First measurements on DANmark 36 - 525 kW wind turbine.

摘要

The report contains the first measurement results on the DANmark 36 - 525 kW wind turbine operating at Hanstholm, Denmark. The power spectral density functions were calculated from the records of the torque and bending movements, the data were sampled at 25 Hz. Tests were taken at stopped rotor, using several methods for mechanical excitation. The eigenfrequences of tower bending, rotor and transmission torsional, blade flapwise and blade chordwise are given in addition to the power and turbulence curves and data time tracks. The influence of the site topography on the performance of the windmill is also dealt with. (AB).
