Abstract
A method and system for improving power production efficiency on a wind farm having of a plurality of spatially distributed wind turbines is provided. The method includes receiving a wind measurement that includes a wind direction impinging on a turbine (20), determining a misalignment of the wind turbine with respect to the wind direction, and activating a wake steering control for the wind turbine (20) to implement the misalignment of the wind turbine (20) with the wind direction such that the misalignment is adapted to steer a wake of the wind turbine away from a neighboring wind turbine (30). A wind turbine arrangement including a nacelle, a yaw controller, and a yaw drive is also provided.
Claims20
A method implemented on a wind farm having a plurality of spatially distributed wind turbines for improving power production efficiency, comprising:
- receiving a wind measurement comprising a wind direction impinging on a turbine;
- determining by a processor a misalignment of the wind turbine with respect to the wind direction, wherein the misalignment is adapted to steer a wake of the wind turbine away from a neighboring wind turbine;
- and
- activating a wake steering control for the wind turbine by producing a control signal adapted to implement the misalignment of the wind turbine with the wind direction.
A system for improving power production efficiency on a wind farm having a plurality of spatially distributed wind turbines, comprising:
- a data processing device for receiving a wind measurement comprising a wind direction impinging on a turbine;
- determining a misalignment of the wind turbine with respect to the wind direction, wherein the misalignment is adapted to steer a wake of the wind turbine away from a neighboring wind turbine;
- and activating a wake steering control for the wind turbine by producing a control signal adapted to implement the misalignment of the wind turbine with the wind direction.
A non-transitory computer readable medium containing instructions that when executed by a processor perform acts comprising:
- receiving a wind measurement comprising a wind direction impinging on a turbine;
- determining a misalignment of the wind turbine with respect to the wind direction, wherein the misalignment is adapted to steer a wake of the wind turbine away from a neighboring wind turbine;
- and
- activating a wake steering control for the wind turbine by producing a control signal adapted to implement the misalignment of the wind turbine with the wind direction.
