WIND-DRIVEN POWER PLANT Russian patent published in 2015 - IPC F03D9/02 

FIELD: power industry.

SUBSTANCE: wind-driven power plant includes blades on a shaft with an attachment assembly to an operating machine, an electric drive with variable rotation frequency, an electrical generator, a freewheel clutch, a controller and a speed sensor of blades. The attachment assembly of the shaft of blades to the operating machine is made in the form of a mechanical connection automatically controlled with a controller. The electric drive is made as a starting motor provided with a speed sensor and connected through the freewheel clutch to the shaft of the operating machine. The controller provides for actuation and synchronisation of speed of the starting motor with speed of blades upon achievement of an empirically set value in a pulse operating mode of the plant, and the electrical generator is constantly connected to the shaft of blades.

EFFECT: improvement of operating efficiency of wind-driven power plants under conditions of unstable wind flows; partial or complete refusal to use environmentally hazardous and expensive storage batteries; reduction of prime cost of the generated energy.
