SUBSTANTIATION OF MAGNETOELECTRIC VERTICAL-AXIAL GENERATOR FOR WIND TURBINE POWER SUPPLY OF ROAD INFRASTRUCTURE

Abstract

The article is devoted to research on the creation of electromagnetic systems of electricity generation using wind flows of road infrastructure. The aerodynamic model of the air flow of a moving vehicle is evaluated on the basis of known models made on the basis of the equations of aerodynamics. For the construction of the electromagnetic system of the electric generator of a vertical-axial wind turbine intended for the energy supply of road infrastructure, it is necessary to take into account special requirements for the efficiency of the use of multidirectional air flows from moving vehicles and wind activity from any direction. Experimental studies of the speed of wind flows generated by traffic on highways were conducted and confirmed the possibility of using their energy by wind turbines with a vertical axis. An analysis of scientific sources of generator development for compatible use with vertical-axis turbines was carried out. Several types of existing generators are considered and the structural similarity with the proposed prototype is described in detail, as well as a number of fundamental shortcomings.The result of the development was the creation of a system with increased vertical force of the magnetic suspension with its mechanical transmission to the wind turbine, minimizing the pulsations of the vertical forces of the magnetic suspension and reducing scattering fluxes and simplifying the manufacture and repair of windings.
