摘　　要：介绍了用人工神经网络实现输电线速断保护区内区外动作情况的判断和定位的功能,并通过对单相接地故障和三相故障的EMTP仿真测试发现,用神经网络可以在一个周期以内准确地显示和定位故障,证明了该方法的切实可行性。An ANN(Artificial Neural Network)is presented,which has the functions to determine and locate the faults within or outside the protection zone of a transmission line.The EMTP simulative tests for single-phase grounding fault and three-phase fault show that the fault can be exactly located and indicated by ANN within one period.It verifies this method is practical.
