Early Warning Method for Gas Turbine Bearing Vibration State Based on TCN-Transformer Prediction and PCA Statistical Monitoring

An early-warning method combining TCN-Transformer prediction and PCA statistical monitoring is proposed for gas turbine bearings with weak early-fault features and noise interference. Multi-point vibration signals are denoised using median filtering and Savitzky-Golay smoothing. A TCN-Transformer model predicts normal...
