摘　　要： 在传统电流保护和距离保护原理的基础上 ,提出一种基于神经网络的自适应无通道的输电线路继电保护方法。设计了故障检测与选相子网络和定位子网络 ,通过对 2个子网络输出的综合判断 ,能够在保护范围内的故障实现全线速动 。 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, the protection was accelerated; if not, the protection was not acted.
