Abstract
Embodiments of the invention provide methods, systems, and apparatus for determining a property of wind approaching a wind turbine. A light detection and ranging equipment may be used to determine a property of the wind at a plurality of locations ahead of a turbine. A wind flow model may be used to determine the property of wind expected at the rotor of the wind turbine based on the readings of the light detection and ranging device.
Claims12
A method for determining a property of wind approaching at least one wind turbine, comprising:
- retrieving a plurality of sensor measurements from one or more sensor devices, wherein each sensor device is configured to measure the property of the wind at a plurality of locations;
- determining a property of the wind expected at a rotor of the wind turbine based on the plurality of sensor measurements and a predefined model of wind flow;
- and
- adjusting at least one operational parameter of the wind turbine based on the property of wind expected at the rotor of the wind turbine.
A wind turbine comprising a processor configured to:
- retrieve a plurality of sensor measurements from one or more sensor devices, wherein each sensor device is configured to measure the property of the wind at a plurality of locations;
- determine a property of the wind expected at a rotor of the wind turbine based on the plurality of sensor measurements and a predefined model of wind flow;
- and
- adjust at least one operational parameter of the wind turbine based on the property of wind expected at the rotor of the wind turbine.
A wind power plant comprising;
- a plurality of wind turbines;
- one or more wind sensing devices;
- and
- a power plant processor configured to:
- retrieve a plurality of sensor measurements from the one or more sensor devices, wherein each sensor device is configured to measure the property of the wind at one or more locations;
- determine a property of the wind expected at a rotor of at least one of the plurality of wind turbine based on the plurality of sensor measurements and a predefined model of wind flow;
- and
- adjust at least one operational parameter of the at least one of the plurality of wind turbines based on the property of wind expected at the rotor of the wind turbine.
