WIND POWER PLANT Russian patent published in 2021 - IPC F03D7/02 F03D1/00 

FIELD: wind energy.

SUBSTANCE: invention can be used to generate electricity in conditions of pulsations of wind speed. The wind power plant contains a wind wheel, a support tower, a nacelle with an electric unit, a rotary base equipped with a device for orienting to the wind flow, made in the form of a two-keel circuit shank. Contains a hurricane protection system, including a mechanical threshold relay and a shock absorber, made in the form of a tail with a plumage - two blades oriented at an angle of 90 degrees to each other; while one of the blades is fixed motionless, and the second has the ability to move after the threshold device is triggered when the wind speed reaches a storm value; in addition, the shock absorber is configured to ensure smooth movement of the movable blade due to the possibility of choosing the value of the shock absorber damping.

EFFECT: technical result is to increase the service life of wind turbines, which allows them to be serviced much less often.
