摘要：

This contribution describes the application of Operational Modal Analysis (OMA) to a 2 MW wind turbine rotor. The rotor spans a total diameter of 100 m and is lying on the ground for the measurement campaign. Due to a limited time span and for accessibility reasons modal testing of the rotor is performed on one blade only. Overall 13 PCB accelerometers are positioned along the blade in flapwise and edgewise directions, and the measurement duration is set to one hour. Furthermore, a multibody model of the rotor configuration is built up to support the interpretation of the OMA results from the blade with respect to the overall rotor system. The modal quantities identified by OMA are then compared to calculated values by Multibody Simulation (MBS) to investigate the quality of the modelling approach of the blades used in MBS. Findings from this investigation then allow conclusions to be drawn about the quality of existing turbine models with the same rotor model.
