Title: Data-driven smart operation systems in process industry
Abstract:
Process monitoring and fault diagnosis based on data driven methods have attracted great attention from both academia and industry, but they are still facing serious challenges in industrial application. Simulated processes, i.e., Tennessee Eastman Process, are usually discussed in literature as benchmark cases, while they are relatively well defined and simplified compared with real industrial cases, which are far more diversified and impacted by random disturbance.
In this presentation, the conventional process monitoring and fault diagnosis methods are briefly introduced, followed by the challenges from industrial operation. Feature extraction is discussed based on cross correlation, auto correlation and spatial correlation. Monitoring strategy is addressed for multiple operation state based on historical data. Causal reasoning based on mutual information analysis is obtained for fault diagnosis. An on line monitoring system is then integrated with auto-data communication with DCS system and accessible to end users with different authorization levels.
