Abstract
Based on the traditional current relay protection and distance relay protection
a new principle of transmission lines relay protection using the theory of artificial neural network is proposed in this paper. The new principle is implemented based on two sub-neural networks. One of the sub-neural networks is for the fault detection and fault phase determination. The other is for the fault location. The resultant action of the protection is determined by the comprehensive judgment of the two sub-networks outputs. If the fault happened in the area of protection
