This article discusses a hardware and software complex for the study of aerodynamics and electromechanical characteristics of wind turbines (WPP) with a vertical axis of rotation. The created laboratory stand makes it possible to carry out experimental studies of the developed wind power plants, to obtain the dependences of the angular speed of rotation of the rotor and the consumed electric power on the wind speed. To demonstrate the efficiency of the considered vortex-type wind turbine, the corresponding prototypes of wind turbines with a power of 0.2 kW and 1.2 kW were designed and assembled, and their full-scale tests were carried out. The developed software makes it possible to carry out numerical simulation of the motion of a wind turbine with an unsteady undisturbed wind flow, taking into account the mass-inertial characteristics of the installation and the nature of the moment of resistance to the rotation of its rotor. Experimental and numerical results obtained using the developed hardware-software complex are presented and compared. These results indicate the possibility of using such a complex as an effective tool for the development of wind turbines with a vertical axis of rotation.

An idea is introduced of the directing structures of the director and reflex types that contribute to the formation of air flows, which in a given way contribute to an increase in mechanical power on the shaft of its rotor. These structures can be used to amplify the moment on the rotor shaft by increasing its useful interference with the stator. Qualitative considerations about the influence of the introduced guide structures are confirmed by the introduction and numerical aerodynamic calculations of two modernized designs of a promising vortex wind power installation, considered in the previous works of the authors. The most optimal variant of rotor modernization was selected, which made it possible to increase the power on its shaft by an average of 45% relative to the corresponding power for the design of a wind turbine with an initial rotor shape in the operating range of wind speeds from 1 to 12 m / s. The materials of this article can be used to design the optimum aerodynamic power criterion for the rotor of wind power plants, their stations, as well as integrated power power plants, including a wind power plant as one of the renewable sources of energy.
