Evaluation of energy efficiency using thermodynamics analysis in a hydropower plant: A case study

In this study, efficiency evaluation for Keban hydropower plant (KHPP), located in Elazig–Turkey, was performed both experimentally and numerically by using thermodynamic analysis. Turbine efficiency was measured with direct method by measuring temperature of turbine inlet and outlet. Theoretical analysis was performed using a computer code and employing the experimental data. A good agreement between the calculated and measured values was observed. The study shows that using thermodynamic method for determination of turbine efficiency is an effective and easy method in a hydraulic power plant.
