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 particularly advantageous for power quality (PQ) analysis and development of flexible alternating current transmission system 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/Power Systems Computer-Aided Design 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 Field-Data Based EAF Model for Power Quality Studies Goel, Murat; Salor, Oezguel; Alboyaci, Bora; Mutluer, Bilge; Cadirci, Isik; Ermiş, Muammer (2008-10-09) 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.

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 new field-data based eaf model applied to power quality studies Göl, Murat; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2009) Electric Arc Furnace (EAF) modeling has been a common research area to date. This thesis work proposes a new field-data based EAF-specific model. The data used in developing the proposed model is obtained from field measurements of instantaneous voltages and currents of EAF the plants. This model presents the dynamic behavior of the EAF system including all its parts, which are the EAF transformer, the secondary circuit, the electrodes moving and the arc itself. It consists of a cascade connected variable-r...
Online Characterization of Interharmonics and Harmonics of AC Electric Arc Furnaces by Multiple Synchronous Reference Frame Analysis Uz-Logoglu, Eda; Salor, Ozgul; Ermiş, Muammer (2016-05-01) In this paper, a multiple synchronous reference frame (MSRF) analysis framework is developed to determine the positive-and negative-sequence components of all interharmonic and harmonic currents produced by alternating current electric arc furnace (AC EAF) installations, which can be considered as balanced but asymmetrical three-phase, three-wire loads on the power system. The aim of developing the MSRF analysis framework is twofold; deep understanding of the EAF characteristics, and fast and accurate gener...
