Emulation of Electrical Arc Furnace in Laboratory Conditions using Measured Data from Real Furnace Operation

A novel strategy of the power-electronics-based emulation of the Electrical Arc Furnace (EAF) has been developed. The EAF model consists of a voltage source power electronic converter controlled by Generalized Predictive Power Control (GPPC) strategy with long predictive horizon. The converter consumes the active and reactive powers corresponding to the data collected from the real EAF operation. A small-scale Static Var Compensator (SVC) for compensation of EAF’s adverse effects connected to a grid simulator is a part of the whole laboratory system. A comparison of the behavior of the real EAF and its emulated counterpart in terms of the frequencies responsible for flickering is provided. Selected results of experimental tests in the laboratory that use the data collected from the rea160 t EAF are presented and discussed.
