A complexly method of GIS technologies and models used in the development of environmentally modes of hydraulic and hydropower facilities in Uzbekistan

The expediency of creating a universal service center (USC) in a specific agricultural region has been revealed hereby. Its tasks have been substantiated as an executive of technical services. Basing on the formulated tasks, the structure of the operation of the USC has been developed within the framework of the system “Plant – service executive – consumer of the service”. The methods for determining the rational location of the USC in the territory of a particular region have been developed and implemented. An example of calculation of the functioning parameters of a universal service center has been presented. It was revealed that the economic effect of the USC would be achieved by reducing the route of mobile service workshops in the process of providing services to cars.

“…For a period of time t, the PS supplies W (thousand m 3 ) of water and consumes the amount of electricity directly for water uplifting is shown in the formula (4). Ev=е*W, kW/h, (4) where Ev is the consumption of electricity PS for the period t. The existing methods for determining the optimal option for the development of energy systems recommend conducting comparative calculations by comparing the reduced costs for the modernization and operation of energy facilities [11,12]. Reduced costs (Zpr) are calculated by the expression (5):…”

The purpose of this research is to improve the system of water resources management and operation of water facilities, reduce the energy consumption of irrigation pumping stations, which is one of the urgent modern problems in the Republics of Central Asia. The authors decide on the choice of such a set of subsystems and elements from the universal set, in which the value of the design parameters is provided with minimal costs. The recommendations developed by the authors use methods for monitoring the energy efficiency of hydraulic systems and are aimed at reducing electricity consumption, primarily through effective methods for regulating the operation of pumping stations. The main feature of assessing the technical condition of the units of pumping stations is the use of diagnostics of the dynamic level of elements of hydraulic units during operation. Monitoring of operating parameters of pumping stations was carried out on two pilot canals according to special tables of basic parameters. As an optimality criterion, options are accepted that differ in terms of reconstruction, duration of development of the capacity of electrical networks, interface structures of pumping stations, taking into account the time factor. By carrying out these activities, the water supply of the irrigation array will increase and crop yields will increase. After analyzing the data obtained, it will be possible to make a decision on the further use or modernization of the units of pumping units and structures. At the same time, the conditions for energy efficiency and reliability of the operation of the PS will improve.

In this article, we also consider the results of studying the problems and prospects for the use of educational and research stands of the Department of Hydropower and Hydraulics and information technologies to provide modelling of physical processes and environmental monitoring. This will improve the methodology for the education of energy engineers to implement the program of measures for the further development of energy and renewable energy in Uzbekistan. As an example of such an approach, we can consider as one interconnected System that combines the results of work: Examples of methods for creating a virtual stand based on digital maps for information support of environmental monitoring of hydraulic structures; An example of an experimental stand for research on the operation of structures made of reinforced soil; Examples of stands for the study of hydraulic processes - an example of the development of instruments for hydrometric support. Experimental stands are given. Methods for creating hydrostatic pressure and own weight of the dam. Conclusions and recommendations based on the results of experimental research on educational research stands.
