During the long-term operation of wind turbines, due to environmental factors and equipment aging, health reliability each component will gradually decline, leading failure. To assess status timely grasp subsequent changes development trends, it is necessary extract degradation characteristics, including time domain, frequency time-frequency domain characteristics. These characteristics can reflect operating equipment, help build indicator curves, evaluate high-speed shaft bearings turbines. Selecting reasonable an important prerequisite for constructing a index curve, using evaluation indicators construct comprehensive function screen The feature fusion method based on self-organizing mapping network used fuse multiple selected features into curve that bearing process. Finally, quantitative analysis performed scientifically bearings. Bearings are one key components Based constructed in this article, appropriate prediction model predict trend A effective trends turbine great practical significance formulating scientific maintenance measures farms. work article be divided following four parts: (1) Extracting vibration signals turbines; (2) Comprehensive monotonicity, correlation, robustness constructs degenerate features; (3) Use network. integrates curve; (4) optimize BiLSTM hyperparameters through Bayesian establish BO-BiLSTM achieve more accurate trend.
