Abstract
The structure of hydraulic structures of power and water management systems includes gates for various purposes, which allow you to regulate and distribute the flow of water in channels and waterworks. Existing gate designs do not provide for the possibility of generating electricity from the water energy of the stream passing through them. In order to convert the hydraulic energy of water passing through the gates into electrical energy a new patented design of the gate is proposed which allows using micro-hydroelectric power plants with a Banki turbine to make more rational use of the hydro resources of energy and water management systems. The proposed design solves the problem of expanding the functionality of the gate and increasing the efficiency of micro-hydroelectric power plants with a reduction in its cost. Areas of application of the new design for the combined use of micro-hydroelectric power plants and hydraulic gates at hydroelectric power systems are also proposed. The technique for determining the technical and economic parameters of micro-hydroelectric power plants installed on flat gates of hydraulic structures is given, and theoretical calculations are performed, which showed that the higher the capacity of micro-hydroelectric power plants, the shorter its payback period.
Highlights
In the development of one of the renewable energy sources, i.e. hydropower industry of the Republic of Uzbekistan, one of the important places is occupied by the use of energy potential of rivers, canals, water intake facilities, outfall and discharge facilities of reservoirs and other facilities for energy and economic purposes [2, 3, 4, 5]
The relevance of the topic of the article lies in the fact that currently in the water system of the republic there are several tens of thousands of gates installed at culverts, spillways and regulated hydraulic structures of waterworks, irrigation canals, reservoirs, pumping stations [2, 3, 4, 14, 15, 16] and the installation of micro-hydroelectric power stations on them will allow more fully use the hydropower potential
We have proposed a method of using water energy from a stream passing through a structure in the form of a new patented micro-hydro power plant design with Banks on flat gates of a hydraulic structure [20], which will allow more rational use of energy systems

Operated gates of hydraulic structures are designed to open or close the spillway, water distribution in irrigation channels, etc These gates are used in all hydroelectric and water management facilities and have various design versions: disk, flat, cone, etc. These gates are used in all hydroelectric and water management facilities and have various design versions: disk, flat, cone, etc. [2, 3, 4, 6, 8, 12, 17]
