Monitoring and diagnosis of coal mill systems are critical to the security operation of power plants. The traditional datadriven fault diagnosis methods often result in low fault recognition rate or even misjudgment due to the imbalance between fault data samples and normal data samples. In order to obtain massive fault sample data effectively, based on the analysis of primary air system ...
