ABSTRACT:
Automatic torque control of wind energy conversion devices is provided through the utilization of turbine reaction torque. In the preferred embodiment, the frame of the driven machine is arranged to be rotatable through a limited angle. As rated torque of the system is exceeded, a force proportional to the turbine reaction torque is exerted by said frame to adjust the turbine aerodynamic configuration in such a manner as to reduce the torque error to substantially zero.
