| 摘 要： | 为了解决故障诊断中特征变化量在正常运行值两侧变化分别对应不同故障类型的问题,提出了一种扩展隶属函数结构,将传统的隶属度值域从[0, 1]扩展到[-1, 1].将此方法用于改进模糊神经网络诊断模型,可以有效减小模型复杂程度.通过输电线路故障选线仿真证实了该方法的有效性.

| Abstract: | In the fault diagnosis model,in order to deal with the problem that the variables varying around their normal values,with different side corresponding different fault type,an extended membership function is presented in this paper,which extends the value range of the normal membership function from to .This method can reduce the complexity of the fault diagnosis model.The diagnosis result of simulation of discriminating the faulted lines proves the validity of this method. |

| Keywords: | membership function fuzzy neural network transmission line discriminating the faulted lines |
