An expert system approach for fault diagnosis in a sub-system of power plant

Abstract

This paper describes a simplified method for development of an expert system for fault diagnosis in the sub-system of a power plant. A most powerful approach for system reliability evaluation is fault tree or fault diagram analysis,which is basically a systematic analysis of different component failure events. This logic diagram is translated into an equivalent rule based expert system.Then,this has been used to determine the sub-system.Then,this has been used to determine the sub-system failure that has caused the breakdown of the plant. This knowledge based system for fault diagnosis has been implemented in C language under MS-DOS environment on an IBM PC-AT.
