A new electric arc furnace (EAF)-specific model based on field measurements of instantaneous furnace voltages and currents has been proposed. This model presents the dynamic behavior of the EAF system including all parts, i.e. the EAF transformer, the secondary circuit, the electrode movements and the arc. It consists of a cascade connected variable-resistance and -inductance combination to represent the time variation at the fundamental frequency, and a current source in parallel with it to inject the harmonics and interharmonics of the EAF current. The model takes into account several typical tap-to-tap periods of the specific EAF operation. This model is especially advantageous for power quality (PQ) analysis, and development of FACTS solutions for PQ problem mitigation of a given busbar supplying single- or multi-EAF installations. The validity of the proposed model has been verified by comparing EMTDC/PSCAD simulations of the model with the field measurements. The results obtained have shown quite satisfactory correlation between the proposed model and the actual EAF operation.

A New Flicker Contribution Tracing Method Based on Individual Reactive Current Components of Multiple EAFs at PCC Altintas, Erinc; Salor, Oezguel; ÇADIRCI, IŞIK; Ermiş, Muammer (2009-10-08) In this paper, a new flicker contribution tracing method has been proposed to determine the individual flicker contributions of multiple electric arc furnace (EAF) loads to the flicker measured at the point of common coupling (PCC). The proposed method decouples the flicker contribution of the interconnected electricity system from the individual contributions of the loads connected to the measured PCC, using the individual current variations of the loads, and the estimated short-circuit system impedance. I...
A Kalman Filter Based Approach for Light Flicker Evaluation of Power Systems Kose, Neslihan; Salor, Ozgul; Leblebicioğlu, Mehmet Kemal (2009-01-01) In this paper, a Kalman filtering based approach is proposed to measure the light flicker of the electricity transmission systems. Analytical expressions of the instantaneous light flicker sensation are obtained beginning from a voltage waveform and these expressions are used to obtain a flicker estimation method based on the IEC (International Electrotechnical Commission) flickermeter. In the proposed method, the frequency domain components of the waveform are obtained by Kalman filtering and these compone...
Field-Data-Based Modeling of Medium Frequency Induction Melting Furnaces for Power Quality Studies Yilmaz, Ilker; Salor, Ozgul; Ermiş, Muammer (2011-10-13) In this paper, the coreless, medium frequency induction melting furnace (IMF) system, has been represented by alternative field-data-based models, developed specifically for power quality studies. The IMF operation has been represented by a variable series RL circuit to model the fundamental components of electrical quantities, and a shunt-connected current source, to model the generated harmonics and interharmonics over a typical melting cycle. Both the sinusoidal coding method applied to the major harmoni...
Exponential Smoothing of Multiple Reference Frame Components With GPUs for Real-Time Detection of Time-Varying Harmonics and Interharmonics of EAF Currents Balouji, Ebrahim; Salor, Ozgul; Ermiş, Muammer (2018-11-01) In this research work, a multiple synchronous reference frame (MSRF)-based analysis method, used together with exponential smoothing (ES) to accurately obtain the time-varying harmonics and interharmonics of electric arc furnace (EAF) currents, is proposed. The proposed method has been implemented on NVIDIA Geforce GTX 960 graphics card for the parallel processing of all harmonics and interharmonics so that real-time processing of the EAF currents obtained from a measurement point of the electricity transmi...
