Numerical modeling of some nonlinear processes in electric arc furnace operation

This paper presents a study regarding the experimental validation of a mathematical model used to simulate the electric arc behavior, taking into consideration a technological phase of the electric arc furnace process. In order to do this, the mathematical model of the electric arc was implemented in Simulink software. In this paper were presented results obtained in the meltdown stage of the charging material. This model can be useful from the point of view of power quality analysis and electric arc control. Results obtained by simulation were compared with measured data.
