“…As a result of the analysis of existing methods for designing solar and hydroelectric power plants, it is incorrect to calculate the power of a combined plant based on the area of solar panels or the installed power of a hydro turbine generator [27] In a power plant based on renewable energy sources, it is impossible to produce electricity at full capacity. Installation of a hybrid solar and small hydro power plant at the designated site must be carried out based on the following requirements: -All electrical devices, circuit breakers and fuses, electrical equipment that protect against short circuits must be protected by a grounding device; -solar panels, the generator and its terminals, as well as the electric cable must be located in a place inaccessible to water; -When using a hybrid powertrain, the technical safety instructions must be observed.…”

This article discusses the development of a system for the combined use of solar and water energy based on a systematic approach to power supply. An improved physical model has been developed based on a model for predicting the production of electricity, taking into account the power and time of solar radiation, the amount and speed of water flow. At the same time, the share of electricity in the use of solar and water energy was determined simultaneously, depending on the conditions for the uninterrupted supply of consumers with the daily necessary electricity. The assessment of indicators of the combined use of solar and water energy and the definition of energy efficiency were developed by the authors on the basis of an increase in the share of electricity obtained from renewable energy sources in the electricity supply, which is explained by the coincidence of theoretical and experimental results.

“…One of the most important challenges in the world today is related to sustainable energy production, reducing the use of fossil fuels and preventing the increase in pollution and carbon dioxide emissions. Therefore, researchers are encouraged to conduct research on the use of clean and renewable alternative energy sources such as hydro, solar, wind and geothermal energy [1][2][3][4][5][6][7][8]. The use of water energy has been one of the most important sources of electricity generation for several hundred years, first it was used to obtain mechanical energy for mills, and then to generate electricity [9,10].…”

This article considers the main methods of regulating water consumption and power of micro hydroelectric power plants. New technical solutions for screw jet turbines adapted to low pressures and water flow rates are proposed. The Archimede’s screw turbine is a cost-effective and environmentally friendly microhydropower technology that operates at high efficiency at low pressure and medium flow rates. In this case, the change in power depends on the following parameters: the number of blades, water flow, the angle of inclination of the blades and the height of the pressure. Preliminary calculations carried out by the authors show that the power of a microhydroelectric power station depends on individual factors of the area. With an increase in the speed of the water flow, the speed of the water wheel also increases, and in turn, the electric power of the microhydroelectric power station increases.

Assessment of effect of lining material on energy efficiency of starting up ball mills

The article presents the possibility of increasing the service life of mill lining. Special attention is paid to the use of rubber linings for mills. A mathematical model of the asynchronous motor of ore grinding mills has been developed, i.e., the moment of resistance is shock. A system of equations for a synchronous motor of a mill plant for the d and q axes is described. Based on mathematical modeling of mill plant operating modes, it was determined that the corrosion coating prolongs the mill's service life, and the transition time is reduced to 10%.
