Abstract
The report describes measurements carried out on the Nordtank NTK 500/37 wind turbine during the period from September 1992 to September 1993. The measurements were carried out at Risoe located near Roskilde Fjord. The test site, the wind turbine, the data acquisition system and the calibration procedures are described. Measurements are made in accordance to a `system test` as described in the Danish rules for type approval and certification. The safety tests include breaking sequences at normal operation with and without tip brakes and runaway test. The tests are shown as time series. Dynamic response analysis of the wind turbine was carried out during standstill and at normal operational conditions at low and high wind speeds. Selected runs are shown as time tracks at low and high wind speeds. The structural loads are analyzed statistically. Ten minutes mean, standard deviation, maximum, and minimum values are shown as function of the wind speed. The fatigue loads including blade, rotor and tower loads are evaluated using rainflow counting. The equivalent load ranges are calculated at different wind speeds and turbulence, and at forced yaw misalignments. (au) (11 tabs., 123 ills., 5 refs.)
