WIND-DRIVEN PLANT Russian patent published in 2014 - IPC F03D3/00 

FIELD: power industry.

SUBSTANCE: invention relates to wind power engineering. A wind-driven plant includes an air intake with a windwheel with blades, which is located inside it; the above blades are attached to upper and lower rings supported from centring rollers installed on shafts of rotors of energy converters, and flow rarefaction devices that are located from above and from below. Flow rarefaction devices are installed so that they can be rotated relative to the air intake and the windwheel to transfer torque moment to an energy convertor stator. On the inner side of flow rarefaction devices there installed are blades with an aerodynamic profile providing opposite rotation of flow rarefaction devices in relation to the windwheel.

EFFECT: invention improves operating efficiency of a wind-driven plant.
