As industrialization and automation processes continue to expand, power quality parameters and voltage sags in particular become more important. Sensitive equipment trips due to voltage sags cause enormous financial loss in the industrial sector. Consequently, in consultation with AF Turkey, Trakya Electricity Distribution Company (TREDAS) began an R&D project on voltage sags funded by the Turkish Energy Market Regulatory Authority (EMRA). The project aims to characterize voltage sags and perform research into sag mitigation methods. In this paper, the results of the simulation studies of a feeder located in the Thrace region are presented. The effects of short circuit faults on the development of voltage sag events and utility-side mitigation methods are analyzed through computer simulations using EMTP-RV software. Furthermore, definitions of voltage sag indices according to IEEE Std. 1564-2014 are given and the methods used to minimize the effects of voltage sags are explained.

Performance of Electrical Power Flow Solvers: Case Studies
Ceylan, Özgün Ada; Uğur, Ömür; Department of Scientific Computing (2022-2-9)
Advancing technologies in distributed electrical generation and increasing amount of required electricity make electrical systems more complicated. Thus, the number of buses has increased and the size of incidence matrix for electrical power flow calculation has expanded. Hence, investigation and performance analysis on different solvers are needed. In this thesis, a performance comparison between iterative solvers for electrical power flow is studied. These solvers are Newton-Raphson, Fast-Decoupled and N...
Solving optimal control time-dependent diffusion-convection-reaction equations by space time discretizations
Seymen, Zahire; Karasözen, Bülent; Department of Mathematics (2013)
Optimal control problems (OCPs) governed by convection dominated diffusion-convection-reaction equations arise in many science and engineering applications such as shape optimization of the technological devices, identification of parameters in environmental processes and flow control problems. A characteristic feature of convection dominated optimization problems is the presence of sharp layers. In this case, the Galerkin finite element method performs poorly and leads to oscillatory solutions. Hence, thes...
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 ...
Analysis and Control of Complex Flows in U-Bends using Computational Fluid Dynamics
Guden, Yigitcan; Yavuz, Mehmet Metin (2014-08-07)
Analysis and control of flow structure in U-bends are crucial since U-bends are used in many different engineering applications. As a flow parameter in U-bends, the ratio of inertial and centrifugal forces to viscous forces is called as Dean number. The increase of Dean number destabilizes the flow and leads to a three-dimensional flow consisting of stream wise parallel counter-rotating vortices (Dean vortices) stacked along the curved wall. Due to the curvature in U-bends, the flow development involves com...
IMPLEMENTATION OF STRONG LIGHT-MATTER INTERACTION FOR FABRICATION AND LIGHT MANAGEMENT OF THIN CRYSTAL SILICON SOLAR CELLS
Zolfaghari Borra, Mona; Bek, Alpan; Ünalan, Hüsnü Emrah; Department of Micro and Nanotechnology (2021-7-29)
The integration of photonic components with electrical elements on the same silicon chip may lead to the development of new technologies. One limitation is the space available on the wafer surface, which is restricted. Currently, conventional fabrication techniques produce devices only on the top thin layer of the wafer surface. As a result, new architectural designs are required. Producing functional components deep inside Si without creating damage to the surfaces is a potential technique for overcoming t...
