Electrical power quality (PQ) data is a ubiquitous type of engineering data quantified as a set of PQ parameters, such as frequency, flicker, and harmonics, obtained from electricity transmission and distribution systems. For PQ problems detected as deviations from nominal power system behavior negatively affect the workings of governmental and industrial institutions, as well as the electronic equipment and the psychology of individual humans, several systems of varying complexities to measure and monitor PQ parameters have been developed in order to detect the problems and take the necessary countermeasures. Yet, the domain of PQ data still suffers from the lack of a common vocabulary to be shared by the involved parties. In this paper, a novel domain ontology for electrical PQ, called PQONT, is presented to fulfill this need. Relevant standards and regulations have been utilized extensively during the ontology building process. The proposed ontology also supports linguistic applications by providing a number of linguistic properties applicable to all of its concepts. This facility of the ontology is employed in a multilingual natural language based interface for PQ data collected through a nationwide PQ measurement system so that the data can be queried in a flexible way. The implementation details of the interface is presented with a couple of query examples to illustrate the contribution of the ontology to a real application. The future work includes the extension of PQONT to a more general power system ontology so that it can contribute to a wider range of applications in the power system domain.

Investigation of multilevel inverters for d-statcom applications Deniz, Mustafa; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2009) The most important advantages of Multilevel Inverters are the absence of a coupling transformer for medium voltage applications and low harmonic current content. In this way, relocatable and economical STATCOM systems can be realized. Complex control algorithms and the isolation problems of measurement devices and power supplies are the main challenging parts of this type of application. In this study, the design, realization, and the performance of a Voltage Source Type Cascaded Multilevel Converter Based ...
Modular Heat Sinks for Enhanced Thermal Management of Electronics Hoque, Muhammad Jahidul; Günay, Ahmet Alperen; Stillwell, Andrew; Gurumukhi, Yashraj; Pilawa-Podgurski, Robert C. N.; Miljkovic, Nenad (2021-06-01) Power electronics are vital for the generation, conversion, transmission, and distribution of electrical energy. Improving the efficiency, power density, and reliability of power electronics is an important challenge that can be addressed with electrothermal codesign and optimization. Current thermal management approaches utilize metallic heat sinks (HSs), resulting in parasitic load generation due to different potentials between electronic components on the printed circuit board (PCB). To enable electrical...
Nationwide real-time monitoring system for electrical quantities and power quality of the electricity transmission system Demirci, T.; Kalaycioglu, A.; Kucuk, D.; Salor, O.; Guder, M.; Pakhuylu, S.; Atalik, T.; Inan, T.; Cadirci, I.; Akkaya, Y.; Bilgen, S.; Ermiş, Muammer (2011-5-01) In this study, a nationwide real-time monitoring system has been developed to monitor all electrical quantities and power quality (PQ) parameters of the electricity transmission network including its interfaces with the generation and distribution systems. The implemented system is constituted of extended PQ analysers (PQ(+) analysers), a national monitoring center for power quality (NMCPQ), and the PQ retrieval and analysis software suite. The PQ(+) analyser is specifically designed for multipurpose usage ...
Online characterization of interharmonics and harmonics of AC electric arc furnaces by multiple synchronous reference frame analysis Uz Loğoğlu, Eda; Salor, Özgül; Ermiş, Muammer (2015-10-18) 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 two -fold; deep understanding of the EAF characteristics, and fast and accurate ...
SPAMM Based Dual Current Injection to Accelerate Data Acquisition in Magnetic Resonance Electrical Impedance Tomography Naji, Nashwan; Sümser, Kemal; Eyüboğlu, Behçet Murat (2017-04-27) Reducing acquisition time in magnetic resonance electrical impedance tomography (MREIT) improves signal to noise ratio and temporal resolution of measured conductivity data. On the other hand, the reconstruction accuracy of MREIT can be improved by acquiring multiple data using different current injection patterns, which in turn increases the total scan time. In this study, a novel pulse sequence is proposed to reduce the scan time in MREIT by injecting two current patterns in a single acquisition. This met...
