  • Control system and a method for controlling a wind turbine
    Patent number: 8546967
    Abstract: A control system for controlling operation of a wind turbine, a wind turbine having such a control system and a method for controlling a wind turbine are disclosed. The control system comprises a first sensor device and a second sensor device, each being arranged for measuring the same control parameter used for controlling operation of the wind turbine. The first sensor device has a first set of operating failure conditions, and the second sensor device has a second set of operating failure conditions. The first set of operating failure conditions comprises at least one operating failure condition which does not form part of the second set of operating failure conditions. The system further comprises a third sensor device for detecting an operating failure condition of the first sensor device and/or of the second sensor device.
