NEURAL NETWORK APPLICATIONS TO REAL-TIME AND OFF-LINE FAULT ANALYSIS

This paper is concerned with application of Neural Networks (NNs) to fault analysis for both the realtime applications such as protective relaying of transmission lines and the off-line applications such as postmortem study of fault events recorded with Digital Fault Recorders (DFRs). A supervised learning NN of the same type is utilized for both applications. It has been demonstrated that the NN approach reaches performance of the existing techniques in both application areas and yet shows some additional benefits.
