  • Thrust balance control of a multirotor wind turbine based on constraints
    Patent number: 11384730
    Abstract: A method for controlling a multirotor wind turbine is disclosed. A first operational state of each of the energy generating units of the wind turbine is obtained. A difference in thrust acting on at least two of the energy generating units 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 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 is controlled in accordance with the new operational states for the energy generating units.

  • Wind turbine system with damping during service
    Patent number: 11041480
    Abstract: The invention relates to a wind turbine system comprising a support structure with a plurality of wind turbine modules mounted to the support structure. A control system is arranged to enter a service mode wherein service can be performed in the wind turbine system by applying a first control command to a first subset of wind turbine modules for terminating power production. A second control command is applied to a second subset of wind turbine modules for bringing the second subset of wind turbine modules into an damping mode where each of the wind turbine modules of the second subset is operated and/or positioned to damp vibrations, actively and/or passively, of at least one wind turbine module of the first subset of wind turbine modules.
