    摘要: A wind turbine (30) comprising: a rotor (36) having a plurality of blades (38); and a controller (100). The controller (100) is arranged to independently control each of the plurality of blades (38) and/or one or more components of each blade (38) in order to increase a driving moment of each blade (38) independently of other of the blades (38) when speed of wind acting on the wind turbine (30) is below rated. The controller (100) is also additionally or alternatively arranged to independently control each of the plurality of blades (38) and/or one or more components of each blade (38) independently of other of the blades (38) when wind force acting on the blades (38) is above cut-out in order to reduce a mechanical load experienced by at least a part of the wind turbine (30).

    摘要: A LIDAR or other remote sensing apparatus is mounted on a wind turbine to sense one or more wind parameters. An extreme event detector processing signals from the LIDAR to determine whether a given sensed parameter will, when it arrives at the turbine, exceed a predetermined value and represent an extreme event. On detection of an extreme event, the detector outputs an extreme event signal to a controller. The controller controls overrating of the turbine in response to a variety of sensed parameters and selectively operates the turbine at above rated wind speed. On receipt of the extreme event signal the overrating is overridden to prevent damage to turbine components. The controller may be a power plant controller and the override signal may override only over-rating at the turbine which has detected the extreme event, or a plurality of turbines.

    摘要: A wind turbine variable is controlled by detecting air flow conditions in front of the leading edge of the blade. One or more Laser Doppler Anemometers are mounted on or incorporated into the blade to determine air flow velocity in the region in front of the leading edge of the blade. The measured flow conditions may be used to control the position of a control surface such as a trailing edge flap or the rotor speed. The LDAs may comprise lasers of different frequencies to enable more than one component of flow velocity to be measured.
