摘要： A method of real-time monitoring of the operation of a wind turbine in an operational region of theoretically constant power coefficient is disclosed. The method comprises measuring the electrical power generated by the wind turbine, a representative wind speed, and an ambient temperature. The wind power available to the wind turbine for a given moment in time may be calculated based on the measured ambient temperature and measured representative wind speed. The aerodynamic power captured by the wind turbine at the same moment in time may be determined based on the measured electrical power generated. And the practical power coefficient may be calculated by dividing the aerodynamic power captured by the calculated available wind power.
