Abstract
A control system for a wind turbine is provided. The control system includes a plurality of controllers distributed in the wind turbine or the wind power plant; and a plurality of data storage units, each data storage unit being arranged at a respective predetermined position in the wind turbine or the wind power plant and being coupled to the controller arranged at the same position; wherein each data storage unit comprises operational information pertaining to the predetermined position in the wind turbine or the wind power plant; and wherein each controller is configured to read the operational information of the corresponding data storage unit and to determine its function from the operational information.
Claims23
A control system for a wind turbine or a wind power plant, the control system comprising:
- a plurality of controllers distributed in the wind turbine or the wind power plant;
- a plurality of data storage units, each data storage unit being arranged at a respective predetermined position in the wind turbine or the wind power plant and being coupled to a corresponding one of the plurality of controllers arranged at the same position;
- wherein each data storage unit comprises operational information pertaining to the predetermined position in the wind turbine or the wind power plant, and
- wherein each controller is configured to read the operational information of the corresponding data storage unit and to determine its function from the operational information;
- and
- a first main controller coupled to the plurality of controllers, wherein the first main controller is configured to determine if the plurality of controllers have a correct hardware and software configuration based on hardware and software configuration information received from the plurality of controllers and the operational information received from the corresponding data storage units, wherein the first main controller is further configured to prevent start-up of the wind turbine or a wind power plant sub-system and to provide a warning signal when it is determined that at least one of the plurality of controllers has one or both of a wrong hardware configuration and a wrong software configuration,
- wherein at least one of the plurality of controllers is arranged at a wrong position in the wind turbine or the wind power plant or at least one of the plurality of controllers receives the wrong operational information from the corresponding data storage unit.
