Abstract
A wind turbine has a rotor with a hub that houses a remote sensing device such as a Lidar for each blade. Each Lidar has one or more look directions that extend generally radially along the respective blade in front of the blade. The Lidar has multiple range gates and wind parameters sensed at each range may be used to control surfaces on the blade such as a trailing edge flap.
Claims25
A control system for a wind turbine, the wind turbine having a rotor carrying blades, comprising a remote sensing device mounted for rotation with the rotor to sense at least one wind parameter in a look direction substantially parallel to and adjacent a bade, and a controller for generating a control signal to vary a parameter of the wind turbine in response to the sensed wind parameter.

A method of controlling a wind turbine, the wind turbine having a rotor carrying blades, comprising:
- sensing with a remote sensing device mounted for rotation with the rotor, at least one wind parameter in a look direction substantially parallel to and adjacent a blade, and
- controlling a parameter of the wind turbine with a control signal generated in response to the sensed wind parameter.
A windturbine comprising at least one lidar means for determining windspeed, wherein said at least one lidar means is mounted in a hub bearing blades of the turbine, such that as the hub rotates the at least one lidar means scans the area in front of the turbine wherein the at least one lidar means is mounted in the hub so as to have a look direction that radially extends away from the hub, and that is substantially parallel to and next to one of the blades extending radially from the hub.
