Wind turbine arranged for independent operation of its components and related method and computer program

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.

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.
