Abstract: There is presented a method for controlling a rotor on a wind turbine, wherein the rotor is comprising one or more blades, and wherein the wind turbine is comprising a pitch system, the method comprising: Operating the rotor in a standstill or idling operating state, determining or receiving one or more control parameters, where the control parameters enable determining one or more yawing parameters may be described as a function of the one or more control parameters, wherein the one or more yawing parameters comprises one or more of: An angular yawing velocity of the a yawing section, an angular yawing acceleration of the yawing section, and/or a yawing moment applied by the yawing section on a remainder of the wind turbine, and pitching based on the one or more control parameters one or more blades of the rotor with the pitch system.

Abstract: A method for controlling a multirotor wind turbine comprising two or more energy generating units is disclosed. At least one load carrying structure is connected to a foundation or to a tower via a yaw arrangement, and the load carrying structure carries the at least two energy generating units. A requirement to a change in operation of at least a first of the energy generating units is detected. Control commands for the first energy generating unit and for at least a second energy generating unit, mounted on the same load carrying structure, are generated. The control commands cause the required change in operation, and the control commands cause coordinated operation of at least the first energy generating unit and the second energy generating unit. The control commands are generated under the constraint that a yaw moment of the yaw arrangement is maintained below a predefined threshold level.

Abstract: According to a first aspect of the invention, there is provided a wind turbine blade having a split blade configuration, comprising a first blade module defining an aerofoil profile and a second blade module defining an aerofoil profile; a damping module intermediate the first blade module and the second blade module; wherein the damping module comprises a first blade interface for joining to the first blade module and a second blade interface for joining to the second blade module. The damping module comprises a vibration damping unit.
Beneficially, the invention provides a useful way in which to integrate motion damping functionality into a modular wind turbine blade.
