This is the second of a two-paper series, in which the field-data-based analytical method proposed in Part I has been extended to determine the amount of harmonic currents absorbed by the shunt harmonic filters of the iron and steel (I&S) plants from the rest of the system. The nonlinear characteristics of the plants and the utility are modeled as harmonic current sources, whereas the linear parts of the proposed extended model consist of passive circuit elements, with the harmonic filter RLC circuit parameters also integrated into the model. This extended method, which can be also used for harmonic contribution assessments, requires sample-by-sample time-synchronized harmonic current measurements inside the plants and at the point of common coupling (PCC). It eliminates the need for harmonic voltage measurements at the expense of the need for inside-plant measurements. It has been verified both by computer simulations and by application on field data. The results have shown that the proposed method is a successful tool to determine the magnitude of harmonic currents that are absorbed by the harmonic filters of I&S plants connected to the PCC, particularly when measured harmonic currents of I&S plants exceed the actual contributions.

Identification of Harmonic Current Contributions of Iron and Steel Plants Based on Time-Synchronized Field Measurements - Part II: Inside Plants Unsar, O.; Salor, O.; ÇADIRCI, IŞIK; Ermiş, Muammer (2013-10-11) This is the second of a two-paper series, in which the field-data-based analytical method proposed in Part-I has been extended to determine the amount of harmonic currents sunk by the shunt harmonic filters of the Iron and Steel (I&S) Plants from the rest of the system. The non-linear characteristics of the plants and the utility are modeled as harmonic current sources, whereas the linear parts of the proposed extended model consist of passive circuit elements, with the harmonic filter RLC circuit parameter...
Identification of Harmonic Current Contributions of Iron and Steel Plants Based on Time-Synchronized Field Measurements-Part I: At PCC Unsar, Ozgur; Salor, Ozgul; ÇADIRCI, IŞIK; Ermiş, Muammer (2014-11-01) This is the first of a two-paper series, in which a field-data-based analytical method is proposed to determine the harmonic current contributions of each iron and steel (I&S) plant supplied from the point of common coupling (PCC) and the upstream loads at the utility side. The nonlinear characteristics of the plants and the utility are modeled as harmonic current sources, whereas the linear parts of the proposed model consist of passive circuit elements.

Determination of Harmonic Current Contributions of Plants Supplied from PCC Based on State Estimation Sezgin, Erhart; Göl, Murat; Salor, Ozgul (2015-05-19) In this paper, a state estimation based method is proposed to determine harmonic current contributions of plants supplied from a Point of Common Coupling (PCC). By using Weighted Least Squares (WLS) state estimation, it is aimed to improve harmonic voltage measurements acquired from conventional voltage transformers, which are employed commonly in the power systems. Using measured harmonic currents and estimated harmonic voltages, harmonic contributions of all plants have been determined by employing the No...
Calculation of the Raman Linewidths of Lattice Modes Close to the alpha-beta Transition in Quartz Lider, Mustafa Cem; Yurtseven, Hasan Hamit (Walter de Gruyter GmbH, 2012-12-01) The Raman frequencies of the lattice modes (147 cm(-1) and 207 cm(-1)) are analyzed for the alpha-beta transition in quartz according to a power-law formula with the critical exponent by using the experimental data. The temperature dependence of the Raman frequency is associated with the order parameter (polarization P) for this transition in the quartz crystal.
