Harmonics Analysis of Thyristor controlled Reactor circuits

T.Vijayakumar and A.Nirmalkumar

Abstract—Harmonics that arise from the interaction of thyristor controlled reactors (TCRs) and power systems are difficult to analyze. Two methods are described. The first develops a Fourier matrix model for the TCR. The coupling between the harmonics through the system impedance is clearly shown. The second method uses state variable analysis to write the system equations for a circuit containing a TCR. The systems of equations that result are linear with time varying coefficients. Using linear system theory statements and resonance can be made. Simulation of FC-TCR was done and FFT analysis is performed using matlab .The spectrum for the current is presented.

Index Terms—Static VAR Compensators, Harmonics, Harmonic Analysis.
