A power system transient state estimation method based on Kalman filtering = Güç Sistemleri için Kalman Süzgecine Dayalı Bir Geçici Durum Kestirim Yöntemi

Mehmet KARADENİZ

On a power network, events are desired to be monitored to discover their reasons and to take preventive actions. Today, phase measurement units are used to obtain transient data of network, however these devices are expensive and it is not considered as a practical option to place one on each node of the network. Therefore, methods of estimating voltages and currents at non-measured points of the network are required. In this study, a special first-order Kalman Filter is introduced and transients on a power network connected by short lines are estimated using only line parameters. Simulation r ...More

Amplitude and phase estimations of power system harmonics using deep learning framework

Özgül SALOR-DURNA

In this study, a new method for the analysis of harmonic components in the power system based on a deep learning (DL) framework is introduced. In the proposed method, both amplitudes and phases of the harmonic components can be estimated accurately, unlike most of the research work in the literature, which usually focus on estimating amplitudes only. A convolutional neural network (CNN) structure is used to estimate the phases and amplitudes of harmonics, although CNN is usually used for classification. It has been shown that the proposed DL-based method can satisfactorily estimate both amplit ...More

Determination of Harmonic Current Responsibility at Point of Common Coupling of the Electrical System by Correlation of Voltage and Current Signals

Özgül SALOR-DURNA

In this study, the harmonic current responsibilites of the utility and the loads at the point of common coupling in the electrical system with the correlation analysis of measured current and voltage signals is discussed. Using the correlation coefficient obtained by correlation analysis, it is possible to determine who is responsible of which harmonic frequecy component, the loads or the utility. In PSCAD / EMTDC computer simulation, current and voltage signals obtained by preparing different circuit diagrams are processed in MATLAB environment and the accuracy of the simulation results are t ...More
