Power quality issues of heavy industry, especially iron and steel plants, require special solutions. High levels of harmonic currents, unbalanced operation and light flicker arising from rapid fluctuations of active and reactive power demands are common problems in these plants. Almost all of these plants in Turkey are equipped with modern Static Var Compensator (SVC) Systems. In this thesis, alternative control strategies and flicker compensation system topologies are investigated and evaluated based on real-time field data and compared with the existing SVC systems. It is found out that the currently installed SVCs are not fully capable of solving the power quality issues of EAFs. This thesis is dedicated to detailed analysis, design, control, and simulation of TCR based SVC using instantaneous power theory, Three Phase Bridge Connected STATCOM and Delta Connected STATCOM. These 3 different types of compensators are modelled based on the similar installed capacities and their contribution to voltage quality and reactive power compensation are compared.

An examination of the legislative framework for supporting the renewable tariffs
Akca, Alper; Sevaioğlu, Osman; Department of Electrical and Electronics Engineering (2008)
Sustainability and environmental concerns are critical issues in energy sector. Limited availability of fossil resources, environmental pollution caused by the greenhouse gases emitted as a result of fossil fuel usage and safety issues of nuclear power plants cause the seek of new resources in energy industry. Renewable energy sources emerge as the alternative energy resources for the industry. The unlimited availability of most of the renewable resources meets the sustainability needs in the energy sector....
Design and implementation of a voltage source converter based hybrid active power filter
Uçak, Onur; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2009)
This research work is devoted to the analysis, design and implementation of a shunt connected Hybrid Active Power Filter by the use of a lower rated voltage source PWM converter, and a series connected LC passive filter. In recent years, voltage and current harmonics have become a serious problem both in transmission and distribution systems, due to the widespread usage of non-linear loads such as diode/thyristor rectifiers, electric arc furnaces and motor drives. In order to obtain a better performance tha...
A Case Study on Feasibility Assessment of Small Hydropower Scheme
Korkmaz, Ozan; Yanmaz, Ali Melih; Tiğrek, Şahnaz; Department of Civil Engineering (2007)
Feasibility studies concerning decision-making for various types of items to be used in a small hydropower scheme is important for estimating the energy generation, the approximate cost of the project, and the required budget allocation. A computer program named RETScreen, which is commonly used in the North Americas, is capable of evaluating the energy generation, investment and maintenance costs for small hydro-projects. This thesis is based on application of this program to the Turkish practice. To this ...
A new field-data based eaf model applied to power quality studies
Göl, Murat; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2009)
Electric Arc Furnace (EAF) modeling has been a common research area to date. This thesis work proposes a new field-data based EAF-specific model. The data used in developing the proposed model is obtained from field measurements of instantaneous voltages and currents of EAF the plants. This model presents the dynamic behavior of the EAF system including all its parts, which are the EAF transformer, the secondary circuit, the electrodes moving and the arc itself. It consists of a cascade connected variable-r...
Analysis of the VIT1 Promoter Activity in Developing Arabidopsis thaliana Plants
Eroğlu, Seçkin (2021-10-01)
Iron (Fe) deficiency in plants is one of the widespread problems limiting agricultural production. Generating crops more tolerant to Fe deficiency by genetic engineering or breeding is of great interest but challenging due to the knowledge gaps in general plant Fe homeostasis. Although several genes involved in Fe homeostasis have been identified, characterization of their roles is mainly limited to specific organs at specific developmental stages of the plant, where their mutants show the most striking phe...
