Abstrakt:

The paper describes the study of the dynamic properties of a 1,3 MW wind turbine Izar Bonus 62 using two different measurement types: accelerations and strains. The blades of this wind turbine were fitted with 1,5 m extensions with the purpose of increasing the wind turbine’s swept area enabling it to capture further wind energy.

The main objective of the study was to identify the modal properties of the rotor and tower (natural frequencies, damping ratios and mode shapes) before and after the extension of the blades in order to compare with the results from numerical analysis and to evaluate the possibility of appearance of resonance problems. With this purpose, ambient vibration tests and a rotor-stop test were conducted and the results obtained before and after the extension were analyzed in order to validate the adequate performance of the wind turbine after extension of the rotor blades.
