A new three phase time-domain model for electric arc furnaces using MATLAB

Abstract

This paper presents a new time domain model for electric arc furnaces using MATLAB. The model can simulate both nonlinear and time varying nature of such loads, which create flicker, harmonics, and voltage/current unbalance. In this model, Cassie and Mayr equations are used in three-phase mode and the effects of arc furnace transformer tap changer and flexible cables mutual inductances are considered. The proposed model takes into account the system inter-relation of parameters and arcing conditions as well.
