WIND-DRIVEN PLANT WITH BLADE CONTROL UNIT Russian patent published in 2012 - IPC F03D3/00 

FIELD: power engineering.

SUBSTANCE: wind-driven plant comprises a generator, having a vertical axis of rotation, cross beams, rotary blades, a mast and a plant control unit. Rotary blades are arranged in the form of upper and lower half-blades and are joined to each other by means of a shaft, the axis of rotation of which is parallel to the vertical axis of rotation of the plant generator. The blade control unit comprises electric motors joined via reduction gears with kinematic units of rotation of half-blade shaft, which are arranged in the form of body elements installed at the ends of cross beams. In the inner cavity of body elements there are shafts of half-blades installed with the help of bearings, with a reduction gear installed on each one. Electric motors in their turn are installed on the side external part of the body elements of kinematic units. Electric motors are supplied via a current collector installed on the upper shield of the generator. The blade control unit is connected to the unit of plant control, which after processing of information about plant rotations, speed and direction of wind in this period of time, generates a signal of an optimum angular position of blades relative to wind direction.

EFFECT: increased efficiency of a plant.
