摘要
A method and system for controlling a wind turbine generator detect wind speeds and, at a first defined wind speed, control generator torque and generator rotational speed to achieve a pre-defined power for the wind turbine generator at the first defined wind speed. As wind speed increases beyond the first defined wind speed, one of generator torque or generator rotational speed is increased and the other of generator rotational speed or generator torque is proportionally decreased to maintain the generator power substantially constant at the pre-defined power.
