Original abstract

The creation of highly efficient hydroturbines for lowhead microhydropower plants is considered. The use of uncontrolled (propeller) hydroturbines is a promising means of minimizing costs and the time for their recoupment. As an example, experimental results from Brno University of Technology are presented. The model axial hydraulic turbine produced by Czech specialists performs well. The proposed approach is experimentally verified at Moscow Power Engineering Institute. A model axial hydraulic turbine with four different rotors is designed for the research. The diameter of all four rotors is the same: 80 mm. The pipeline takes the form of a siphon. Working rotor R2, designed with parameter optimization, is characterized by the highest coefficient of energy utilization of the pressure pipeline and maximum efficiency. That confirms that the proposed approach is a promising means of maximizing the overall energy efficiency of the microhydropower plant.

Návrh vysoko účinných vodních turbín pro nízkospádové mikro vodní elektrárny. Použití neřízených (Propelerových) turbín je slibným prostředkem k minimalizaci nákladů a času pro pokrytí ztrát. Jako příklad jsou uvedeny experimentální výsledky z VUT v Brně. Model axiální hydraulické turbíny vyrobený českými odborníky funguje dobře.
