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 ...Более

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 ...Более
