METHOD FOR CONTROLLING A WINDMILL BY OPTIMIZING ITS PRODUCTION WHILE MINIMIZING THE MECHANICAL IMPACT ON TRANSMISSION

摘要

- Process to control a wind turbine by optimizing its production while minimizing the mechanical impact on the transmission. optimizing the production of electrical energy of a wind turbine, said wind turbine comprising a nacelle provided with a rotor on which blades are fixed, and an electric machine connected to said rotor by a transmission, in which an angle of inclination is controlled said blades, characterized in that it comprises the following steps: a) determining an aerodynamic torque setpoint and a torque setpoint of the electric machine making it possible to maximize the power recovered, from measurements of wind speed, speed rotor and speed of the electric machine; b) modifying at least one of said setpoints by subtracting from it a term proportional to a difference between the measured speed of the rotor and the measured speed of the electric machine; c) determining an angle of inclination of the blades to achieve said set of aerodynamic torque; d) the blades are oriented according to said angle of inclination.
