<br/><br/> A prototype knowledge based condition monitoring and diagnostic system has been  developed to act as an operational and diagnostic aid to operators of steam power plants. This  system enables abnormal and inefficient operating conditions such as high vibration, high value of  thermal expansion in steam turbines to be detected and diagnosed. Some special features of the  system include the simulation of the power plant process within a specified range of normal and  abno1mal conditions. The whole system is implemented on a P.C using object oriented  development environment and an expert system shell. The work investigates how knowledge can  efficiently be represented and administered using both an object oriented development  environment and an expert system shell. The knowledge acquired for the expert system has been  coded in the form of objects, rules and formula. Efforts have been made to make the  representation and reasoning structures and methods as generic as possible so that similar  systems for other power plants can be developed with minimal effort.
