Abstract

Further development of hydropower as a source of renewable energy is an important factor for the world economy. As the hydro potential of large rivers in Ukraine is almost exhausted, one of the relevant ways to increase hydropower production is to complete the construction of existing and design new hydropower and pumped storage plants. In IMEP of NASU, with the help of modern numerical methods, two variants of the radial-axial pump-turbine runners of different specific speeds for heads of 80–120 m were designed, which meet the conditions of promising PSPs of Ukraine. The aim of the work was to obtain and analyze the energy characteristics in the turbine and pump modes of the two developed variants of the pump-turbine runners and evaluate the possibility of their application at promising PSPs of Ukraine. An experimental study was conducted at the hydrodynamic stand and energy characteristics were determined in a wide range of operation. The blade elements of the models for the experimental study were made of PLA plastic on a 3D printer. Experimental studies have confirmed the high theoretical energy performance of the developed flow parts. The best characteristics in both turbine and pump modes are obtained on the model with a higher specific speed. Based on the results of the research, a conclusion was made on the compliance of the obtained characteristics of the models with the requirements for the development of pump-turbines to the parameters of promising PSPs of Ukraine.
