Evaluation of Power Quality in Arc Furnace Using Iec Flicker Meter

Power quality determines the fitness of electrical power to consumer devices. .Voltage flicker and harmonics are the types of power quality problems that are introduced to the power system as a result of arc furnace operation. Utilities are concerned about these effects and try to take precautions to minimize them. Therefore an accurate model of an arc furnace is needed to test .In this paper arc furnace is modeled using both chaotic and deterministic elements. The flicker effect, which is the manifestation of voltage fluctuations, is captured using chaotic circuit, whereas a dynamic model in the form of differential equation is used for the electric arc. The resulting model produces both effects , this effect can be measured by IEC Flickermeter
