Abstract: A load carrying structure (3) for a multirotor wind turbine (1) is disclosed. The load carrying structure (3) comprises a first load carrying arrangement (4) and a second load carrying arrangement (4), and each load carrying arrangement (4) comprises a primary structure (9) and at least two secondary structures (10), the secondary structures (10) extending on opposing sides of the primary structure (9) between an energy generating unit (5) carried by the load carrying arrangement (4) and an attachment point at a tower structure (2). Gravity acting on the energy generating units (5) causes push in the primary structures (9) and pull in the secondary structures (10), thereby causing preload of the secondary structures (10). The load carrying structure (3) is capable of handling thrust loads.

Each of the upper and lower sections includes an inwardly directed flange (82, 90) having a plurality of through-bores (84, 92, 96). An annular member (62, 120) has one or more ears (50, 204) that extend outwardly. Each ear (50, 204) is configured to be coupled to one of the plurality of cables (20). The annular member (62) includes a plurality of bores (68, 72, 104) that align with the through-bores (84, 92, 96) in the inwardly directed flanges (82, 90).

Abstract: A method of yawing a nacelle in a wind turbine having a yawing assembly comprising a drive-ring and a plurality of drives configured to exert a torque during movement along the drive-ring and thereby move the nacelle relative to the tower. The drive-ring is made of drive-ring segments joined in intersections. The method comprises defining a location for each intersection, defining a reference torque exerted by the drives when moving along the drive-ring, defining a reduced torque being lower than the reference torque, determining when a crossing drive moves across the location of an intersection, and to increase the lifetime, exerting the reduced torque by the crossing drive.

Abstract: The invention relates to a method for controlling a wind turbine system, more particular for a controlled sliding strategy to lower loads on the yaw system by controlling mechanical brakes and motor brakes in the yaw drive actuators. 5 When the yaw system (300) being in the non-yawing operational state, and the mechanical brake(s) (400) being in an engaged state, and the yaw controller (308) determines or receives a signal indicative of a yaw moment, and if the signal indicative of a yaw moment is above a signal threshold, then the yaw controller (308) sends a braking signal to the yaw drive actuators to enter the 10 motors into the brake state to apply a braking torque.

Abstract: A method for controlling a yaw system (1) of a wind turbine is disclosed. The yaw system (1) comprises a toothed yaw ring (2) connected to one of a tower (8) or a nacelle (7) and an active yaw mechanism comprising at least one yaw drive (3) connected to the other of the tower (8) or the nacelle (7). Each yaw drive (3) comprises a pinion (5) configured to be arranged in engagement with the toothed yaw ring (2) and a drive mechanism (6) configured to drive the pinion (5). In the case that a wind speed and/or a turbulence and/or wind driven loads on the wind turbine exceeds a predefined threshold value, the active yaw mechanism is decoupled by decoupling at least the drive mechanism (6) of at least one of the yaw drives (3) from the yaw system (1). Subsequently the nacelle (7) is allowed to perform yaw movements relative to the tower (8) by means of free yawing.
