Abstract: A wind turbine rotor blade spar cap includes a stack of layers of conductive material. An intermediate layer is bonded between adjacent layers of the conductive material. The intermediate layer includes a portion of conductive material which is electrically coupled to the adjacent layers of conductive material so as to equipotentially bond the adjacent layers of the conductive material via the intermediate layer.

Abstract: A method of securing a cable (22) to a wind turbine blade is described. The method involves providing a pre-assembled cable assembly (34) comprising a cable (22) and a plurality of mounts (40a-e) pre-attached to the cable (22) at intervals along the length of the cable (22). The plurality of mounts (40a-e) is attached to a surface (20) of a wind turbine blade such that the mounts (40a-e) are spaced apart along the surface (20) of the blade. The spacing between adjacent mounts (40a-e) when the mounts (40a-e) are attached to the blade is less than the length of the cable (22) between said adjacent mounts (40a-e) such that a predetermined amount of slack is provided in the cable (22) between said adjacent mounts (40a-e). A pre-assembled cable assembly for use in the method is also described together with a method of assembling the cable assembly.

Abstract: A wind turbine blade (2) comprising an outer shell (6) incorporating a metallic foil component (20), a conductive blade component (12) in-board of the metallic foil component (20), and a fabric sheet assembly (22) positioned between the metallic component (20) and the conductive blade component (12). The fabric sheet assembly comprises: one or more non-conductive fabric sheets (28, 30) which define first and second outer surfaces (24, 26) of the fabric sheet assembly (22); and at least one conductive thread stitch (34) penetrating a depth of the one or more fabric sheets (28, 30) and being exposed at the outer surfaces (24, 26); thereby to enable equipotential bonding between the conductive blade component (12) and the metallic foil component (20).

Abstract: There is provided a method of avoiding edgewise vibrations during a non-operational period of a wind turbine. The method comprises defining a non-operational period for a wind turbine arranged at a specific site, determining expected wind conditions at the specific site during the non-operational period and defining a plurality of potential yaw orientations for the wind turbine. The method further comprises determining the relative probability of edgewise vibrations occurring during the non-operational period for each potential yaw orientation based upon the expected wind conditions during the non-operational period, determining one or more preferred yaw orientations, which are the yaw orientations in which the probability of edgewise vibrations occurring is lowest, and arranging the wind turbine in one of the preferred yaw orientations during the non-operational period.

Abstract: A wind turbine blade comprising an electro-thermal heating element with a tapering width. The electro-thermal heating element comprises: electrically resistive sheet material; a first electrode which is in electrical contact with the sheet material and positioned at a first end of the element; and a second electrode which is in electrical contact with the sheet material and positioned at a second end of the sheet material. An electrically conductive strip extends across a width of the element. The sheet material has a first part on a first side of the strip and a second part on a second side of the strip. The strip is in electrical contact with the first and second parts of the sheet material. The first part of the sheet material has a first width, and the second part of the sheet material has a second width which is different to the first width.

Abstract: Examples of the present disclosure generally relate to wind turbine blades configured to minimize or eliminate buildup of ice on the blades. In order to maintain an ice free surface on a wind turbine blade, one or more ETH panels are embedded in the wind turbine blade to heat the wind turbine blade. One or more busbars are electrically connected to each of the one or more ETH panels for conducting electrical power to the ETH panels. The busbars may be disposed in an overlapping configuration to provide uniform heating of the wind turbine blade.

Abstract: The present invention relates to a method, controller, wind turbine and wind farm that advantageously determines an ice throw risk zone (302) for a wind turbine (301), wherein the ice throw risk zone (302) defines an area surrounding the wind turbine (301) within which ice can be thrown from one or more blades of the wind turbine (301); determining whether the determined ice throw risk zone (302) impinges one or more exclusion zones; and if the determined ice throw risk zone (302) impinges one or more exclusion zones, determining an alteration to one or more operating parameters of the wind turbine (301) in order to alter the ice throw risk zone (302) such that the determined ice throw risk zone (302) does not impinge the one or more exclusion zones.
