Résumé

In modern steel industry, Electric Arc Furnaces are widely used for iron and
scarp melting. The operation of electric arc furnace causes many power
quality problems such as harmonics, unbalanced voltage and flicker. The
factors that affect Electric arc furnace operation are the melting or refining
materials, melting stage, electrodes position (arc length), electrode arm
control and short circuit power of the feeder, so, arc voltages, current and
power are defined as a nonlinear function of arc length. This study focuses on
investigation of unbalanced voltage due to Electrics Arc Furnace operation
mode. The simulation results show the major problem of unbalanced voltage
affecting secondary of furnace transformer is caused by the different
continues movement of electrodes.
