“…This circumstance in the front chamber negatively affects the operating parameters of the pumps, their productivity decreases, the efficiency decreases, and the energy consumption increases. Observations have established that excessive sediment deposition in front of the suction pipelines leads to a decrease in the efficiency of the pump to 3.0 % [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

It has been determined that the reduction of siltation of the front chamber is necessary because the deposited sediments seriously violate the planned hydraulic structure of the flow when water is sucked up by pumps, as a result of which their efficiency decreases. The method of calculating the pipeline system of a new device designed to significantly reduce the siltation of the front chamber of irrigation pumping stations by artificially creating turbulence in the water flow in the bottom layer of the structure is presented. This calculation methodology is based on the use of the theory of flooded water jets, which makes it possible to determine the main characteristics of the jet. The latter allows calculating the design parameters of the pipeline system. The results of experimental studies are presented to compare the calculated data with the results of experiments, as well as to determine the effectiveness of the proposed device for a significant reduction in siltation of the front chamber of irrigation pumping stations.

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.
