摘要： A wind turbine which is composed of several subunits is provided. Each of the several subunits includes a controller. Each of the controllers is adapted to operate in a cooperative mode and in an isolated mode. In the cooperative mode, one of the controllers operates as a master controller and the remaining controllers operate as slave controllers. In the isolated mode, each subunit is exclusively controlled by its respective controller, wherein each of the controllers acts as an independent master controller for its subunit. Further, a method for operating a wind turbine which includes at least two subunits is provided. Each of the at least two subunits includes at least one sensor, at least one actuator and a controller. The method for operating the wind turbine is carried out independently in each subunit and includes detecting at least one sensor signal; and determining and transferring a command to at least one actuator. Further, a segmented computer program for controlling a wind turbine which includes at least two subunits is provided.
