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 controlling a wind turbine system including an electrical generator, a power converter system, a DC-link, and at least a grid-side breaker arrangement controllable between open and closed states, wherein the method comprises monitoring for the presence of a shutdown event and, in response to identifying the presence of a shutdown event, controlling the wind turbine into a production-ready state, comprising: i) controlling the grid-side breaker arrangement in the closed state; ii) disabling one or more drive signals to the power converter system; and iii) controlling the DC-link of the power converter system in a charged state. Advantageously, this approach reduces the frequency of use of the grid-side breaker arrangement which extends serviceable life considerably, and also allows the wind turbine system to be transitioned rapidly between an operating state and a production-ready state.

Abstract: A method of controlling a floating-body wind turbine power generating apparatus including a wind turbine generator disposed on a floating body includes a pitch-angle increasing step of increasing a pitch angle of a blade of the wind turbine generator when the wind turbine generator is stopped, so that an aerodynamic braking force is applied to a rotor of the wind turbine generator. In the pitch-angle increasing step, a first change rate of the pitch angle of the blade in a first period during which the wind turbine generator is in an inclining motion toward an upwind side from a vertical direction due to sway of the floating body, is smaller than a second change rate of the pitch angle of the blade in a second period during which the wind turbine generator is in an inclining motion toward a downwind side from the vertical direction due to the sway of the floating body.

Abstract: A method for graphically presenting sensor data from wind power installations is provided. A data interface of an apparatus receives sensor data from wind power installations and/or wind farms connected to the data interface. A memory stores the received sensor data. An input interface is used to select at least one current time or part time. Furthermore, a display interface is used to output signals for the purpose of presenting geographical maps and sensor values using a display. A plurality of sensor data or all sensor data for the selected time are retrieved from the memory, and the display interface outputs display signals to present the retrieved sensor signals with a map substantially at a position at which the wind power installation from which the respective sensor data were received is positioned. An apparatus for carrying out the method and a system having the apparatus are provided.

Abstract: Groups of wind turbines at a wind farm are controlled based on detection of volant animal swarms. A risk score is defined for each of a plurality of wind turbine groups of the wind farm at a default risk score based on predetermined data. A respective operational parameter is set for each wind turbine of each of the wind turbine groups based on the respective risk score. The presence of a volant animal swarm is detected in a region associated with a given one of the wind turbine groups via a volant animal detection system. The risk score of the given one wind turbine group and an adjacent wind turbine group is changed from the default risk score to temporary risk scores in response to detection of the volant animal swarm.
