Apparatus and method for controlling a variable speed wind turbine-generator at improved efficiencies is disclosed. The method and apparatus of the invention control the rotor tip speed below the limiting torque of the wind turbine at a selected constant velocity ratio with respect to wind speed and, above the limiting torque, control the rotor tip speed at speeds greater than those dictated by the constant velocity ratio up to a speed or power limit. This may be accomplished by controlling tip speed above the point where limiting torque is attainable to maintain optimal wind turbine performance along the performance envelope.
