Expert Systems with Applications, 12(1), 37-52, 1997



This paper presents short, a knowledge-based system for fault diagnosis in power transmission networks. Differently from previous approaches to this very complex diagnostic problem, short includes a knowledge representation formalism, named plot, capable of taking into account temporal aspects of component behavior, and solves the diagnostic problem as an instance of a more general class of temporal reasoning problems, called history reconstruction. Both plot formalism and the history reconstruction method are illustrated in the paper through an application example. short has been tested on both simulated and real cases of faults in an Italian regional transmission network, showing very good diagnostic capabilities.
