Electric Arc furnaces (EAF) are intensive distressing, unbalanced, stochastic, time varying, non-linear loads which are used in steel industry. Their non linearity and dynamic characteristics produce harmonic problems and fluctuation of voltage. Advanced control strategy based Custom Power Device such as Unified Power Quality Conditioner (UPQC) is designed to provide significant reduction in voltage flicker on the power system. Moreover, to estimate the severity of fluctuations, IEC flicker meter is simulated. The modeling and simulation of the UPQC has been demonstrated using the electromagnetic transient simulation program PSCAD/EMTDC.
