  One of the important issues in electric arc furnace (EAF) of the steel industries is the effective compensation of the EAF. In this paper, firstly an optimal design model for the EAF is presented. Then, a thyristor controlled reactor (TCR) is installed in parallel with the TCR. The parameters of the TCR are designed optimally to compensate the reactive power of the EAF. In the proposed method, a hyperbolic-exponential model is considered for the EAF and also a sinusoidal voltage flicker with the frequency in the range human vision (between 4-14 Hz) is included. In addition, the presence of the harmonic filters with the TCR is discussed. The results of the simulation show that the TCR can compensate the effects sinusoidal voltage flicker. Moreover, the results indicate that compared to the other methods, the average time response is about the half period of a cycle. Manuscript profile
