| Abstract: |
| A real-time intelligent fault diagnosis system for power plant is designed with the help of the simulation system based on virtual DCS(Distributed Control System),which provides both the fault data and the OPC(OLE for Process Control) server. The relationship between real DCS-based and virtual DCS-based simulation systems is discussed,as well as its data interface to fault diagnosis system and the construction of knowledge database in expert system. The test results indicate that the fault diagnosis system designed with the virtual DCS-based simulation system realizes the real-time fault diagnosis and accident prediction of the power plant. |
