The series LC circuit is tuned at the ac supply fundamental frequency, whereas the filtering circuit is built of a set of significant odd harmonic filters characterized by minimal no load operating losses and no reactive power contribution at the fundamental frequency. The proposed filtering circuit is less sensitive to the adjacent harmonics generating circuits in the power system network, therefore it remains always efficient. A demonstrating system is designed and tested on the computer program PSpice. In this system, the TCR odd harmonics are reduced to one-third the values accepted by IEEE 519-1992.1

Key Words — TCR, Harmonics, static Var, controlled reactor, reactive power absorption.
