An anomaly detection method for gas turbines in power plants using conditional variational autoencoder optimized with self-attention

An innovative anomaly detection (AD) framework designed for gas turbines (GTs) in power plants working under variable operating conditions (OCs) was proposed based on conditional variational autoencoder (CVAE) optimized with self-attention (SA) in this paper. Three key factors contribute to the mode...
