Driving a novel phasors formula for a Digital MHO Relay Algorithm for high voltage transmission line based on neural networks

A modified Digital MHO Relay Algorithm is present in this research. Phasors of voltage are used with no need to current signals. These phasors were combined with adaptive resonance theory (ART) neural network to eliminate the use of current phasors and then to current transformer. Artificial neural networks and fuzzy logic are used to achieve a high speed, more reliable and high accuracy fault detection for a high voltage transmission line. The neural network is trained to recognize faults on basis of a specific relay characteristic.
