METHOD TO CONTROL ANGULAR SPEED OF WIND TURBINE ROTATION WITH VERTICAL AXIS Russian patent published in 2014 - IPC F03D3/04 

FIELD: power engineering.

SUBSTANCE: method to control angular speed of rotation of a wind turbine with a vertical axis, in which blades of the wind turbine during change of which are radially moved, varying distance between the blade and the axis of wind turbine rotation, during hurricanes they forcedly move the blades closer to the axis of rotation of the wind turbine. In the lower part of the wind turbine they install weights in the form of reservoirs of aerodynamic airfoil with the common centre of gravity at the axis of rotation of the wind turbine, which are filled by liquid or drained and synchronously forcedly moved along horizontal radially arranged guides, varying distance between the axis of rotation of the wind turbine and the centre of gravity of each weight.

EFFECT: invention makes it possible to increase efficiency of control of angular speed of wind turbine rotation with simultaneous control and stabilisation of wind turbine capacity.
