摘要： If blades have been struck by wind that has reached a power reduction start wind speed that is lower than a conventional cut-out wind speed at which torque acting on a main shaft reaches the torque limit, a wind turbine generator performs torque reduction control for causing the change in the torque when wind speed is higher than the power reduction start wind speed to be different from change in the torque when wind speed is lower than the power reduction start wind speed so as to prevent the torque from exceeding the torque limit at the conventional cut-out wind speed. For example, if the wind striking the blades reaches the power reduction start wind speed, the wind turbine generator sets the slope of change in torque lower than that before the power reduction start wind speed is reached. Accordingly, the wind turbine generator can reduce the load acting on a device and suppress a reduction in power even if the blades are struck by strong wind.

摘要： A controller and method is disclosed for operating a variable speed turbine to better track wind speed fluctuations for greater efficiency in conversion of wind energy to electrical energy. The controller of the invention controls the rotor speed in accordance with a wind speed supplied by a wind observer in order to approximately follow the varying wind speeds. The wind observer predicts the average wind speed at a subsequent point in time over the cross-section presented to the wind by the wind turbine. The average wind speed is applied to a parameter schedule to determine desired values for rotor speed and torque which are used by arotor speed stabilizer to command a reference load torque. The load torque of the generator is controlled in accordance with the commanded load torque, and therefore the desired rotor speed is approximated. During operation, the wind speed prediction process is repeated at each subsequent time interval, and the load torque, and therefore rotor speed, is controlled accordingly. The wind observer calculates the aerodynamic torque and then calculates net torque. The wind speed is predicted as a function of the present (previously predicted) wind speed and correction terms including net torque and the difference between the predicted and actual rotor speed. The wind observer is useful whenever the wind turbine rotor is turning, whether or not it is producing power.
