Abstract: A first aspect of the invention provides a wind turbine blade having a blade shell that defines a suction side, pressure side, leading edge, and a trailing edge of the blade. The blade further comprises a blade heating system comprising one or more heating elements configured to heat the blade in first and second heating areas, wherein the first heating area is closer to the leading edge than the second heating area is, and the heating system is configured to generate heat fluxes in the first and second heating areas such that the heat flux generated in the first heating area is lower than the heat flux generated in the second heating area.

Abstract: A method of inspecting a wind turbine blade. The wind turbine blade comprises an electro-thermal heating element and a surface protection layer. The method comprises: exposing a test point of the electro-thermal heating element; contacting the test point to establish an electrical connection between the test point and a sensor; and electrically connecting the sensor to the surface protection layer. The sensor is operated to measure a resistance value indicative of an electrical resistance between the test point and the surface protection layer. The resistance value is analysed to determine a condition of the wind turbine blade. The invention provides a method of inspecting a wind turbine blade which enables damage or defects to be detected which may be difficult to detect by visual inspection or traditional non-destructive testing techniques. For instance, the resistance value may give an indication of the presence of an electrical short between the heating element and the surface protection layer.

Abstract: The present invention relates to a method and controller for heating a wind turbine blade that comprises a plurality of heating zones. An icing factor is determined based on environmental conditions and one or more heating zones are determined based on the determined icing factor, wherein each heating zone comprises one or more Electro-Thermal Heating Elements. The one or more Electro-Thermal Heating Elements corresponding to the determined heating zones are activated to generate heat.

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 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.
