A New Sequential AC-DC Power Flow Algorithm for Multi-Terminal HVDC Systems

Yalçın, Faruk; Arifoğlu, Uğur (WILEY, 2017)

This paper presents a new algorithm based on the sequential method for power flow calculation in integrated multi-terminal, high-voltage, direct current (HVDC) systems. Unlike similar studies in the literature, a real ...
A new sequential power flow algorithm for AC/DC systems including independent multiterminal DC subsystems

Yalçın, Faruk; Arifoğlu, Uğur (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2017)

This paper presents a new algorithm based on the sequential method for power flow calculation in multiterminal AC/DC systems. The proposed approach differs from other similar studies in the literature by handling two main ...
Crack insertion, meshing and fracture analysis of structures using tetrahedral finite elements

Nart, Ergün; Ayhan, Ali Osman (ELSEVIER, 2011)

In this study, a method and corresponding tools are presented to insert a three-dimensional crack of a given size and location into a finite element model without any cracks using fully unstructured finite elements. For ...
Development of A Wearable Exercise Device for Rehabilitation of Hemiplegic Hand

Serbest, Kasım; Mustafa Zahid Ylidiz; Çilli, Murat; Karayel, Durmuş; Tekeoğlu, İbrahim; Eldoğan, Osman; Y Isler (IEEE, 2016)

Millions of people suffer a stroke each year. One of the problems after stroke is hemiplegic hand. In previous studies a lot of robotic based devices has been suggested for rehabilitation of hemiplegic hand. Actuators using ...
Investigation of carburising treatment of injector flange in diesel engine

Nart, Ergün; Genel, Kenan (ELSEVIER SCI LTD, 2010)

The applicability of carburising treatment of injector flange in a diesel engine was investigated. Initially, a carburized case structure made of low-carbon (0.23%) steel was approximately modelled by five sub-regions. ...
Modeling and Analysis of the Weld Bead Geometry in Submerged Arc Welding by Using Adaptive Neurofuzzy Inference System

Karayel, Durmuş; Özkan, Sinan Serdar; Oğur, Ahmet; Topal, Bayram (HINDAWI PUBLISHING CORPORATION, 2013)

This study is aimed at obtaining a relationship between the values defining bead geometry and the welding parameters and also to select optimum welding parameters. For this reason, an experimental study has been realized. ...

Optimal reactive power flow solution in multiterminal AC-DC systems based on artificial bee colony algorithm

Yalçın, Faruk; Arifoğlu, Uğur (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2014)

Active power loss optimization is one of the important goals in electrical power systems and it is provided by optimal reactive power flow (ORPF). In this study, a new approach for the solution of the ORPF in multiterminal ...
Robust single-phase inverter based on the buck-boost converter through an efficient hybrid control

Yalçın, Faruk; Arifoğlu, Uğur; Yazıcı, İrfan; Kenan Erin (INST ENGINEERING TECHNOLOGY-IET, 2020)

This study presents a new and robust single-phase inverter based on the buck-boost converter. The proposed inverter topology has minimised numbers of active and passive elements that provide less complexity and cost. Unlike ...
