Application of artificial neural networks in network calculations

We describe radial basis functions as a special form of artificial neural n etworks and test whether they are applicable to power systems. In the appli cation to distance protection, the dividing and filtering capability are in the centre of interest. In modelling of equivalent circuits for external n etworks, primarily the static case is important. In the dynamic case the re search is started by using the E' model and the Park equations for generato r modelling.
