Claims20
A method of controlling a wind turbine, the wind turbine comprising a plurality of blades, two or more of the plurality of blades comprising one or more light detection and ranging (LIDAR) systems for performing LIDAR measurements by transmitting light beams and detecting reflected light beams, wherein each of the LIDAR systems perform LIDAR measurements at different measurement points, the method comprising:
- a) obtaining LIDAR measurements from the one or more LIDAR systems whilst the blades rotate, in accordance with one or more measurement parameters;
- b) storing the LIDAR measurements, each LIDAR measurement being stored with associated measurement data, the measurement data corresponding to the one or more measurement parameters;
- c) determining a wind parameter based on the stored LIDAR measurements and associated measurement data, the wind parameter being indicative of a property of wind upstream of the wind turbine;
- d) determining a control parameter of the wind turbine based on the wind parameter;
- and
- e) controlling the wind turbine according to the control parameter.
A control system for a wind turbine, the wind turbine comprising a plurality of blades, two or more of the plurality of blades comprising one or more LIDAR systems for performing LIDAR measurements by transmitting light beams and detecting reflected light beams, wherein each of the LIDAR systems perform LIDAR measurements at different measurement points, the control system being configured to perform an operation, comprising:
- a) obtaining LIDAR measurements from the one or more LIDAR systems whilst the blades rotate, in accordance with one or more measurement parameters;
- b) storing the LIDAR measurements, each LIDAR measurement being stored with associated measurement data, the measurement data corresponding to the one or more measurement parameters;
- c) determining a wind parameter based on the stored LIDAR measurements and associated measurement data, the wind parameter being indicative of a property of wind upstream of the wind turbine;
- d) determining a control parameter of the wind turbine based on the wind parameter;
- and
- e) controlling the wind turbine according to the control parameter.
