Abstract
The experience gained in the 1960s and 1990s in operating small hydroelectric power plants shows that hydraulic structures, primarily water intake structures, are the most vulnerable part of hydropower nodes.
One of the promising areas of development of hydropower potential is the use of water runoff from small mountain rivers, which, as a rule, are located in the locations of electricity consumers. These structures are designed without taking into account the significant intra-daily fluctuations in river flow, which are insufficiently studied.
Therefore, it is necessary to carry out work aimed at improving water intake facilities in winter. Within the framework of this article, studies have been conducted on various options for passing sludge: through the ridge of the double shutter of the washer, through the side and bottom openings of the automatic shutter at the upstream level, as well as through a special hole in the discharge threshold of the structure. The data obtained, calculations and design of an automated water intake facility for derivational hydroelectric power plants will be used in the implementation of the project for the construction of at least 20 small hydroelectric power plants on the mountain rivers of southern Kazakhstan.
The analysis of the shortcomings of the existing structures of water intake facilities made it possible to develop a new design of a water intake facility for derivational hydroelectric power plants, for which a patent of the Republic of Kazakhstan was obtained.
