KARADENİZ BÖLGESİNDE YER ALAN DERELERDE KURULABİLECEK HİDROELEKTRİK SANTRALLERE (HES) UYGUN TÜRBİN SEÇİMİ VE GÜÇ HESAPLARI

Öz

Çalışmada, Karadeniz Bölgesindeki belirli derelerin hidroelektrik enerji potansiyeli incelenmiştir. Bölgenin coğrafi özellikleri ve derelerin hidrografi verileri temel alınarak Trabzon, Artvin, Giresun ve Rize illerinden seçilen toplam 16 dere için özgül hız ve türbin devir sayısı hesaplanmıştır. Ayrıca, bu dereler üzerine kurulması planlanan hidroelektrik santrallerin kurulu güçleri de belirlenmiştir. Giresun’un Bulancak ilçesinde yer alan Kızılev deresi 105 m net düşüye sahipken Tokmadin deresi 245 m düşüye sahiptir. Derelere ait özgül hız değerleri sırasıyla 227.77 d/d ve 59.87 d/d’dır. Rize’nin merkezinde yer alan Kokasor ve Askaroz derelerinin net düşüşleri aynı olup 105 metredir. Debileri ise sırasıyla 4.03 m 3 /s ve 6.26 m 3 /s’dir. Kokasor deresinde kurulması planlanan hidroelektrik santralin gücü 3707.26 kW iken Askaroz deresinin gücü 5758.67 kW’tır. Bu veriler, dere üzerinde kurulması planlanan hidroelektrik santralin, akışkan debisi ve net düşü değerinin yüksek olması durumunda maksimum kurulu güce ulaşılabileceğini göstermektedir.

SELECTION OF SUITABLE TURBINES AND POWER CALCULATIONS FOR HYDROELECTRIC POWER PLANTS (HES) THAT CAN BE ESTABLISHED IN THE STREAMS LOCATED IN THE BLACK SEA REGION

Abstract

In this study, the hydroelectric energy potential of certain streams in the Black Sea Region was investigated. Based on the geographical characteristics of the region and hydrographic data of the streams, specific velocity and turbine speed were calculated for a total of 16 streams selected from Trabzon, Artvin, Giresun and Rize provinces. In addition, the installed capacity of the hydroelectric power plants planned to be built on these streams was also determined. Kızılev stream in Bulancak district of Giresun has a net fall of 105 m, while Tokmadin stream has a fall of 245 m. The specific velocity values of the streams are 227.77 rpm and 59.87 rpm, respectively. Kokasor and Askaroz streams in the center of Rize have the same net fall of 105 meters. Their flow rates are 4.03 m 3 /s and 6.26 m 3 /s respectively. The power of the hydroelectric power plant planned to be built on Kokasor stream is 3707.26 kW, while the power of Askaroz stream is 5758.67 kW. These data show that the hydroelectric power plant planned to be built on the stream can reach the maximum installed power if the fluid flow rate and net head are high.
