WIND-POWER STATION OF HIGH POWER EFFICIENCY Russian patent published in 2014 - IPC F03D3/02 F03D3/04 

FIELD: energy industry.

SUBSTANCE: invention relates to wind energy and can be used to create wind power stations of high power efficiency. The wind power station comprising a module contains a vertical axis with blades, mounted in bearing assemblies, upper and lower, a platform mounted on supports, on the platform the lower bearing assembly of the vertical axis is mounted, an arc screen is placed covering the part of the blades from the wind, having at least one support wheel communicated with the transmission to the motor, axisymmetric surface interacting with the wheel. The arc screen is equipped with automatic system of the angular orientation by the signals of the sensor of wind parameters. The vertical axis of the module is kinematically connected to the shaft of the electric generator. On the supports the second platform of the module is fixed, on which the upper bearing assembly of the vertical axis is mounted and axisymmetric surface interacting with at least one support wheel of the screen, providing an angular displacement of the arc screen from the motor. On the upper platform the additional modules are secured on the supports in tiers, and the upper platform of the downstream module is a lower platform of the module, and the vertical axes of the modules are kinematically connected.

EFFECT: invention provides improvement the power efficiency in operation in automatic mode with high operation factor of wind energy.
