Abstract

To address the issue of low accuracy in estimating the instantaneous frequency of wind turbines using a single vibration or current signal

this paper proposes a method for rotational frequency estimation and gearbox fault diagnosis based on the deep integration of vibration and rotor current signals. The goal is to improve the accuracy of gearbox fault diagnosis in wind turbines. Firstly

the vibration and rotor current signals are denoised using the Variational Mode Decomposition method and low-pass filtering

respectively. The instantaneous frequency curves of the vibration and rotor current signals are then obtained using synchroextracting transform

and the time-frequency curves of both signals are preprocessed to obtain two time-frequency curves of the wind turbine. Subsequently

a DA-BLCNN deep network model is proposed to fuse the instantaneous frequency curves of the gearbox fault bearing. Finally

an order tracking algorithm is used to resample the gearbox vibration signal at equal angles

enabling fault detection of the gearbox. Through experimental validation of bearing faults in the gearbox under varying speeds

it can be concluded that the method proposed in this paper can effectively achieve fault diagnosis of the gearbox.
