WIND GENERATOR CONTROL METHOD Russian patent published in 2022 - IPC F03D7/00 

FIELD: wind energy.

SUBSTANCE: invention relates to wind energy, in particular to wind turbines. The wind generator contains rotors with rotary single-leaf blades. The angle of inclination of the blades is set using fixed and movable guides, along which the blades slide. Movable guides are set to a predetermined position using a drive that operates depending on the load on the generator and on the wind speed. The wind generator can be equipped with controllable swivel canopies, which, as the wind intensifies, first direct the wind flow to the rotors, then reduce the wind flow to the rotors, and completely block it during a storm. In a wind generator rotor containing double-leaf blades, a given inclination of the wings is set using movable guides, along which the side edges of the wings slide. In the rotor, the inclination of the flaps of the blades can be set in the zone of opening of the flaps and in the zone of closing of the flaps. In these zones, the rotation of the flaps is released, set to a predetermined position using guides, blocked again, and then they move to the next zone for changing the position of the flaps. The efficiency of the wind generator is achieved through the use of controlled guides and visors. The protection of the rotor from the storm is carried out by pressing the guide blades of the rotor to the stops on the rotor and blocking the wind flow on the rotors with visors.

EFFECT: increasing the efficiency of the wind turbine and protecting it during a storm.
