Simulation of electric arc furnace characteristics for voltage flicker study using MATLAB

Power quality is becoming a more concern of today's power system engineer due to the rapid growth of non-linear loads, such as power electronic control equipments and electric arc furnace (EAF). Harmonics and voltage flicker are the power quality problems which are introduced to the power system as result of non-linear behavior of the electric arc furnace operation. Electric arc furnace model is needed to analyze the power quality. There are numbers of arc furnace models. This paper presents a time domain model called exponential-hyperbolic for electric arc furnace using MATLAB. The model is used to study its behavior on the power system using MATLAB. To analyze the method, several characteristics for different operating conditions are investigated.
