Abstract
In this study, the traditional thyristor controlled reactor is conditioned to be an almost harmonic-free inductive static Var compensator. The proposed configuration is constructed of a traditional TCR shunted by a parallel resonance circuit and the parallel combination is connected in series to a series resonance circuit. The parallel and series resonance circuits are tuned at the power system fundamental frequency. The series resonance circuit offers almost short circuit to the AC source current fundamental, while it offers very high impedance to the harmonic current components released by the TCR. The parallel resonance circuit offers very high impedance to the AC source current fundamental, while it offers almost short circuits to the harmonic current components released by the TCR. The two circuits operate coherently such that negligible current harmonics are permitted to flow in the AC source side. This type of harmonic treatment is not sensitive to other harmonic sources in the power system network, where this compensator is installed. The no load operating losses of this compensator are negligible compared to its reactive power rating. The proposed compensator is designed and tested on PSpice.
