In this paper, the coreless medium-frequency induction melting furnace (IMF) system is 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 harmonics and interharmonics in the supply line currents obtained from field measurements and the raw data have been used in the developed models. It has been shown that the sinusoidal coding method can be used to satisfactorily represent the operation of the IMF system as seen from the supply terminals, with a minimum data storage requirement, and can be used to construct efficient IMF databases for power quality studies. The power quality problems of the IMF system, particularly the problematic time-varying interharmonic voltage distortion, and the interaction of those time-varying interharmonic currents with the passive shunt filter installations connected to the same bus have been investigated in detail, using the developed models.

Field-Data-Based Modeling of Medium Frequency Induction Melting Furnaces for Power Quality Studies
Yilmaz, Ilker; Salor, Ozgul; Ermiş, Muammer (2011-10-13)

Design and implementation of a hybrid system for the mitigation of PQ problems of medium frequency induction steel melting furnaces
Yılmaz, İlker; Durna, Emre; Ermiş, Muammer (2015-10-18)
This paper describes a hybrid system for the mitigation of Power Quality (PQ) problems of medium-frequency coreless induction steel melting furnaces. The hybrid system is composed of passive shunt detuned filters and a Hybrid Active Power Filter (HAPF). Since the single-phase load-resonant thyristor inverter of the work coil operates at variable frequency and supplied from a multi-pulse thyristor rectifier, interharmonic current components, due to cross-modulation phenomenon across ac-dc-ac link, appear in ...

Data Mining Framework for Power Quality Event Characterization of Iron and Steel Plants
Guder, Mennan; Salor, Ozgul; ÇADIRCI, IŞIK; Ozkan, Baris; Altintas, Erinc (2015-07-01)
In this paper, a power quality (PQ) knowledge discovery and modeling framework has been developed for both temporal and spatial PQ event data collected from transformer substations supplying iron and steel (I&S) plants. PQ event characteristics of various I&S plants have been obtained based on clustering and rule discovery techniques. The data are collected by the PQ analyzers, which detect the voltage sags, swells, and interruptions according to the IEC Standard 61000-4-30. The constructed clustering strat...
Numerical analysis of an organic Rankine cycle under steady and variable heat input
Bamgbopa, Musbaudeen O.; Uzgoren, Eray (Elsevier BV, 2013-07-01)
This paper develops a strategy to maintain steady operation of an organic Rankine cycle (ORC) by adjusting evaporator flow rates in relation to the available thermal energy. ORC unit under investigation uses R245fa as the working fluid, for which a regression based approach was implemented to evaluate its state properties. Steady and transient models for unit's subcomponents (pump, evaporator, expander and condenser) were developed. Heat source is considered as solar heated water between 80 degrees C and 95...
