Abstract
The proposed method for rolling bearing fault diagnosis in wind turbines is based on STOA-XGBoost,aiming to ensure the smooth operation of wind turbines and enhance the reliability of the diagnostic process.Initially,fault characteristics are extracted from vibration signals through time-domain analysis.The Ultern optimization algorithm is employed to optimize hyperparameters of the extreme gradient lifting tree,so as to promote model generalization and prediction accuracy.Subsequently,the trained model is utilized for efficient fault diagnosis in wind turbines.Experimental results demonstrate that the proposed diagnostic model effectively identifies rolling bearing faults.
