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: The invention relates to a wind turbine system (1) comprising a support structure (3) with a plurality of wind turbine modules (2) mounted to the support structure (3). A control system (20) is arranged to enter a service mode wherein service can be performed in the wind turbine system (1) by applying a first control command (1CC) to a first subset of wind turbine modules (2') for terminating power production. A second control command (2CC) is applied to a second subset of wind turbine modules (2'') for bringing the second subset of wind turbine modules (2'') 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 (2*) of the first subset of wind turbine modules. An improved stability of the wind turbine system during service is thereby obtained.
Abstract translation: 风力涡轮机系统（1）包括具有安装到支撑结构（3）的多个风力涡轮机模块（2）的支撑结构（3）。 控制系统（20）被布置成进入服务模式，其中可以通过将第一控制命令（1CC）应用于风力涡轮机模块（2'）的第一子集来在风力涡轮机系统（1）中执行服务，以用于终止功率 生产。 将第二控制命令（2CC）应用于风力涡轮机模块（2“）的第二子集，以使风力涡轮机模块（2”）的第二子集进入阻尼模式，其中第二风力涡轮机模块 子集被操作和/或定位以主动地和/或被动地减弱风力涡轮机模块的第一子集的至少一个风力涡轮机模块（2 *）的振动。 由此获得风力涡轮机系统在服务期间稳定性的改善。
