Claim Text:
1. A method of real-time operational control of a wind turbine within an operational region of theoretically constant power coefficient, the wind turbine having a rotor with a plurality of rotor blades and a generator, the method comprising: measuring electrical power generated by the wind turbine, a representative wind speed, and an ambient temperature; calculating wind power available to the wind turbine at a moment in time based on the measured ambient temperature and the measured representative wind speed; determining aerodynamic power captured by the wind turbine at substantially the same moment in time based on the measured electrical power generated; and calculating a practical power coefficient by dividing the aerodynamic power captured by the calculated available wind power, and collecting the practical power coefficient over an operational region of theoretically constant power coefficient, and providing the collected practical power coefficient to a wind turbine control system, and using the wind turbine control system, making an operational change based on the collected practical power coefficient.
