In this study, the electricity production and energy costs of hydroelectric power plant is analyzed by using actual plants data. Using long term data, capacity utilization rates were estimated on an hourly basis. Economic analysis factors affecting (initial investment cost, operating-maintenance costs, etc.) researched assessed in detail. Additionally, for first time a dimensionless number was ...

At low flow rate operation, Francis turbines feature a cavitating vortex rope in the draft tube resulting from the swirling flow of the runner outlet. The unsteady pressure field related to the precession of the vortex rope induces plane wave propagating in the entire hydraulic system. The frequency of the vortex rope precession being comprised between 0.2 and 0.4 times the turbine rotational s...

The present work is in the framework of water resource control and optimization. Specifically, an advanced process system was designed implemented a hydroelectric power plant for management. Two reservoirs (connected through regulation gate) set turbines energy production constitute main elements process. In-depth data analysis carried out to determine variables major issues related previous co...

Hydro resources take the first place among natural of Western Georgia. The Enguri and Rioni rivers are largest energy ones. Black Sea basin rivers, particularly characterized by waterlogging, high fallout, fast currents potential. It is clear, in future, demand for electricity western Georgia will be balanced growth hydropower plants, safe construction, which allow us to export some abroad stre...

Utilization of renewable energy sources is a necessity to reduce the consumption fossil sources. On end 2021, it was reported that world experiencing an crisis, so use being something urgent. Renewable power generation can be done in large scale small even on household level. Electrical independence achieved, one way by utilizing available surrounding house. Several utilized around house includ...
