摘要

本文致力于在可靠、廉价、刚性固定动导叶的无调管式螺旋桨水轮机的基础上进一步发展小水电。这种涡轮机主要用于低压小型水力发电站。它们的主要缺点是无法对产生的功率进行调节。然而,本文提出了最小化这一缺点的解决方案。建立了管状螺旋桨水轮机4个模型系列的矩阵。本矩阵中提出的水轮机的命名是为了改善小型水力发电厂的技术特性和减少它们对环境的负面影响。提出了200千瓦以下低压小型水力发电厂机台采用该模型的规则,并对其进行了技术和环境论证。根据本文的建议,在一个HPP上至少应安装来自同一型号线的两台相邻不同的涡轮机。最好的选择是三个不同的相邻的涡轮机从同一型号系列,但技术和经济分析应进行更详细的理由选择涡轮机的数量。这是我们进一步调查的主题。本文的科学和实践成果的应用将改善管状螺旋桨水轮机小型水电站的技术特性,并将其对下游流域河流动植物生命的负面影响降至最低。

Creation and substantiation of the matrix for model series of tubular propeller turbines for small hydropower plants
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.
