Abstract: A variable speed wind turbine includes a frequency converter which converts variable frequency AC from a turbine driven AC generator to fixed frequency AC for delivery to a power grid. The frequency converter is typically an electronic cycloconverter or rectifier-inverter and is also used to control the power flow from the AC generator to the grid which thereby controls the air gap torque between the generator stator and rotor. The turbine speed is maneuvered to increase efficiency by precisely controlling the air gap torque according to a schedule defining sensed generator speed versus sensed generated power.

Abstract: 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.
