Wind turbine arranged for independent operation of its components and related method and computer program
First Claim
1. A wind turbine comprising:
- several subunits, each of the subunits comprising a controller,wherein each of said controllers is adapted to operate in a cooperative mode and in an isolated mode,wherein, in the cooperative mode, one of said controllers operates as a master controller and the remaining of said controllers operate as slave controllers to the master controller,wherein, in the isolated mode, each subunit is exclusively controlled by the respective controller and there is no direct communication among said controllers, each of said controllers acting as an independent master controller for the respective subunit, andwherein each of the slave controllers is switchable from the cooperative mode to the isolated mode in response to an unexpected command from the master controller or unexpected data from a sensor of the wind turbine.

Abstract
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.

11. A method for operating a wind turbine comprising at least two subunits, each of the at least two subunits comprising at least one sensor, at least one actuator and a controller, comprising:
-
detecting at least one sensor signal; determining and transferring a command to the at least one actuator; operating the wind turbine in a cooperative mode comprising operating one of the controllers as a master controller controlling the operation of the wind turbine and operating each of the remaining of the controllers as a slave controller to the master controller; operating each of the controllers independently during operation of the wind turbine in an isolated mode, wherein in the isolated mode, the detecting and the determining and transferring are carried out independently in each subunit and there is no direct communication among the controllers; and during operating of the wind turbine in the cooperative mode, after receiving an unexpected command from the master controller or an unexpected signal from a sensor of the wind turbine, causing each slave controller to switch to a master mode and operate in the isolated mode. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A non-transitory computer readable medium encoded with a segmented computer program for controlling a wind turbine comprising at least two subunits, the segmented computer program comprising at least two computer program parts for controlling the respective subunits, the at least two computer program parts enabling
detecting of sensor signals; -
determination and transfer of commands to actuators; operation of the wind turbine in a cooperative mode wherein one of the at least two computer program parts operates as a master controller controlling the operation of the wind turbine and each of the remaining of the at least two computer program parts operates as a slave controller to the master controller; operation of the wind turbine in an isolated mode wherein the at least two computer program parts are operable to control the respective subunits independently of each other and there is no direct communication among the at least two computer program parts; and during operation of the wind turbine in the cooperative mode, after receiving an unexpected command from the master controller or an unexpected signal from a sensor of the wind turbine, causing each slave controller to switch to a master mode and operate in the isolated mode.
