METHOD OF AND DEVICE TO CONTROL WIND POWER GENERATING PLANT Russian patent published in 2007 - IPC F03D7/04 

FIELD: wind power engineering.

SUBSTANCE: proposed method of control comes to aerodynamic limiting of powder developed by windwheel by changing position of its blades relative to wind and stopping of windwheel by reducing power on windwheel to its nominal value. Power on windwheel is reduced by adjusting difference in rotating torques on shaft of windwheel and output shaft by building constant torque on output shaft and control of torque on windwheel shaft by self-adjusting devices, for instance, elastic members. Wind power generating plant contains windwheel and hub made in form of cylindrical cup with slots to receive bushing with rods, rotary blades being secured from outer side and gears in meshing with gear secured on bushing freely fitted on windwheel shaft, on outer side. Bushing is provided with gear with slots from opposite end into which fork is fitted rigidly coupled with shaft of windwheel, and elastic members are arranged between fork and wall of slot. Gear with slots is in meshing with gear installed on output shaft from opposite side of which power takeoff device is secured.

EFFECT: prevention of destruction of wind power generating plants at storm winds.
