Résumé

In modern steel industry, Electric Arc Furnaces (EAFs) are widely used for iron and scarp melting. The operation of electric arc furnace causes many power quality problems. They generate current harmonics including low frequency and cause of flicker. It is important to build a practical model to describe the behaviour of electric arc furnace. This paper presents a DC Electric Arc Furnace , the model is based on utilization of twelve power rectifiers for the study of harmonics in electrical networks. The model has been implemented using a numerical simulation environment to facilitate later analysis. In the second part of this work we made a reduction of these harmonics, using conventional methods such as the compensation and passive filtering. Several simulations were performed to find the best combination that gives us a minimum THD below the standard "Standard IEEE Std-519."
