Electrical power quality (PQ) data is one of the prevalent types of engineering data. Its measurement at relevant sampling rates leads to large volumes of PQ data to be managed and analyzed. In this paper, an extensible database architecture is presented based on a novel generic data model for PQ data. The proposed architecture is operated on the nationwide PQ data of the Turkish Electricity Transmission System measured in the field by mobile PQ monitoring systems. The architecture is extensible in the sense that it can be used to store and manage PQ data collected by any means with little or no customization. The architecture has three modules: a PQ database corresponding to the implementation of the generic data model, a visual user query interface to enable its users to specify queries to the PQ database and a query processor acting as a bridge between the query interface and the database. The operation of the architecture is illustrated on the field PQ data with several query examples through the visual query interface. The execution of the architecture on this data of considerable volume supports its applicability and convenience for PQ data.

Design and realization of A 0.5-5 GHz cascaded feedback amplifier
Korkmaz, İbrahim Cem; Koç, Seyit Sencer; Department of Electrical and Electronics Engineering (2015)
Wideband amplification is one of the most examined study areas in microwave engineering. In this thesis work, 2-stage amplifier operating in decade bandwidth of 0.5-5 GHz is designed, simulated and demonstrated using two different discrete transistors. Designed amplifier is based on cascaded feedback amplifier concept. In order to flatten the gain of the designed amplifier, feedback topology is applied to both stages. Primarily, first stage is designed and demonstrated with flat gain of 7.8±1.2 dB and minim...
A New Index for Voltage Quality Assessment at Distribution Systems
KARACELEBİ, Mert; ERCİN, Özden; Göl, Murat (2018-09-07)
Analysis of power quality problems in distribution systems is getting important day-by-day because of the increase in vulnerable non-linear loads, such as data centers across the Globe. Regulatory authorities all over the world investigate these problems in order to serve in better conditions to the users. In this article we analyzed power quality problems in terms of their effects to the users, and developed an index to observe the problematic areas. As different types of loads in terms of operation critic...
An attempt to classify Turkish district data : K-Means and Self-Organizing Map (SOM) algorithms
Aksoy, Ece; Işık, Oğuz; Department of Geodetic and Geographical Information Technologies (2004)
There is no universally applicable clustering technique in discovering the variety of structures display in data sets. Also, a single algorithm or approach is not adequate to solve every clustering problem. There are many methods available, the criteria used differ and hence different classifications may be obtained for the same data. While larger and larger amounts of data are collected and stored in databases, there is increasing the need for efficient and effective analysis methods. Grouping or classific...
An improved data acquisition system for contactless conductivity imaging
Çolak, İlyas Evrim; Gençer, Nevzat Güneri; Department of Electrical and Electronics Engineering (2005)
The previous data acquisiton system developed for the electrical impedance imaging via contactless measurements is improved to obtain measurements with a faster scanning speed of 0.15 sec/mm2. This system uses magnetic excitation to induce currents inside the body and measures the magnetic fields of the induced currents with an axial gradiometer. Gradiometer consists of two differentially connected 10000-turn coils with diameter of 30 mm and a transmitter coil of 100-turn coil of diameter 30 mm placed and m...
Design of a web based interface and database structure for structural engineering experimental data /
Kurt, Tolga; Kurç, Özgür; Department of Civil Engineering (2014)
This study is conducted in order to design and implement a web-based database application which stores structural and earthquake engineering experimental data and related documents in a main server in a standardized manner and makes it possible for researchers and engineers to add and share experimental data easily. The system is developed in accordance with the standards defined in the scope of the SERIES project which is a project operated by a consortium consisting of related university laboratories and ...
