Abstract
The provision of electricity to remote agro-industrial complexes (AIC), industrial enterprises and small settlements is associated with problems of fuel delivery or the installation of extended transmission lines, which requires additional financing. In the proposed article, wind power installations with a vertical axis of rotation of a wind turbine with blades using the principle of differential drag are proposed, which will be able to solve the situation. To ensure the efficient operation of these wind turbines, it is proposed to increase the air flow velocity in the volume of the wind turbine and prevent the wind turbine from flowing around the air flow. To do this, a technique is proposed to determine the optimal size of the blades and their number for a more complete use of the energy of the airflow. The analysis of the operation of the wind turbine shows that in order to increase the efficiency of its operation in the conditions of the wind regime of Russia (from 3 to 5 m/s), it is necessary to increase the speed of the air flow in the volume of the wind turbine, to ensure the passage of the air flow through its volume preventing its flow, to improve the aerodynamic coefficients of the blades. It should be taken into account, increasing the speed of the air flow in the volume of the wind turbine, it is necessary to determine the number and size of the blades, taking into account their location, otherwise the wind turbine will flow around.
