Abstract: A method for operating a wind turbine (1) with hinged wind turbine blades (5) is disclosed. The wind turbine (1) comprises an adjustable biasing mechanism (8, 10, 11) arranged to apply an adjustable biasing force to each wind turbine blade (5) which biases the wind turbine blade (5) towards a position defining a minimum pivot angle or towards a position defining maximum pivot angle. A biasing force is selected for each wind turbine blade (5) and the selected biasing force is applied to the respective wind turbine blades (5). The wind turbine (1) is operated while monitoring rotor unbalance of the wind turbine (1). In the case that the rotor unbalance exceeds a first threshold value at least one of the wind turbine blades (5) is selected, and the biasing force applied to the selected wind turbine blade(s) (5) is adjusted.

Abstract: The present invention relates to a multirotor wind turbine comprising at least two rotor nacelle assemblies mounted to a support arrangement via respective yawing systems, and a toe angle control system for controlling the toe angles of the rotor nacelle assemblies with respect to the 5 support arrangement; wherein the toe angle control system is configured to operate in a first mode in which the rotor nacelle assemblies are held at positive toe angles while the wind turbine is generating power in a main production mode; wherein the toe angle control system is further configured to monitor the operating mode of the wind turbine, and to switch to a second mode in which the yawing systems of the rotor nacelle assemblies are operated to 10 reduce the toe angles of the rotor nacelle assemblies if an operating mode-based trigger condition has been met.

Abstract: The invention relates to a method for detecting and controlling whirling oscillations of the blades of a wind turbine. The detection of the whirling oscillations is based on measurement signal indicative of blade oscillations, and a rotation-transformation of the measurement signal from a measurement frame into at least one target frame based on the whirling oscillation frequency. The rotation-transformation comprises a backward or forward rotation transformation direction relative to a rotor rotation direction. The control is based on an oscillation component obtained from the rotation-transformed measurement signal where the oscillation component is indicative of the whirling oscillation in the backward and/or forward rotation direction.

Abstract: A method for controlling a multirotor wind turbine (1) is disclosed. A first operational state of each of the energy generating units (5) of the wind turbine (1) is obtained. A difference in thrust acting on at least two of the energy generating units (5) is detected. At least one constraint parameter of the set of operational constraints is adjusted in accordance with prevailing operating conditions and in accordance with the detected difference in thrust, and a new operational state for at least one of the energy generating units (5) is derived, based on the at least one adjusted constraint parameter, the new operational state(s) counteracting the detected difference in thrust. Finally, the wind turbine (1) is controlled in accordance with the new operational states for the energy generating units (5).

Abstract: A system (24) and method are described herein for manufacturing a wind turbine blade (22) proximate to the final installation site of a wind turbine (10). The system (24) includes a creel (72) of feeders (74) configured to apply strengthening elements (62) onto a plurality of shell core sections (26) coupled together and fed through the creel (72). The shell core sections (26) include an external surface (56) with a plurality of external grooves (58) recessed into the external surface (56) such that the strengthening elements (62) are laid into the external grooves (58). The system (24) also includes a deposition station (78) configured to apply an outer surface material layer (82) in fluid form to cover the external surface (56) and the plurality of strengthening elements (62). A curing station (86) heats and consolidates the shell core sections (26), the strengthening elements (62), and the outer surface material layer (82) together into a final consolidated part, with the outer surface material layer (82) defining an external profile of the blade (22) following curing.
