摘　　要：建立人工神经网络BP算法 ,利用计算运行方式的变化改进传统的电力输电线系统的保护措施 ,可以实时跟踪故障点并同步实施控制。利用人工神经网络技术的快速性、自适应性和容错性 ,在一个周期内准确地定位区内、区外故障点 ,实现对输电线的速断保护。On the basis of BP model of multi-layer feedforward Neural Network is presented,the functions to determine and locatethe faults within or outside the protection zone of a transmission line.The three-phase fault and the single-phase grounding fault show that the fault can be exactly located and indicated by ANN within one period.It verifies this method is practical.
