The nonlinear and time varying nature of Electric Arc Furnace (EAF) causes power quality problems such as harmonics, flicker and voltage /current imbalances. In order to analyze the power quality of power system containing EAF, mathematical model of arc furnace becomes useful and informative. This paper presents different models of alternating current operated arc furnace to analyze the power quality in electric power system. The behavior of these models under static and dynamic conditions is studied. A comparison is also made between these models of arc furnace. Simulation results in MATLAB/ SIMULINK shows the voltage/current wave forms and percentage harmonic component in arc furnace system.
