Research and development of a gravitational water vortex micro-HPP in the conditions of Kyrgyzstan

The field of research in this article is small-capacity hydropower conversion plants. The object of the study is the turbines of low-pressure micro hydro power plants ( micro HPP) that convert the energy of velocity head into electrical energy. The purpose of the study is to study the features of th...

description The field of research in this article is small-capacity hydropower conversion plants. The object of the study is the turbines of low-pressure micro hydro power plants ( micro HPP) that convert the energy of velocity head into electrical energy. The purpose of the study is to study the features of the operation of rotary turbines and determine the dependence of the rotational speed on the load and efficiency. The influence of the central gap in the turbine blades on its efficiency was also evaluated. During the research, the results of three-dimensional modeling of three types of hydraulic turbines using the Kompasflow software product and the results of experimental studies obtained on a specially created hydraulic stand were used. Based on the results obtained, it was found that, regardless of the types of turbines under consideration, the rotational speed decreases with increasing load, and there is a certain load interval at which the maximum efficiency is achieved. The presence of a central gap in the turbine blades does not lead to a significant increase in the efficiency of the turbine.
