Noise study for wind turbine blade vibration signals based on fast ICA algorithm

The blade vibration of the wind turbine is mainly caused by the natural vibration of the blade, the random vibration of the wind and vibration of the bearing of the input side. Collecting vibration wave on the blade and surrounding, then separate the independent waveforms from the collected waveforms by fixed point fast separation (Fast ICA) algorithm, finally, make analysis of the spectrum of the independent waves through the fast Fourier.
