Abstract: The invention relates to wind-power engineering and can be used for autonomous power supply of objects and for producing electric power in an electric power system. Said invention is aimed at increasing the wind power use factor in the process of time independently of the wind direction and speed, simplifying the structural design, improving operating features, reducing production and maintenance costs and increasing reliability, while increasing a unit power capacity thereof. The inventive wind power plant is characterized in that comprises a weight, brackets, blades embodied in form of two or more tube segments (a hollow cylinder). The brackets are rigidly fixed to bearings. The bearings are installed on a stationary axis, wherein the inner and outer edges of the blades at their faces are connected along a chord by means of a linkeach link is hinge-attached to the brackets between the center and the outer edge. Each blade at their faces between the center and the outer edge is hinge-connected by a link by means of a rod of an adjacent blade, wherein one end of the rod is hinge connected to the blade at their faces between the center and the outer edge, whilst the other end of the rod is hinge-connected to the link of the adjacent blade between the center and the outer edge of the blade. The link of a blade is hinge-connected to an L-shaped lever-bracket and weights are attached to the opposite end of the lever-bracket which is hinge-attached to a bracket. A drive gear is rigidly attached to a lower bracket, which is engaged with a smaller-diameter driven gear at the bottom, the smaller-diameter driven gear is engaged to a universal shaft or a ball socket. The universal shaft (and/or the ball socket) is connected at the bottom to an electromechanical unit. At the top, the stationary axle is attached to trusses or cables the bottom ends of which are tied to the ground or foundation. The trusses (or cables) are tied in the middle to the ground and/or to each other. According to another embodiment a wind-power plant comprises a weight, brackets, blades embodied in form of two or more tube segments (a hollow cylinder). The brackets are rigidly fixed to bearings. Two or more blades are hinge-connected to brackets at their faces between the center and the outer edge of each blade, wherein the inner and outer edges of each blade at their faces are connected along a chord by means of a link. The link of each blade is hinge-attached to a link of the adjacent blade by means of a rod, wherein one end of the rod is hinge-attached to a rod at the outer edge whilst the other end of the rod is hinge-connected to the link of the adjacent blade between the link center and the inner edge of the blade or with an adjacent blade between the center and the inner edge. The link of a blade is hinge-connected to an L-shaped lever-bracket and weights are attached to the opposite end of the lever-bracket which is hinge-attached to a bracket. A drive gear is rigidly attached to a lower bracket, which is engaged with a smaller-diameter driven gear at the bottom, the smaller-diameter driven gear is engaged to a universal shaft or a ball socket. The universal shaft (and/or the ball socket) is connected at the bottom to an electromechanical unit. At the top, the stationary axle is attached to trusses or cables the bottom ends of which are tied to the ground or foundation. The trusses (or cables) are tied in the middle to the ground and/or to each other.
