Résumé

bstract: It is very well known that electric arc furnace (EAF) as a three-phase charge one of the most important generators of harmonic currents, reactive power and unbalanced conditions in electrical power systems. To study the effect of the harmonics, it is necessary to know the values of the electrical parameters of the arc furnace electrical installation as well as how the arc can be modelled. Our electric arc furnace model is implemented using a numerical simulation environment. In this paper we treats the harmonic that generated by the DC EAF in all positions of the three electrodes, that is to say when the electrode in high position and in low position "flooded in the liquid", and in every stage we determines the THD and the proportion of the harmonic most major. Finally this study shows the best working of a DC EAF that offers e the minimum of the THD and harmonic and it contributes in the increase of the length of the life of the transformer and the cables.
