Wavelet Module of MATLAB Applies on Wind Turbine

Abstract:

Because of special running condition, it is very difficult to maintain and detect wind turbines. In order to reduce waste of financial cost and people and cut down cost of maintain and the repair of schedule .In order to change traditional repair of schedule into state repair, We need to improve the inspect accuracy. By introducing the wavelet analysis module of Matlab in the article and according to the analysis of measure vibration signal from SUT-1000 wind turbine which is designed by Shenyang University of Technology, and apply wavelet theory to analyze the data. we can get intuitionistic envelopment spectral line .Therefore, we can get practical and accurate run condition, put forward applicable report, and realize function of inspecting wind turbine on line.
