Abstract
The potential to reduce fatigue loads by control system design has been investigated in a joint R&D project carried out by ISET and LBF. On a 33 kW experimental wind converter located in a mid-range mountainous region an extensive measurement program was carried out to determine the loading of the different components in dependence of the controller design. The results of the investigations show that mechanical loads can be reduced by a suitable control method for wind energy converters with variable speed. Especially the load spectra of the flapwise blade bending moment, of the drive shaft torsion and the tower bending moments show a significant reduction.
