Online Fault Diagnosis Method for Photovoltaic Arrays Based on Temporal Feature Learning

To address the susceptibility of fault features to environmental fluctuations, insufficient use of temporal information in continuous operation, and class imbalance in online photovoltaic (PV) array fault diagnosis, a CNN-GRU-Attention-based method is proposed. First, relative-ratio features, an irradiance-normalized D...

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...

Low-Carbon Economic Optimization Method for Electric-Gas-Hydrogen Coupled Parks Based on Integrated Energy Flow-Carbon Flow Tracin

To address ambiguous carbon emission boundaries and accounting lags in multi-energy industrial parks, this paper proposes a low-carbon economic optimization method based on integrated electricity-gas-hydrogen energy-carbon flow tracking. A unified three-energy flow tracking matrix is constructed to reveal dynamic carbo...
