WIND-DRIVEN POWER PLANT WITH TWO WINDWHEELS Russian patent published in 2020 - IPC F03D7/02 F03D15/00 

FIELD: power engineering.

SUBSTANCE: invention relates to wind-power engineering and can be used in control of wind-driven power plant (WDPP) with two windwheels. Wind-driven power plant with two windwheels comprises blades of windwheels, hubs and common shaft of windwheels, electric generator, power system. Shaft of windwheel is connected to shaft of electric generator, stator winding of which is connected to power system. Located on common shaft of windwheels unit to control angle between windwheels with electric motor and system of transmission "screw-nut", hub of the second windwheel and the common shaft are made with possibility of mutual rotation and are equipped with posts rigidly fixed on them and connected to each other by an electric motor with a "screw-nut" transfer system. Motor stator is articulated with one of the posts; the rotor of the electric motor is made hollow in the form of a nut of the "screw-nut" transmission system, the screw of which is hingedly connected to the second post.

EFFECT: invention ensures efficiency of using installed capacity of wind-driven power plant and, accordingly, increased output of electric energy by increasing use of wind energy with reduction of its speed with simultaneous simplification of device by excluding splined transmissions.
