Flicker Study Using a Novel ARC Furnace Model

Voltage flicker and harmonics are the types of power quality problems that are introduced to the power system as a result of arc fumace operation. Utilities are concemed about these effects and try to take precautions to minimize them. Therefore, an accurate model of an arc fumace is needed in order to test and verify proposed solutions to this end. In this paper, an arc fumace model is developed and implemented in Simulink environment by using both chaotic and deterministic elements. Moreover, modeling and simulation of IEC flickermeter are also performed to evaluate the severity of fluctuations in the simulated arc furnace voltage.
