System and method for controlling speed and torque of a wind turbine beyond rated wind speed conditions

摘要

A method and system for controlling a wind turbine 10 generator 24 at wind speeds in excess of rated wind speed to detect wind speeds and, at rated wind speed, control generator torque and generator rotational speed to achieve a rated power for the wind turbine generator 24. As wind speed increases beyond the rated 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 24 power substantially constant at rated power.
