(«Освіта України», 2017-09) Sineglazov, V. M.; Shvaliuk, I. S.
The goal of this paper is to increase the efficiency of using alternative energy sources, namely: to analyze the ways of controlling the angular position of the wind turbine blade. The object of analysis are the wind turbines with a vertical axis of rotation, the subject of analysis is justification for the use of adjustable blades in a vertical-axis rotor. Critical analysis of various methods blade angle control of the wind turbine has been carried out and task of active and passive control systems design for the vertical-axis wind turbine rotor blade angular position has been solved.

Carried out analysis of existed vertical axis wind turbines. Considered the combination of Savonius and Darrieus type vertical axis wind turbine with adjustable blade applying.
INVESTIGATION OF BLADE ATTACK ANGLE VALUE ON VERTICAL AXIAL WIND POWER PLANT
(Київ «Освіта України», 2018-06) Sineglazov, V. M.; Shvaliuk, I. S.
In this paper, the efficiency of the vertical-axial wind power plant at various wind speeds depending on the angle of attack of the rotor blades was investigated. The object of the investigation was a three-bladed Darrieus rotor. During the modeling we used the viscous gas flow model with averaging of turbulent characteristics (Reynolds-averaged Navier–Stokes equations for an incompressible fluid. These investigations would allow us to develop new principles for constructing vertical-axial wind turbines with a variable angle of attack of the blades in order to increase the energy efficiency of vertical-axis wind turbine.
VERTICAL AXIS WIND TURBINE WITH ADJUSTABLE BLADES
(Київ «Освіта України», 2018-12) Sineglazov, V. M.; Shvaliuk, I. S.
It is researched the problem of energetic efficiency increasing of wind energy plant with vertical axis of rotation. For the solution of this problem it is proposed to use the adjustable blades. It is determined the optimal angle of attack of different wind velocities as a result of Navier–Stokes equations solution under different initial conditions (different values of attack angles and wind velocities). It is proposed the approach for the realization of control system of blade angle rotation based on PID-Controller. It is developed the algorism of adaptive PID-Controller. It is developed a Simulink model for this control system.
