Weak characteristic information extraction from early fault of wind turbine generator gearbox

Xiaoli XU, Xiuli LIU

Frontiers of Mechanical Engineering 2017, Volume 12, Issue 3, Pages 357-366 doi: 10.1007/s11465-017-0423-4

Abstract:

Given the weak early degradation characteristic information during early fault evolution in gearboxof wind turbine generator, traditional singular value decomposition (SVD)-based denoising may resultin loss of useful information.A weak characteristic information extraction based on µ-SVD and local mean decompositionthat this method can significantly weaken signal noise, effectively extract the weak characteristic information
