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 interconnected operation is close to 0.15 Hz, which is in the frequency range of the speed governing structures of turbines, as explained in the first two sections of the thesis. In the third section, the nonlinear turbine governor model used throughout the study is explained. In the following part, the governor parameter tuning study with regard to the defined performance objectives is explained. Afterwards, the effect of the retuned governor settings of the sample hydroelectric power plants on a simple multi machine power system is shown. Following that, the system wide effect of removing the sources of negative damping, which are strongly dependent on the governor settings of the major hydroelectric power plants of the Turkish Power System, is shown. In the final part, conclusions are made on the operation of the hydroelectric power plants regarding the frequency stability of the system after synchronous interconnected operation of the Turkish Power System and the ENTSO-E CESA System.

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 effects of hydro power plants’ governor settings on the turkish power system frequency Cebeci, Mahmut Erkut; Ertaş, Arif; Department of Electrical and Electronics Engineering (2008) This thesis proposes a method and develops a mathematical model for determining the effects of hydro power plants’ governor settings on the Turkish power system frequency. The Turkish power system suffers from frequency oscillations with 20 30 seconds period. Besides various negative effects on power plants and customers, these frequency oscillations are one of the most important obstacles before the interconnection of the Turkish power system with the UCTE (Union for the Coordination of Transmission of El...
Discussion and evaluation of mining and environment laws of Turkey with regard to eu legislation Şafak, Şükrü; Bilgin, Hasan Aydın; Department of Mining Engineering (2006) Turkey is trying to become a member of the European Union. Within this frame, studies are proceeding for harmonization of the Turkish legislation with the EU legislation. European legislation might have positive or negative impact on the mineral extraction industry and national mining law. Since there is no title directly related to mining policy in the EU legislation the mining policy of EU was evaluated especially under the titles“energy” and “environment”. In this thesis, the Turkish mining regulations a...
Hydroelectric power potential and its use in Turkey Taşdemiroğlu, Erol (Elsevier BV, 1988-7) Hydroelectric development in Turkey is briefly reviewed. The results of estimates of gross and economically exploitable hydroelectric power potentials are compared. Dam sites and their order for construction are identified. Present and future developments in the power sector are analyzed and projections are given for electricity consumption and production to the year 2010. Hydraulic, thermal and nuclear contributions to total electricity generation are discussed. Finally, problems associated with hydroelect...
Four methods for short-term load forecasting using the benefits of artificial intelligence Erkmen, İsmet; Topalli, AK (Springer Science and Business Media LLC, 2003-09-01) Four methods are developed for short-term load forecasting and are tested with the actual data from the Turkish Electrical Authority. The method giving the most successful forecasts is a hybrid neural network model which combines off-line and on-line learning and performs real-time forecasts 24-hours in advance. Loads from all day types are predicted with 1.7273% average error for working days, 1.7506% for Saturdays and 2.0605% for Sundays.
