A strategy of the power-electronics-based emulation of the electric arc furnace (EAF) in the laboratory has been developed. The generalized predictive power control strategy is used in the emulation. The EAF emulation is capable faithfully emulate the operation of the EAF using measured data from a real EAF operation. Thus, the developed strategy enables the real-time emulation of the EAF with its under-scaled control components in various modes of operation in laboratory conditions. As an example, a small-scale active power filter (APF) and static var compensator (SVC) used for flicker mitigation were included as parts of the laboratory system. Selected results of simulation and experimental tests in the laboratory using the data collected from the real 60 t EAF are presented and discussed.
