Advanced condition monitoring and fault diagnosis of turbo-alternators using an embedded expert system

The authors discuss a monitoring and diagnostic embedded expert system (MODEES) which forms part of a more general condition monitoring and fault diagnosis system (COMFAD). This is a rule based system with the ability to categorise power plant performance and recognise impending failure or dangerous trending, and the need for preventative maintenance or remedial action. COMFAD/MODEES is targeted at operator personnel who must decide within a short period if the power plant is fit for continued or prolonged service, and if not make a thoroughly reasoned 'guess' at what faults have occurred and how they can be remedied.<
