VERTICAL AXIS WIND TURBINE WITH ADJUSTABLE BLADES

V. M. Sineglazov, I. S. Shvaliuk

Abstract


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.
