Kurzbeschreibung (Abstract)
This paper examines the possibility of contactless monitoring of wind power plants with a 2D profile scanner. Before measuring real wind power plants the concept was tested under laborato-ry conditions. With simulated oscillations between 0.1 Hz and 10 Hz the qualification to detect move-ments of artificial structures with the measurement system was proven. The measurement campaign (still in progress) was carried out at two different wind power plants south of Darmstadt. The two wind power plants are quite contrary, they differ from each other in the following points: age, hub height, speed, power control and power output. The data acquisition and data handling is pre-sented together with problems and an outlook how to overcome them with the combination of profile scanning and an image assisted total station (IATS). The first analysis of the measured data was realized with the discrete Fourier transformation (DFT). In the following, the limitations of this method in this particularly application are shown and an alterna-tive is proposed with the discrete wavelet transfor-mation (DWT).
