“…The dynamic effect of the flow on the particle of the bottom soil determines the separation of the particle from the system of surrounding particles and its weighing by the flow. Currently, it is believed that the action of the following forces determines the weighing of particles of bottom soil [19][20][21][22][23][24][25][26][27][28][29][30]:…”

“…1. Studies carried out at RIWP with the participation of the authors have shown that the obtained ratios make it possible not only to use scientifically grounded methods for calculating the known intake structures of the PS (front chambers, water intakes), but also to analyze the design schemes of dynamic and kinematic flow supply conditions, which allow to establish the nature of the influence of flow parameters and soil particles of bottom and suspended sediments on the process of their layout [18,19]. 2.…”

Research is carried out for design institutes in which the structures of pumping stations are designed. In the regional conditions of the Republic of Uzbekistan, when operating pumping stations, the problem of protecting equipment from pumps and fin is of particular importance, as well as the stability of water supply structures and the creation of favorable hydraulic conditions for supplying flow to the pumps. The main factors in the flow conditions are the calculations associated with suspended particles. The purpose of the research was to study the kinematics of the flow of intake structures in the problem of protecting equipment from pumps and fin. The research subject was to identify the regularities of the operation of intake structures depending on the structure of the flow supply. Experimental methods of hydraulic research of intake structures of pumping stations are used in the work. The analysis of the current state of water supply to the intake structures of pumping stations is carried out based on calculation schemes, which make it possible to establish the nature of the influence of flow parameters and soil particles on this process.

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.

In our country, a lot of attention is paid to the development of the energy sector. A lot of work is underway to modernize existing capacities and commission new capacities. At the same time, the unit capacities of units and power plants also increase, which ensures faster commissioning of capacities in the power system and an increase in the efficiency of power plants. Attention is also paid to the development of power plants based on renewable energy sources (hydraulic, solar, wind, etc.). One of the most important tasks in the power industry is to cover peak minimum and maximum loads, which is becoming increasingly important in connection with the growth of the power system's capacity. As is known, according to world indicators, the maneuverable capacities should be about 25% of the total power of the EPS. The most promising maneuverable capacities are hydroelectric power plants. However, in our country, hydroelectric power plants account for about 14.3%. This task will become more complicated with the introduction of capacities based on solar and wind energy and the commissioning of new hydroelectric and thermal power plants in the Republic. This is because RES capacities have a significant discontinuity even during the day, and the water resources in the Republic are primarily for irrigation and drainage purposes and are significantly variable during the season. One way to solve these problems in the world is the creation and use of pumped storage power plants (PSPP). The peculiarities of the creation and use of pumped storage power plants in our region are that the available hydro resources of our region are mainly of water management importance, while the task is also to increase the energy efficiency of existing reservoirs. Based on the foregoing, we can say that the development of methods for determining the economic efficiency of pumped storage power plants, taking into account direct and indirect effects, taking into account the peculiarities of their use in energy and water management systems of Uzbekistan is the main task for the present time. To solve the set tasks, a new methodology and program for substantiating the technical and economic indicators of pumped storage power plants in Uzbekistan's energy and water management systems have been developed. The schemes of using pumped storage power plants at four energy and water management facilities, that is, the Tuyamuyun hydro subunit, Arnasai, Talimarjan, and Khodjikent reservoirs, were considered, and for these facilities, based on the developed methodology and program, their technical and economic parameters of the pumped storage power plant were determined. Based on the results obtained, it can be said that using the PSPP in four facilities, it is possible to generate a total of about 418 MW of capacity and more than 930.0 million kWh of electricity, as well as to save 139 thousand tons of fuel equivalent per year, with this, the annual economic efficiency will be about 700.0 billion sums.
