The incipient fault feature of offshore wind turbine rolling bearing is difficult to extract. A fault diagnosis method for offshore wind turbine rolling bearing based on variational mode decomposition(VMD) method is proposed. Considering the number of mode components has great influence on the decomposition results, the general principles of determination(More)
Wind turbines have been developed fast in the recent years and at the same time have brought some problems because they suffer higher reliability risk being exposed to extreme running environment and subject to constantly variable loadings. A fault tree model has been established from the basic components failure mode of wind turbine drive system. In the(More)
