Abstract: A yaw sensor for a wind turbine is described. The yaw sensor comprises a rotary switch, configured to be coupled to a yaw drive gearbox of a wind turbine nacelle, the rotary switch being operable to activate and deactivate an electrical contact in dependence on an amount of yaw rotation of the nacelle relative to a start position. The electrical contact is active at a plurality of first yaw rotation ranges with respect to the start position, and inactive at a plurality of second yaw rotation ranges with respect to the start position, the first and second yaw rotation ranges being interleaved, at least some of the first yaw rotation ranges having different lengths from each other and/or at least some of the second yaw rotation ranges having different lengths from each other. The electrical contact generates an electrical signal when active.

Abstract: Method of controlling a wind turbine. A data set is obtained that includes a direction of the wind relative to the wind turbine and a pitch angle parameter representing a pitch angle of at least one of the wind turbine blades. Based on the obtained data sets, a statistical representation of the pitch angle parameter as a function of the relative wind direction is determined, which is then used in estimating a wind direction offset corresponding to the relative wind direction where the pitch angle parameter attains a maximum. The relative wind direction of the wind turbine is then adjusted as a function of the wind direction offset.

Abstract: A method for operating a cluster (1) of a plurality of wind turbines (2) is disclosed. For each of the wind turbines (2), one or more parameter values of a parameter being indicative for a condition occurring at the wind turbine (2) are derived, based the measurements obtained by the wind turbine (2). In the case that a derived parameter value for a specific wind turbine (2) exceeds a trigger value, measures for mitigating an effect of the condition at the specific wind turbine (2) are initiated. The derived parameter values for the wind turbines (2) of the cluster (1) of wind turbines (2) are compared to an expected distribution (9) of the parameter values. In the case that a distribution of the derived parameter values differs from the expected distribution (9) of the parameter values, the trigger value is adjusted, and the adjusted trigger value is subsequently applied when comparing the derived parameter values to the trigger value.

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 obtaining an estimate for a wind power parameter as a function of a relative wind direction, where the wind power parameter is determined as one of a power, a torque, a blade load, or a blade pitch angle of the wind turbine. At time intervals, a data set is established comprising a wind power parameter and a wind direction parameter as measured by the wind direction sensor. Over time a group of data sets is then obtained for a number of pre-defined wind direction intervals, and a wind direction offset is determined for each interval by comparing the average wind power parameter for that interval with the estimate of the wind power parameter. The wind direction offsets of the different wind direction intervals are used to adjust the wind direction parameter, and applied 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.
