    Abstract: Method of operating a wind turbine comprising a plurality of blades rotatable along their longitudinal axes using a pitch mechanism, and comprising one or more movable trailing edge surfaces. The method includes predicting, at a first moment in time, a high load for one or more of the blades at a second moment in time. The method further comprises actuating on one or more of the movable trailing edge surfaces of these blades such that the trailing edge surfaces have a wider range of control to counteract the predicted high loads before the second moment in time, and simultaneously pitching the blades such as not to negatively affect the operation of the wind turbine. The method furthermore comprises, at the second moment in time, actuating the one or more movable trailing edge surfaces of the at least one or more blades to counteract the high loads.

    Abstract: A wind turbine that includes a rotor and a generator is described. The rotor includes a rotor hub that is rotatably mounted on a frame and one or more rotor blades. The generator includes a generator stator and a generator rotor with a carrying structure that carries magnetic or electromagnetic elements. One or more circumferentially arranged substantially axial protrusions that extend into the generator rotor carrying structure are attached to the rotor. Flexible couplings are arranged between one or more of the axial protrusions and the carrying structure.

    Abstract: Said hydraulic turbine includes a wheel which is made to rotate about a rotational axis (X2) by a main water stream (F1) going from a penstock to a suction tube along a flow path that passes through the wheel. Said turbine also includes first means that are placed outside the flow path of the main water stream (F1) and enable the mixing of a secondary water stream (F2), taken from the flow path and located upstream from the wheel, and an oxygen-containing gas (A2). Said turbine also includes second means for injection, downstream from the wheel of the turbine, a water/gas mixture (F3) produced in the first means.

    Abstract: Primary blade modules for a wind turbine blade are provided comprising a first blade shell, two opposed spar caps, and at least one shear web. The first blade shell has a root end and a first coupling end configured to be coupled with a secondary blade module. The two opposed spar caps have respective first spar cap portions extending along the first blade shell substantially from the root end to the first coupling end of the first blade shell, and respective second spar cap portions extending beyond the first coupling end. The at least one shear web extends between the opposed spar caps at least partially along the respective first spar cap portions. Secondary blade modules, systems for transporting primary blade modules, and methods of assembling (in situ) wind turbine blades having a primary blade module and a secondary blade module are also provided in the present disclosure.

    Abstract: Hoisting systems are provided for mounting a hub on top of a tower, the hub carrying a first and a second blade forming a bunny ears configuration, and a third blade. The system comprises a crane for pulling up the hub to the top of the tower, and a blade support for supporting the third blade at a supported blade portion. The system further comprises a hub-blade coupling device configured to assist in coupling a root portion of the third blade to a coupling portion of the hub. The hub-blade coupling device comprises a hub mount structure configured to be removably fixed to the hub, a blade mount structure configured to be removably fixed to the third blade, and a connector rotatably coupling the hub mount structure and the blade mount structure. Methods are provided of mounting a hub on top of a tower by using any of said systems.
