The paper is devoted to further development of small hydropower on the basis of reliable and cheap unregulated tubular propeller hydroturbines with rigidly fixed operating and guide blades. Such turbines are used mainly at low-pressure small hydroelectric power stations. Their main drawback is the impossibility of generated power regulation. However, solutions that minimize this shortcoming are proposed in this paper. Matrix of 4 model series of tubular propeller hydroturbines has been created. The nomenclature of turbines presented in this matrix is aimed at improving technical characteristics of small hydropower plants and reducing their negative impact on the environment. The rules for equipping machine platforms of low-pressure small hydroelectric power plants with capacity up to 200 kW with models of turbines from the created matrix are proposed, and their technical and environmental justification is performed. According to the recommendations given in the paper, at least two different adjacent turbines from the same model line should be installed at one HPP. The best option is three different adjacent turbines from the same model series, but technical and economic analysis should be performed for more detailed justification of the choice of the number of turbines. This is the subject of our further investigations. The application of scientific and practical results presented in the paper will improve technical characteristics of small hydropower plants with tubular propeller turbines and minimize their possible negative impact on the life of river flora and fauna in lower basin.
