Design and implementation of a laboratory scale three-phase thyristor controlled reactor

Abstract

This paper presents design, implementation and analysis of a laboratory scale three-phase thyristor controlled reactor (TCR). The performance of the TCR is demonstrated through many case studies for different connections of the TCR branches. A detailed harmonic analysis is carried out to understand the harmonic behaviour of the setup. The fundamental reactance characteristics of the TCR is also obtained experimentally and compared with ideal characteristics. A simulation model is developed using 'MATLAB' to verify the oscilloscope captured-waveforms. This setup is found to be a good learning resource for introducing variable reactance nature of a TCR. © 2017 IEEE.
