Abstract: The invention relates to a method of controlling a wind turbine comprising at least one wind speed sensor, a number of pitch-adjustable rotor blades, and a control system for changing the pitch of the rotor blades and/or a generator torque. The method comprises firstly determining at time intervals an error parameter as the difference between an estimated wind speed and a measured wind speed as measured by the wind speed sensor. Then, based on a number of pre-defined wind speed intervals, it is for each wind speed interval obtained a group of error parameters over time. For each wind speed interval and for each group of error parameters is determined a wind speed offset based on the average of the error parameters within the group which wind speed offsets are used in adjusting the measured wind speed. Hereby a more precise wind speed measurement is obtained which can be used in the controlling of the turbine. The invention further relates to a control system for a wind turbine for performing a control method as mentioned above.

Abstract: The invention relates to a method of controlling a wind turbine comprising a wind direction sensor, a yawing system, and a control system for yawing the wind turbine rotor relative to the wind. The method comprises measuring a first wind direction parameter by the wind direction sensor before performing a yaw event. The yaw event comprises the steps of determining a yawing parameter for the wind turbine as a function of the wind direction parameter, and yawing the wind turbine according to the yawing parameter. Then a data set is determined which data set comprises the first wind direction parameter, a wind direction sensor angle determined as a difference in the measured wind direction parameter before and after the yawing event, and a yaw angle indicative of the yawing performed during the yawing event. Over time a group of data sets is obtained and a wind direction offset is determined from the group of data sets which is used to adjust the wind direction parameter. The adjusted wind direction parameter is then used in the controlling of the wind turbine. The invention further relates to a control system for a wind turbine for performing a control method as mentioned above.

Abstract: The invention relates to a method of controlling a wind turbine comprising a wind direction sensor, a number of pitch-adjustable rotor blades, a yawing system, and a control system for yawing the wind turbine rotor relative to the wind and for changing the pitch of the rotor blades. The method comprises measuring a wind direction parameter by the wind direction sensor, wherein the wind direction parameter is indicative of the wind direction relative to the wind turbine. Then firstly the measured relative wind direction is calibrated as a function of a predetermined offset parameter, and secondly the calibrated relative wind direction is adjusted as a function of a wind direction compensation parameter, wherein the wind direction compensation parameter depends on the calibrated relative wind direction. The adjusted relative wind direction is then used in the determining of a control parameter of the wind turbine. The parameters for the calibration and adjustment of the relative wind direction are obtained from a set of data comprising the wind direction relative to the wind turbine over time and as measured by the wind direction sensor on the wind turbine and as measured by a second wind direction sensor. The invention further relates to a control system for a wind turbine for performing a control method as mentioned above.
