| 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. |
