This paper presents the design specifications and features of the automation system that is currently being applied to the distribution network of Istanbul. This system as a whole (software and hardware) has been designed, implemented, tested and integrated using the highest technology available complying with relevant international standards. The most prominent feature of the system is the capability of automatic fault detection and isolation on medium voltage feeders, a function which became a necessity with the decision of voltage uprating in medium voltage distribution in Istanbul. The system also provides distribution SCADA functionalities by utilizing fiber-optic cables as the communication medium. Being developed with an open system approach, the system could easily be extended to include other distribution automation functions.

Design and implementation of low leakage MEMS microvalves
Yıldırım, Ender; Külah, Haluk; Arıkan, Mehmet Ali Sahir; Department of Mechanical Engineering (2011)
This thesis presents analysis, design, implementation, and testing of electrostatically actuated MEMS microvalves. The microvalves are specifically designed for lab-on-a-chip applications to achieve leakage ratios below 0.1 at pressure levels in the order of 101 kPa. For this purpose, two different microvalves are presented in the study. In the proposed designs, electrostatic actuation scheme is utilized to operate the microvalves in normally open and normally closed modes. Characterization of normally open...
DEVELOPMENT OF AN AUTOMATIC DESIGN AND ANALYSIS TOOL FOR AXIAL FLOW COMPRESSORS
Kundes, Necmettin Anil; Aksel, Mehmet Haluk; Baran, Özgür Uğraş (2019-01-01)
This paper presents a new design and analysis tool that is developed to be employed during the design process of axial flow compressors. The tool chain implemented by this design tool consists of five parts: a mean-line design tool, followed by a blade geometry parametrization tool. Then 3D blade geometry is created, next a high quality structured mesh is generated and completed by Computational Fluid Dynamics (CFD) solution. All components employed in the new tool are either new developments, or achieved b...
Design, construction and control of an electrohydraulic load simulator for testing hydraulic drives
Akova, Hayrettin Ulaş; Platin, Bülent Emre; Balkan, Raif Tuna; Department of Mechanical Engineering (2014)
In this thesis, an electro-hydraulic load simulator is designed, constructed, and controlled in order to carry out the stability and performance tests of newly developed hydraulic drive and control systems. It is an experimental loading system capable of applying the desired test loads onto the actuator of the hydraulic drive system under test in a laboratory environment. The primary aim of this study is to support the research activities related to the development of hydraulic drive and control systems so ...
Design of a computer interface for automatic finite element analysis of an excavator boom
Yener, Mehmet; Söylemez, Eres; Department of Mechanical Engineering (2005)
The aim of this study is to design a computer interface, which links the user to commercial Finite Element Analysis (FEA) program, MSC.Marc-Mentat to make automatic FE analysis of an excavator boom by using DELPHI as platform. Parametrization of boom geometry is done to add some flexibility to interface called OPTIBOOM. Parametric FE analysis of a boom shortens the design stages and helps to find the optimum design in terms of stresses and mass.
DESIGN AND EVALUATION OF 2 BLOCK CODED MODULATION SCHEMES
SAYRAC, B; YUCEL, MD (1994-04-14)
Presents a study on the design and evaluation of two block coded modulation systems. One of the systems uses a binary construction and quadrature amplitude modulation. The other utilizes a ternary construction and phase modulation. The performance of the two coded schemes are compared theoretically with those of uncoded schemes of the same bandwidth, average power and transmission rate. The ternary scheme is also evaluated practically by computer simulations. Furthermore, the sub-optimum detection algorithm...
