Abstract :
Renewable energy generation strongly relies on wind power aside from water power plants. Technical and economical growth rules ("The larger, the better") yield systems of increasing power now far in the Megawatt range. Wind power rotor blades have to withstand high mechanical stress by standard and disturbed operation through centrifugal and power transmission forces. Especially, heavy wind gusts create critical situations for the mechanical survival of the rotor blades. A converter between machine and grid enables a high rate of control opportunities. A design is developed for active minimisation of stress peaks and damping of oscillations by specific control interception in generator torque control
