STRUCTURAL AND REGIME PARAMETERS OF A VERTICAL-AXIAL WIND TURBINE.

Abstract

Abstract. In this paper, the process of experimental studies to determine the design and operating parameters of a vertical wind turbine is considered in detail. The problem of power supply of electric vehicle charging stations based on alternative energy sources can be successfully solved through the use of vertical-axial rotary wind power plants (VO RVEU), which are environmentally safe and technically more versatile. At the same time, the mechanical energy of the rotating shaft can be used both to generate electricity and to drive working mechanisms directly, which reduces the number of required 8 batteries from 1.2 to 8 times. At the same time, the RVEU is launched at a low starting wind speed of 2.0 m/s and does not require orientation to the wind. Also, all the mechanisms of the installation are located at the bottom and are available for maintenance and repair in the conditions of farms.

Thus, a problem has formed, consisting in the need to develop the calculation of rotary vertical-axial wind turbines and the conditions for their use for power supply of electric vehicle charging stations based on alternative energy sources.

The article describes the process of conducting experimental studies to determine the optimal design and operating parameters of a vertical-axial wind turbine. The results of the experiment were processed using the MathCAD 14 program, the analysis of the search for the maximum and minimum values of the design-mode parameters of the wind turbine was made. The technical novelty of the developed wind turbine is protected by the patent of the Republic of Kazakhstan No. 36035 dated 30.10.2021.
