Description

A field test on a stall regulated wind turbine with a rated power of 400 kW at Karimata, Miyakojima Island was carried out to investigate structural parameters as well as wind loads and responses of the turbine. The lower natural frequencies of wind turbine such as 0.81Hz and 2.43Hz coincided with the first natural frequencies of the tower and blades. The damping ratios of the tower were around 1% in the fore-aft direction and 0.6% in the side-side direction, respectively. The strains obtained at the root of the tower were used to estimate the tower bending moments. A FEM code was developed to predict natural frequencies and wind loads on the turbine. The maximum, the mean and the standard deviation of tower bending moments predicted by the full dynamic simulation show a good agreement with the measurements.
