A study on symbol synchronization and channel estimation for m-ary orthogonal transmission
Karagözlü, Eren; Tanık, Yalçın; Department of Electrical and Electronics Engineering (2011)
In this thesis, two key issues regarding M-ary orthogonal signaling systems, namely channel estimation and symbol timing recovery are investigated. Kasami codes, which are also called quasi orthogonal codes, are used for transmission of the information in place of orthogonal waveforms. In order to achieve symbol synchronization, a timing recovery scheme based on the Maximum Likelihood (ML) estimation of timing offset is proposed and the effects of proposed structure over the receiver performance are examine...

A Multi-criteria decision analysis approach to GIS-based route selection for overhead power transmission lines
Dedemen, Yiğit; Karslıoğlu, Mahmut Onur; Department of Geodetic and Geographical Information Technologies (2013)
Multi-criteria decision analysis (MCDA) techniques are popular to select the route of linear structures. In this study, Geographical Information Systems (GIS) is employed to assess all the criteria, which are requested to determine the preferable route of power transmission line (PTL). A MCDA model is established on the basis of the Analytic Hierarchy Process (AHP) and Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE). Because of the complexity of the routing problem, GIS and MCD...
Determination of optimum values for voltage setpoints of power stations in Turkey
Elma, İsmail; Güven, Ali Nezih; Tör, Osman Bülent; Department of Electrical and Electronics Engineering (2014)
Voltage control is performed in three hierarchical levels in Turkish power system: primary, secondary and tertiary voltage control. Primary and secondary voltage controls are defined as the regulation of the voltage at the generator terminal and at the high voltage busbar of the power plant according to the pre-determined setpoints. The determination of the voltage setpoints for the power plants, which is defined as the tertiary voltage control, is performed by the operators in National and Regional Load Di...
Optimal determination and allocation of secondary frequency control reserve in a market environment considering ACE criteria /
Geren, Ali; Güven, Ali Nezih; Tör, Osman Bülent; Department of Electrical and Electronics Engineering (2014)
Frequency control in Turkey is realized under four main tasks, namely; primary, secondary, tertiary frequency control and time control according to European Network of Transmission Operators for Electricity (ENTSO-E) regulations. As being a part of an interconnected electricity network, secondary frequency control mechanism, which is realized by the utilization of an Automatic Generation Control (AGC) System, plays a crucial role in the achievement of two important goals. One of them is maintaining the freq...
