Abstract: A shear web foot for a wind turbine blade is described. The shear web foot extends longitudinally and comprises a base for attaching to an internal surface of the blade and first and second side walls. The side walls extend respectively from opposite longitudinal sides of the base. At least part of each side wall is inclined relative to the base and inclined towards the other side wall. A web-foot interior is defined at least in part by the base and the first and second side walls. One or more internal walls are located in the web-foot interior. The one or more internal walls extend between the base and the first and/or second side walls and are spaced apart from the first and second side walls to define a plurality of chambers within the web-foot interior.

Abstract: The invention relates to a wind turbine system with a plurality of wind turbine modules each with a rotor. A control system is arranged to execute a shutdown procedure with a first control command for terminating power production from a first subset of wind turbine modules resulting in a thrust force change with a reduced thrust force from the wind on a first part of the support structure carrying the first subset of wind turbine modules. A second control command is applied to a second subset of wind turbine modules for enabling thrust control of the second subset of wind turbine modules to oppose the thrust force change at the first part. Thus, there is obtained an improved and cost-effective way of stabilizing a wind turbine system with multiple rotors during shutdown.

Abstract: An assembly for a wind turbine, comprising a shaft extending within a main shaft housing. A radially outer portion of the shaft includes at least one engagement formation. A retention mechanism is moveable radially between a radially inward position in which the retention mechanism can engage the at least one engagement formation, such that rotation of the shaft is constrained, and a radially outward position in which the retention mechanism cannot engage the engagement formation, thereby allowing rotation of the shaft.

Abstract: A method for wind turbine tower damping is disclosed, as well as an associated controller and wind turbine. The method comprises generating, using at least a first sensor signal, a first pitch reference signal for one or more rotor blades of a wind turbine during partial load operation. The method further comprises determining, using at least a second sensor signal, dynamic state information for a tower of the wind turbine. The method further comprises generating a second pitch reference signal by adapting the first pitch reference signal using the dynamic state information. The method further comprises selecting a maximum pitch reference signal from the second pitch reference signal and a saturation pitch reference signal. The method further comprises communicating the maximum pitch reference signal to control a pitch of the one or more rotor blades.

Abstract: The invention relates to a method for the controlled and automatic tensioning of bolts pre-installed in a flange joint between a hub and a main shaft in a nacelle of a wind turbine as well as to a bolt tensioning system for such method. The method comprises arranging a fixture inside the nacelle and mounting a bolt tensioning tool to the fixture which is mounted movable in an axial direction and in a working area perpendicularly hereto. First the flange joint is rotated to position a first set of bolts within the working area of the bolt tensioning tool, and then the bolt tensioning tool is controlled alternately to move the tensioning tool into a position for tensioning a bolt and to tension the bolt, until all bolts of the first set of bolts have been tensioned. The rotation of the flange joint may be controlled by operating a rotation tool operably connected to the main shaft, gearbox, and/or generator.

Abstract: A renewable power plant configured to deliver electrical power to an electrical grid in accordance with a reference is disclosed. The renewable power plant comprises at least one energy generating system of a first type, at least one energy generating system of a second type, and a control system including a central power plant controller (CPPC) which generates setpoints for controlling the energy generating systems in accordance with the reference. The energy generating systems provide feedback signals to the CPPC. The control system is configured to generate a modified feedback signal based on the feedback signal received from the energy generating systems of the second type, and using a model representing operational behavior of the energy generating systems of the second type. The CPPC is configured to apply the modified feedback signal to a feedback control loop for controlling the energy generating systems.
