Abstract
A control system and a method for controlling operation of a wind turbine are disclosed. A first sensor and a second sensor are arranged for sampling or continuously measuring a first physical value and a second physical value being representative of a first physical impact and a second physical impact on components of the wind turbine in order to provide a first and a second control parameter for controlling operation of the wind turbine. The first and second control parameters are distinct. During active generation of energy the control system is adapted to selectively switch between controlling the operation of the wind turbine either on the basis of the first control parameter or on the basis of the second control parameter, i.e. to selectively switch between two different, distinct and independent control strategies. The two control strategies allow redundancy in control of the operation of the wind turbine. Both control strategies are based on measurements of actual physical impacts affecting the components of the wind turbine, thereby making it possible to control the wind turbine in a more optimal manner than when using prior art control systems and methods, regardless of which control strategy is selected.
