Software applications for wind turbine vibrations analysis

Abstract

In this paper is presented the implementation of a software for the analysis of vibration generated by wind turbines components. This software application was built in LabWiew programming environment and for vibration analysis and fault detection were used techniques as: wavelet analysis, envelope detection, FFT analysis, Cepstrum analysis, Vector RMS analysis. Vibration signal envelope detection was performed using a virtual instrument based on Hilbert transform and rms analysis was performed using virtual instrument ‘‘Vector RMS’’ specifically designed for vibration analysis. The experimental results were obtained by measuring the vibration signals of a bearing with a simulated fault on outer raceway.
