Résumé

DC electric arc furnace is an important nonlinear time-varying load in power system. Due to the adverse effects produced by the operation of arc furnace, 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 the stochastic nature of the electric arc current-voltage characteristic. Our model is consisting of four different structures basing 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. Finally, the simulation results are compared with different structures of a DC EAF, when the Total Harmonic Distortion (THD) is determined and spectral representation to compares each structure is better in order.
