Considering the increasing number of electrified traction systems and changing technological advances in power electronics industry, it is required to successfully model electrified train systems. In this paper a DC catenary voltage model is proposed for a multi substation subway system. The proposed method is capable of simulating dynamic behavior of the train during different modes of operation. In this study, firstly, the electrical parameters of the system will be found to form distributed parameter model. In order to simplify analytic calculations, an approximate yet accurate solution method is proposed. Secondly, relations modeling voltage variation are linearized for improved computational performance. Finally, developed model is extended to multi substation case. Developed model is verified using real field data.

DC Catenary Line Modeling of Subway Systems Sezgin, Mustafa Erdem; Göl, Murat (2018-08-10) Today's technology and trend for clean energy, made electrified traction systems more and more popular around the world. As number and capacities of those systems increase, electrical modeling of those systems became a must for power quality studies and dynamic distribution system analysis. However, those models have inaccuracies due to electrical parameters and high computational burden. This paper proposes a linearized DC catenary line model for real subway systems, which has a little computational burden...
Condition monitoring and fault diagnosis of electrical motor drive systems Demirel, Aykut; Keysan, Ozan; Department of Electrical and Electronics Engineering (2019) Increasing utilization of electrical machines results in an increasing demand of high reliability and safety. Especially in mission critical applications, unexpected failures of these machines may bring irrecoverable damages to the systems. Furthermore, such failures may be hazardous to human life in military or aerospace applications. One method to meet the reliability and safety requirement is introducing redundant modules to be used in case of an emergency. However, adding extra modules as substitutes in...
Message scheduling for the static and dynamic segment of FlexRay : algorithms and applications Kızılay, Özgür; Schmidt, Şenan Ece; Schmidt, Klaus Verner; Department of Electrical and Electronics Engineering (2015) Today’s automobiles comprise an increasing number of electronic components. Some of these components are used for entertainment purposes and some of them are used for safety-critical application such as X-by-Wire that are implemented on electronic control units (ECUs). The safe data exchange among such ECUs has to be realized by a robust and reliable in-vehicle network protocol. In this context, FlexRay is one of the new generation in-vehicle network protocols which is already used in upper class series veh...
Feedback Motion Planning For a Dynamic Car Model via Random Sequential Composition Özcan, Melih; Ankaralı, Mustafa Mert (2019-01-01) Autonomous cars and car-like robots have gained huge popularity recently due to the recent advancements in technology and AI industry. Motion and path planning is one of the most fundamental problems for such systems. In the literature, kinematic models are widely adopted for planning and control for these type of robots due to their simplicity (control and analysis) and fewer computational requirements. Though, applicability of kinematic models are limited to very low speeds or some specific cases, which c...
Optimal mix of a solar, wind, and fuel cell hybrid residential system Chehab, Khalil; Fahrioğlu, Murat; Sustainable Environment and Energy Systems (2018-1) Nowadays, supplying electrical power using renewable energy systems faces problems due to the high cost and unreliability of those systems. With the variability of renewable energy sources, a possible way to provide electricity is by combining different renewable sources in one hybridized system. This study is about optimizing and testing the feasibility of different hybridized systems including solar, wind, and fuel cell systems. The study will include on-grid and off-grid optimal solutions for a case stud...
