Parameters influence in electric arc modeling

Abstract

The aim of this research is to study parameters influence in the electric arc modeling. In order to perform this, a study of the electric arc behavior was made by implementing three models of the electric arc in the Matlab/Simulink environment. Furthermore, graphical user interfaces in Matlab were developed, the purpose being to obtain the dynamic voltage-current characteristic of the electric arc. Both, simulated and measured data were compared and presented in this research. From an AC electric arc furnace, having the capacities of 100 tones, fed by medium voltage, the measured data were acquired using the data acquisition board, ADA3100.
