An EMTP study of flicker generation and transmission in power systems due to the operation of an AC electric arc furnace

Many contributions have been presented to the international technical community dealing with flicker generation due to AC electric arc furnaces (EAF). This paper presents the results of measurements carried out in the AC arc furnace feeding system, inside and outside the factory. Because the steel making factory under consideration is fed with two different lines from the same electrical grid, it ia possible to analyse the transmission of the perturbation across the net taking simultaneous flicker measurements in the system. A PSCAD simulation of the real situation using a model of the UIE 868 flickermeter developed to study this kind of problem is also presented
