Abstract :
A new directional element for an on-line trained neuro-fuzzy network (NFN) numerical distance relay is developed. Numerical simulation studies are performed on a differential equation based transmission line model that includes the fault resistance and the remote-end infeed. The fault direction is identified based on the +/- sign of the estimated fault distance. The results obtained show fast estimation of distance to the fault with accurate fault direction assessment.
