The rotor and mast of a wind turbine can oscillate even in normal operation. The analysis of these oscillations plays an important role when the equipment is being developed and maintained. Up to now, this analysis has only been possible at discrete points located directly on equipment. The Fraunhofer Institute of Optronics, System Technologies and Image Exploitation IOSB uses modern information technology to remotely measure the oscillatory pattern over the entire structure of the facility from
“Wind turbines oscillate with displacements of up to a meter in magnitude, even at normal wind speeds. This represents a large load for the material, which can lead to damage and worst case to failure of an installation,” says Dr. Ilja Kaufmann from the Optronics Department of IOSB in Ettlingen. For this reason, operators continuously check how strong the oscillations ar...
