The interconnection project between Turkish grid and the ENTSO-E CESA system is almost finished. According to feasibility analysis based on computer simulations, inter-area oscillations around ∼0.15 Hz is expected once the interconnection is established. Unless countermeasures are taken, these oscillations could grow to dangerous amounts which will result in disconnection of Turkish grid from the interconnection. This paper analyzes the effect of such measures based on computer simulations. These measures are: 1) Parameter optimization of the governors of considerable size hydroelectric units in Turkey; 2) Parameter optimization of power system stabilizers (PSS), 3) Controller modification of static VAR compensators (SVC) existing in steel melting arc furnaces that are supplied directly from the transmission system, 4) Controller modification of ±50 MVAR STATCOM designed for voltage regulation, and 5) Application of breaking resistors The results illustrate the positive contribution of each measure to the damping performance of the system. The study includes conclusive recommendations.

Performance Based Seismic Evaluation of a 62 Story RC Tower in Istanbul Budak, Erhan; Sucuoğlu, Haluk (2018-06-18) A 62-story tall reinforced concrete office building with a free-standing height of 250 m has been designed in Istanbul in accordance with the new Turkish Earthquake Code (TEC, 2017). According to TEC 2017, buildings taller than 70 m and located in the first and second seismic zones are classified as tall buildings and these building shall be designed to meet the special rules based on performance-based seismic design approach. The tall building in Istanbul, having a parallelogram shaped floor plan and reinf...
Fully Integrated Ultra-Low Voltage DC-DC Converter with Voltage Quadrupling LC Tank Oscillator for Energy Harvesting Applications Jayaweera, H. M. P. C.; Tabrizi, Hamed Osouli; Muhtaroglu, Ali (2017-12-02) This paper presents a novel fully integrated ultra-low voltage DC-DC converter and its multi-stage architecture. DC-DC converter frequency has been analytically derived using model analysis and validated in Cadence environment. The proposed voltage quadrupling LC tank oscillator eliminates the buffer circuits utilized in the traditional DC-DC converter, hence improves the performance metrics such as efficiency and output power capacity. The circuit was designed in 180nm standard CMOS process and was simulat...
COMPARATIVE STUDY OF TURKISH EARTHQUAKE CODE 2007 AND TURKISH BUILDING EARTHQUAKE CODE 2018 Asgarov, İsmayıl; Kurç, Özgür; Department of Civil Engineering (2022-11-24) This thesis compares the complete analysis and design procedure of TEC 2007 and TBEC 2018 for an archetype reinforced concrete building with three different story configurations (three-story, six-story, twelve-story), and the structures are analyzed and designed at three locations in Türkiye (Istanbul, Ankara, Adana). The study focuses on the differences between the defined approaches in the mentioned codes regarding seismic load calculation, finite element model preparation, and reinforced concrete m...
Assessment of the effect of hydroelectric power plants' governor settings on low frequency inter area oscillations GENCOGLU, C; Tor, O.B.; Cebeci, E.; Yilmaz, O.; Güven, Ali Nezih (2010-10-28) The Turkish TSO (TEIAS) has been leading a project that aims the synchronous interconnected operation of the Turkish Power System and the ENTSO-E CESA (former UCTE) System. For this purpose, this study concentrates on the specific problems related to the electromechanical systems of large size hydroelectric power plants regarding low frequency inter area oscillations, which are prone to occur once the interconnected operation is established. The expected frequency of inter area oscillations after interconne...
Analytical study on seismic retrofitting of reinforced concrete buildings using steel braces with shear link Durucan, Cengizhan; Dicleli, Murat (2010-10-01) This paper is focused on a proposed seismic retrofitting system (PRS) configured to upgrade the performance of seismically vulnerable reinforced concrete (RC) buildings. The PRS is composed of a rectangular steel housing frame with chevron braces and a yielding shear link connected between the braces and the frame. The retrofitting system is installed within the bays of an RC building frame to enhance the stiffness, strength and ductility of the structure. The PRS and a conventional retrofitting system usin...
