    Abstract: The present invention provides a method of operating a wind turbine having a rotor with a plurality of blades, a system for determining one or more loads on the wind turbine, a historical register of data on the wind turbine operation, and a control system for controlling one or more operational parameters of the wind turbine. The method comprises determining the loads on the wind turbine, and storing the determined loads on the wind turbine in the historical register. The method further comprises obtaining, from the historical register, a characteristic indicative of the loads on the wind turbine accumulated over time, and determining one or more wind thrust limits depending on the obtained characteristic indicative of the loads accumulated over time. One or more operational parameters of the wind turbine are controlled to keep the wind thrust on the wind turbine within the determined wind thrust limits.

    Abstract: Methods and arrangements for controlling the tension of tensioning cables in precompressed towers are disclosed. The towers may comprise a tower section (5), a pair of flanges (15, 15′), a plurality of tensioning cables (10A-10D) and at least one tensioner (30AB, 30CD). The pair of flanges may be arranged around an upper and a lower part of the tower section. The at least one tensioner may be arranged between two of the plurality of tensioning cables (10A-10D). The tensioner may pull the tensioning cables in response to a load signal to increase the tension.

    Abstract: Methods for determining a yaw angle and a pitch angle cycle for a wind turbine are disclosed. The methods comprise measuring during a measuring time a wind speed and a wind direction at a plurality of measuring heights between the maximum and minimum height at the wind site, determining an average wind speed and an average wind direction for each of the measuring heights during the measuring time, and determining a wind speed distribution and wind direction distribution between the maximum height and the minimum height, and determining one or more yaw-pitch combinations of yaw angle and pitch angle cycles as a function of an azimuth position of a rotor blade that lead to a desired angle of attack along the rotor swept area. The present disclosure further relates to methods of operating a wind turbine and suitable wind turbines.

    Abstract: When traversed by a flow of water, a hydraulic machine rotating part rotates around an axis of rotation. It includes runners which are distributed around the axis of rotation and each extend between a leading edge and a trailing edge. Each runner can include a first part which defines its leading edge and a second part which is attached to the first part and defines the trailing edge at least in part. The second part can be elastically deformable or displaceable in a reversible manner with respect to the first part, under the action of the flow of water, the second part defining, when the machine operates, the direction of the flow of water downstream of the runner.

    Abstract: The invention relates to a wheel (R) of the Francis type that comprises a ring (1) with revolution symmetry about the rotation axis (Z) of the wheel (R), and curved blades (21, 22) connected to the ring (1) and each having an outer peripheral edge (212, 222) and an inner central edge (211, 221). The connection points (B21, B22) between the ring (1) and the inner central edges (211, 221) of the blades (21, 22) are located on a same circle (C20) centered on the axis (Z). The connection points (A21, A22) between the ring (1) and the outer peripheral edges (212, 222) of the blades (21, 22) are located on at least two distinct circles (C21, C22) (D21, D22) centered on the axis (Z).
