A model-based approach to fault localisation in power transmission networks

The basic idea of model-based diagnosis is to exploit knowledge about the structure and behaviour of the physical system to be diagnosed in order to identify diagnoses from discrepancies between observed and predicted behaviour. The authors describe the application of model-based diagnosis to the problem of fault localisation in power transmission networks. They also show that the resulting system, DPNet, has an extended competence w.r.t. rule-based approaches (treatment of unknown and multiple faults) while requiring less development effort because of the use of component libraries in the model-based approach
