Abstract: Embodiments herein describe operating a control system for a wind turbine in a first mode and second mode of operation. When in the first mode, the wind turbine provides power to a local AC grid. However, when in the second mode, the wind turbine provides power to a high-voltage direct current (HVDC) link. The control system includes a reactive power control leg and an active power control leg. To switch from the first mode to the second mode, the control system activates a PI controller coupled between the reactive and active power control legs which increases the output voltage of the wind turbine until the magnitude of the voltage activates a diode rectifier and permits the power outputted by the wind turbine to be transmitted along the HVDC link.

Abstract: The invention relates to a method of preparing a wind turbine blade with a leading edge protection. The method includes applying a first layer of paint on the surface portion comprising the part of the leading edge to be protected, applying a layer of a fibrous material on top of the first layer of paint, applying a second layer of paint on the layer of fibrous material, and allowing the applied leading edge protection to cure. The method may be performed as a part of the manufacture of the blade and/or as a post-processing step for example during repair on site. The proposed method results in an increased erosion resistance and improved protection against impacting particles. The invention further relates to a wind turbine blade comprising a leading edge protection established as mentioned above.

Abstract: A method is provided for handling wind turbine blades aboard a vessel, the method including providing on the vessel a blade rack assembly configured to accommodate more than one blade, the rack assembly having at least a root rack and a tip rack, and the root rack and tip rack defining between them a blade support plane. The method also includes providing a jack acting between the vessel and one of the root or tip rack; and raising or lowering one of the root or tip rack aboard the vessel by the jack to thereby move the blade support plane through an elevation angle θ. A jack assembly on a wind turbine installation vessel and an offshore wind turbine installation vessel are also provided, each capable of raising or lowering a rack of wind turbine blade root or tip support frame elements.

Abstract: A power pack [2] is located within a housing [3] on the platform [1] of a wind turbine generator tower. The power pack [2] is supplied from a fuel tank [4]. With the door [6] of the housing [3] open, the power pack [2] may be removed for servicing and repair by using a U-shaped support structure [8] to which an electric motor [11] is mounted. Two support rails [12] permanently located within the housing [3] support the housed power pack [2]. A chain [15] attached to the power pack [2] is driven by the motor [11] to remove the power pack [2] from the housing [3] by sliding the power pack [2]along the support structure [8]. A pulley arrangement reduces the necessary torque. After removing the power pack [2] from the housing [3], a crane [7] is used to lift the power pack [2] from the platform [1] and to lower it down to a sea vessel [17]. The crane [7] may also be used in the refilling of the fuel tank [4] by hauling a fuel line [18] from a sea vessel up to the platform [1] and connecting it to the fuel tank [4].

Abstract: A wind turbine power generation facility includes: at least one wind turbine power generating apparatus; a lightning sensor for detecting or predicting occurrence of lightning in an installation area of the at least one wind turbine power generating apparatus; and a controller for switching an operation mode of the at least one wind turbine power generating apparatus to a lightning-protection mode in which a rotor rotation speed is lower than a rated rotation speed, on the basis of an output signal of the lightning sensor.

Abstract: A method of controlling a floating-body wind turbine power generating apparatus including a wind turbine generator disposed on a floating body includes a pitch-angle increasing step of increasing a pitch angle of a blade of the wind turbine generator when the wind turbine generator is stopped, so that an aerodynamic braking force is applied to a rotor of the wind turbine generator. In the pitch-angle increasing step, a first change rate of the pitch angle of the blade in a first period during which the wind turbine generator is in an inclining motion toward an upwind side from a vertical direction due to sway of the floating body, is smaller than a second change rate of the pitch angle of the blade in a second period during which the wind turbine generator is in an inclining motion toward a downwind side from the vertical direction due to the sway of the floating body.
