    Abstract: Apparatus for treating a surface of a wind turbine blade, comprising an expandable structure that is deployable from a collapsed state into an expanded state in which the structure defines an elongated treatment zone into which a blade is receivable in use. The apparatus includes treating means arranged to apply a treatment in the treatment zone. Also provided is a method for treating a wind turbine blade including: positioning a wind turbine blade in a substantially vertical orientation; locating an expandable structure adjacent the wind turbine blade; deploying the expandable structure about the blade such that the expandable structure defines an elongated treatment zone which receives at least part of the blade; and applying surface treatment to the surface of the blade using the expandable structure.

    Abstract: The disclosure relates to a method, as well as a related wind turbine and computer program product, for use with a wind turbine comprising a wind turbine controller. The method comprises determining the wind turbine to be in a first operational state, and operating a control system of the wind turbine using the wind turbine controller. The method further comprises determining the wind turbine to be in a second operational state, and operating the control system using an auxiliary controller. Operating the control system using the auxiliary controller comprises receiving a first control signal for the control system from the wind turbine controller, transmitting a feedback signal to the wind turbine controller in accordance with the first control signal, and transmitting a second control signal to the control system as a substitute for the first control signal.

    Abstract: The disclosure provides a method of controlling a wind turbine, wherein the method comprises: a) measuring and recording power output values from a sensor, and measured values from at least one of a rotor speed sensor, rotor speed controller, pitch controller or pitch position sensor for the wind turbine, during operation of the turbine with a reference pitch angle and/or rotor speed regulation curve for a time period t1; b) changing the pitch angle and/or rotor speed regulation curve(s); c) operating the wind turbine with the curve(s) from step b) during a time period t1 and receiving measured values from a wind turbine power output sensor and at least one of a rotor speed sensor, rotor speed controller, pitch controller or pitch position sensor; d) optionally repeating steps b) and c) one or more times; e) comparing a power output of the wind turbine obtained at step a) with a power output obtained in step c) during operation of the wind turbine under one or more changed pitch angle and/or rotor speed regulation curve(s); f) determining whether a power output obtained at step c) is higher than a power output obtained at step a); and g) optionally, changing the pitch angle and/or rotor speed reference curve(s) for the wind turbine to a curve or curves identified in step f) that results in higher power output than the power output measured in step a). A computer programme implementing the method, a controller configured to execute the method and a wind turbine comprising the controller are also provided.
