WIND POWER PLANT

摘要

The wind power plant comprises at least one wind generator, consisting of blades that extract wind energy and at least one electromechanical converter that is connected to said blades. The wind generator blades are secured in such a way that they are capable of performing flexural vibrations transverse to the flow and torsional vibrations along their own elastic axis (flutter). The wind generator is positioned in the meshes of a net in such a way as to be capable of rotating 180º about a vertical axis under the action of the wind, for which purpose the blades are situated behind the axis of rotation. With the aid of frames and guys, nets are hung in several rows with a certain distance therebetween. Each wind generator is provided with a hub that is connected to a horizontal torsion bar and has blades mounted therein in such a way that the blades are able to rotate about their own axes. Each blade is provided with a torsion bar, the axis of which coincides with the longitudinal axis of the blade and which joins the blade and the hub, and the centre of mass of each blade is offset backwards in the direction of flow of the wind relative to the axis of the blade. The invention provides for an increase in the range of working velocities of the flow.
