Implementation of Fault Detection and Diagnosis System for Control Systems in Thermal Power Plants

摘要

A software-based system was developed for fault detection and diagnosis (FDD) of control systems in typical thermal power plants. For the large-scale industrial processes as thermal power plants, a three-level configuration to build a real-time FDD system is proposed. This configuration includes the component level, loop level and system level. Developed algorithms for each level and systematic approaches and steps to implement the overall diagnostic system are discussed. The developed system has been applied to a real-world thermal power plant to monitor its main control systems.
