A method based on multifractal spectrum and support vector machine is proposed for fault identification of shafting system of hydropower units. Firstly
the multifractal spectrum algorithm is used to extract the feature data of vibration signals
and then the feature data is used as the input vector of support vector machine to realize the fault classification. The experimental data show that the method can accurately identify the common shafting faults
and provide a new method for the intelligent identification of shafting faults of hydropower units.
