Abstract: Controlling a wind turbine comprising a wind sensor, a number of pitch-adjustable rotor blades, a yawing system, and a control system for yawing the wind turbine rotor relative to the wind and for changing the pitch of the rotor blades. A wind parameter is measured by the wind sensor, and is indicative of the wind speed and/or the wind direction relative to the wind turbine. At least a first and a second set of wind correction parameters for different production modes of the wind turbine are obtained. The production mode of the wind turbine is then determined, which may be one of at least normal operation or non-production, and the measured wind parameter is then adjusted as a function of the set of wind correction parameters corresponding to the production mode at the time of adjusting. Hereby a more precise wind parameter is obtained which can be used in the controlling of the turbine.

Abstract: The application relates to an apparatus (100) for fatigue testing a wind turbine blade specimen (10), and to a method using such an apparatus (100). The apparatus (100) comprises first and second support assemblies (120, 130) and an actuator (140) for cyclically deflecting the specimen (10) in a first transverse direction. The first and second support assemblies (120, 130) comprise first and second holders (121, 131) for holding first and second ends (12, 14) of the specimen (10), respectively, such that the longitudinal direction (16) of the specimen (10) extends between the first and second holders (121, 131). The first and second support assemblies (120, 130) are arranged such that the first and second holders (121, 131) are rotatable about a second transverse direction perpendicular to the first transverse direction and to the longitudinal direction (16) of the specimen (10). The first support assembly (120) is further arranged such that the first holder (121) is moveable in the longitudinal direction relative to the second holder (131) when the specimen (10) is deflected by the actuator (140) in the first transverse direction.

Abstract: A control system, for controlling a flow of wind through a wind power plant comprising a plurality of wind turbine generators, comprising: a first controller, local to the wind power plant, configured to: receive operational data relating to the wind power plant and, in 5response, to send control signals to the plurality of wind turbine generators based on an implemented wind power plant control function, and a second controller. The second controller is configured to: receive operational data from the wind power plant; train a wind power plant model using the received operational data; generate a trained wind power plant control function based on the trained wind power plant model; and transmit the 10trained wind power plant control function to the first controller. Following the transmission of the trained wind power plant control function to the first controller, the first controller is further configured to: update the wind power plant control function with the trained wind power plant control function. The invention has particular utility in the context of controlling the flow of wind through the wind power plant, for example by controlling the wake steering 15and/or axial induction factor of the wind turbines in the power plant. A complex dynamic relationship exists between the control actions of wind turbines and the resultant wind flow through the power plant which is difficult to control accurately through conventional control approaches. The invention implements a machine learning approach to improve the operational performance of the control function over time, thereby to optimise the flow of 20wind through the wind park by controlling the yaw offset/axial induction factors of the wind turbines, which may achieve improved power production.

Abstract: A method of damping motion of a wind turbine, the wind turbine comprising a rotor and a floating platform. A motion signal is generated which is indicative of a motion of the wind turbine. A wind direction signal is generated which is indicative of a wind direction relative to the floating platform. A damping signal is generated on the basis of the motion signal and the wind direction signal, and the motion of the wind turbine is damped on the basis of the damping signal, for instance by adjusting the pitch of the rotor blades. A phase of the damping signal may be controlled on the basis of the wind direction signal.

Abstract: A method of calibrating a reference of a wind turbine. The method comprises monitoring performance of the wind turbine over a calibration period to generate performance data, wherein the calibration period comprises a series of sub-periods. The reference is calibrated by: setting the reference on the basis of the performance data; and, for each sub-period: determining a sub-period value on the basis of the performance data generated during that sub-period, comparing the sub-period value with the reference, and updating the reference with the sub-period value if the comparison shows that a performance of the wind turbine indicated by the sub-period value is better than a performance of the wind turbine indicated by the reference. The comparison and updating steps enable the reference to more accurately reflect more recent performance of the wind turbine. The method can also be reliably used in freezing temperatures.

Abstract: A robotic maintenance device (40) and method for repairing damage (26) around the leading edge (22) of a wind turbine blade (20) are provided. The maintenance device (40) includes a main chassis (42) that is configured to be mounted on the wind turbine blade (20), an applicator head (46) for applying a coating material (32) onto an exterior surface (30) of the blade (20) to cover and fill in damaged areas (26), and an environmental control module (60). The environmental control module (60) is located proximate the applicator head (46) and includes a tent (62) that selectively deploys over a portion of the leading edge (22) of the blade (20) behind operations of the applicator head (46) to define a curing zone. The coating material (32) within the curing zone can cure on the wind turbine blade (20) to complete the repair while remaining shielded from local environmental conditions such as wind and rain around the wind turbine blade (20). For example, the tent (62) can be configured to extend over a fixed length and move over that length behind the moving robotic maintenance device (40), or the tent (62) can be configured to secure on the blade (20) and be extended as the maintenance device (40) moves and conducts repair operations, with the tent (62) being retractable at the end of the maintenance process.

Abstract: A repair device and method for repairing damage around the leading edge of a wind turbine blade (20) are provided. The repair device includes a robotic maintenance device (40) and an unmanned aerial vehicle (UAV) (62) that can move the maintenance device (40) between a storage position and an operation position, the former being mounted on a blade (20) of the wind turbine (10). The UAV (62) hovers and remains connected to the maintenance device (40) during operations at the blade (20) to minimize a total operational downtime needed to conduct the repair actions. The UAV (62) is secured to the maintenance device (40) by at least one support line (68) that carries the weight load of the maintenance device (40) and at least two control lines (72) that prevent undesired rotations of the maintenance device (40), thereby improving precision and accuracy of UAV-driven movements of the maintenance device (40). A transport container (24) may also be provided to define the storage position, the transport container (24) including an elongated slot (70) for guiding movement of the lines (68, 72) and the maintenance device (40) during movements into and out of a storage space within the container (24).
