“…The available methods for manufacturing an Archimedean screw turbine have been studied [11][12][13][14][15]17], on the basis of existing methods, several studies were carried out to design and calculate the technical parameters of a turbine suitable for the water flow of the republic and test the developed device. Studies have shown that the Archimed screw turbine is excellently suited for low pressure hydropower applications and is particularly suitable for small sections of water flow.…”

“…Several parameters affect the efficient operation of an Archimedean screw turbine. These include: screw length, inner and outer diameters, angle of inclination, number of revolutions and flow rate [16,17]. The principle of operation of a screw turbine is that the propeller blades resist the pressure of water hitting the turbine blades and cause a decrease in water speed, this pressure rotates the turbine and drives the electric generator.…”

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.
