Abstract

The activity of farm enterprises is directly connected with the efficient use of resources such as electrical energy and water. Taking such conditions as factors of economic expediency and ecological safety into account, it is more reasonable to use wind stations in order to provide consumers with energy and water. The use of conventional wind and electrical stations is an easy and reliable solution. However, annual wind velocity on most settled territories does not exceed 6 m/s or even 4 m/s. It makes the efficient use of wind electrical stations more complicated. One of the solutions can probably be the use of wind and electrical stations on the basis of slow speed non-transmission arc-shaped-stator inductor-type generators with an integrated radial and ring-shaped rotor. Another efficient solution to provide areas with water and electrical energy is to use a combined wind station with a crank-and-rod mechanism and the rod of the driving mechanism of the back-and-forth motion of the core of a magnetic and electrical linear generator and the piston of a plunger pump.

Background

Considering economic feasibility and ecological safety, especially for the area remote from the centralized electrical networks and the systems of water supply, installations for providing consumers with electric energy and water must use as much as possible existing renewables.

Wind pump, wind electric pump and wind electrical units belong to such means of power supply and water supply. Wind pump installations are the simple and reliable decision but have low coefficient of loading of the wind turbine. For use of wind electric pump installations characteristic there is the general low efficiency. For electric pumps generally, it doesn't exceed 60%. Besides it is necessary to have a reserve of rated power if additional electroconsumers, except the electric pump are connected to wind electroinstallation.

One of the drawbacks of conventional non-transmission designs of a wind energy station is placing a continuous generating turbine with a large diameter on the horizontal axis, behind which (Sergeev, V.D., & Kuleshov, Е.V., & Proskurenko, S.S, & Chernyshova, А.S. (2000); RMA “Південне”. (1999)) an axial whirl is produced, and reverse air flows occur, thus, reducing significantly the kinetic wind energy caught with blades. Therefore, a conventional construction of a wind energy station has unacceptable limitations without a mechanical intensifier with a direct installation of a continuous housing of an electric generator on a horizontal axis. These are more unacceptable (Lebsir, A., Benbouzid, M.E.N., Bentonnsi, A., Salah, I.B. (2016)) for large-sized wind turbines.
