WIND-DRIVEN TURBINE POWER PLANT Russian patent published in 2020 - IPC F03D3/04 

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering, particularly, to designs of wind-driven power plants. Wind-driven turbine plant includes units 1 of wind turbine installed on vertical axis, between which electric generator 3 is mounted. Each of units 1 of wind turbines includes fixed stator 4 with concave-convex plates 17 and rotating rotor 5 with convex-concave blades 10 installed with possibility of opposite rotation relative to adjacent units 1 of wind turbine. Rotor and stator of electric generator 6 are mechanically connected with rotors 5 of units 1. Rotor 5 of each unit 1 of wind turbine is made in the form of rigid spatial structure, which additionally includes end wind wheels 8 with concave-convex blades 9, uniformly located along perimeter of wind wheels 9. Helicoid 12 is fixed between end wind wheels 8 and fixed on shaft 11 and made in the form of screw wing. End wind wheels 8 of rotors 5 are inextricably connected to each other by convex-concave blades 10 uniformly distributed along their perimeter. Convex-concave blades 9 of end wind wheels 8, helical wings of helicoids 12 of rotors 5 and concave-convex plates 17 of stators 4 are mounted so that to provide for opposite rotation of rotors 5 of adjacent blocks 1 of wind turbines. At end faces of wind-driven turbine plant there are conical air ducts 13 and 14 mounted smoothly changing into cylindrical pipes 15 and 16.

EFFECT: higher efficiency of wind energy use due to increased sweeping area of working surfaces of rotors and stator and relative speed of rotation of stator and rotor of electric generator.
