Comparison of magnetically controlled reactor (MCR) and thyristor controlled reactor (TCR) from harmonics point of view

Shunt reactors are used to compensate for the effects of line capacitance, particularly to limit voltage rise on open circuit or small load.Magnetically controlled reactor (MCR) is a device in which DC pulsing through a special winding controls inductive susceptance. MCR has a high saturation of the magnetic circuit with optimal magnetic and electrical circuit parameters that ensures less than 2–3% main harmonic distortion even without special filters operation.In this paper, comparison of MCR and TCR from the point of view of harmonics, is studied. A detailed model of reactor is used to illustrate the ideas presented throughout the paper.
