Vibration testing and controlling for wind turbine generator

Abstract

:--Generator is the key composition of wind turbines. The vibration of generator would accelerate the wear of its parts and shorten the service life, at the same, the vibration are easy to evoke the vibation of neighbor devices that would make lots of noise, so the study on the techonology of vibration testing and controlling for generator has important significance to the safe and efficient operation of generator, even wind turbines. This paper performs vibration testing on three over-vibration generator, and the collected vibration signals are analyzed , the causes of the over-vibration are illustrated, then the actions of vibration controlling are adopted, finally, the over-vibration are controlled efficiently. This studies has instructional significance and referenced value for the over-vibration adjustment and controlling in the running scene. .
