摘要：Nowadays hydraulic and power installations can be defined as power installations that are well-designed in terms of construction and technology and working on renewable energy resources (RER). However wide use of such power stations is interfered by their low performance in comparison with thermal stations, using organic fuel. The purpose of the conducted research in this article is – search of ways to increase the competitiveness of power stations, using RER, in comparison with traditional power stations. In order to achieve the specified purpose the authors solved the following tasks: they analyzed and developed new constructive solutions of the power stations using RER; they developed the power-economic viability method for the choice of key parameters of the power stations working on RER. The researchers also gained the set objectives, using theoretical and experimental methods of calculation connected with physical modeling, the theoretical analysis and use of an economic case of the made decisions. Thus, carried-out analysis of designs of the power stations, based on RER allowed to develop a method of efficiency enhancement of these installations and to solve a problem of wider use of power stations as a part of the installations working on RER. The provided technical solutions of power stations that give the chance to develop new suggestions for improvement of designs of power stations, based on RER and to promote development of recommendations about their competitive recovery. As a result it will allow to create conditions for production of the effective national power stations, based on RER, and cumulative scientific and technical potential, that can be used for further development of nonconventional wind power and hydropower both in Russia, and abroad.
