This paper describes a fault diagnostic system using a task-specific shell, MELDASH, and results that confirm its effectiveness. MELDASH (_??_itsubishi _??_ectric _??_iagnostic Application-specific expert system _??_ell) is a task-specific shell that reflects and makes use of the nature of model-based diagnosis. It is developed to overcome the drawbacks of methods that depend on operator knowledge. A high-performance fault diagnostic system is constructed simply by adding an application model to MELDASH. A prototype system is verified by connecting it to an operator training simulator. It is able to make a proper diagnosis in 79 difficult fault cases.
Verification results shows that the prototype system has sufficient accuracy. We confirm the effectiveness of this fault diagnostic method for future energy management systems.
