Abstract: The invention relates to wind power engineering and can be used for autonomous power supply of objects and generation of power to a power grid. The technical result is aimed at enhancement wind power efficiency independently of wind direction and velocity, simplification of design and improving operation features, reduction costs of construction thereof and operation charges, increasing reliability with simultaneous increase of unit capacity of a wind power plant. The invention is characterized in that the wind power plant comprises brackets, a bearing unit with a housing, drive and driven gears, rods, levers with a post, Γ-shaped lever with a weight, blades embodied in the form of two or more segments of the external part of a hollow torus provided with top and low edges as well as internal and external end faces. The external part of a hollow torus represents an outer semicircle in a cross section which provides to imagine it in a cross section as a part of an automobile tire of simpler shape (in the form of semicircle).The brackets are rigidly attached to the bearing housing, the bearings are installed on a stationary axle. Each blade is hingedly fastened to brackets from outside between the internal and external end faces. Rods are pivotally connected to the blade between a center and the external end face near the top and low edges and are hingedly fastened, by the other end, to the adjacent blade from outside by means of levers provided with a post, the posts are rigidly attached to the blade. One of the blades is hinge-connected to an Γ-shaped lever-bracket, at the other end of which a weight is arranged, the lever-bracket with the weight is hingedly attached to the bearing housing, the drive gear is engaged with a smaller-diameter driven gear, which is rigidly attached with a universal shaft or a shaft with a ball socket. The stationary axle is installed inside the drive gear, the universal shaft (or a shaft with a ball socket) is connected at the bottom to an electromechanical unit, and the stationary axle is rigidly attached to a support. According to another embodiment a wind power plant comprises brackets, a bearing unit with a housing, drive and driven gears, rods, Γ-shaped levers with a posts, Γ-shaped lever with a weight, blades embodied in the form of two or more segments of the external part of a hollow torus provided with top and low edges as well as internal and external end faces. The brackets are rigidly attached to the bearing housing, the bearings are installed on a stationary axle. Each blade is hingedly fastened to brackets from outside between the internal and external end faces by means of the Γ-shaped levers with posts. Rods are pivotally connected to the blade, the bracket is hingedly attached to the Γ-shaped levers with a posts in the center. The ends of the Γ-shaped levers with a posts are hingedly connected with rods. One of the blades is hinge-connected to an Γ-shaped lever-bracket, at the other end of which a weight is arranged, the lever-bracket with the weight is hingedly attached to the bearing housing, the drive gear is rigidly connected to the bracket housing beneath thereof, which, via the smaller-diameter driven gear, is rigidly attached with a universal shaft or a shaft with a ball socket. The stationary axle is installed inside the drive gear, the universal shaft (or a shaft with a ball socket) is connected at the bottom to an electromechanical unit, and the stationary axle is rigidly attached to a support.
