| Fault diagnosis of boiler in power plant is an important tache of the power plant. It is active development direction to apply object oriented method and the technology of artificial intelligence in boiler fault diagnosis. Based on the existing theory and technology of fault diagnosis, firstly the likely fault condition was analyzed and systematic frame of boiler fault diagnosis was presented according to the boiler system's construction and function and fault traits, which were combined with boiler operation characteristic, the knowledge base and reasoning machine of the boiler operation fault diagnosis system were set up, at last, the system design was carried out using VC++. |
