非线性电阻网络的支路故障诊断

Branch-fault Diagnosis for Nonlinear Resistance Network

用Ｋ故障法与元件参数解法相结合的办法进行了非线性网络的直流故障诊断。讨论了该法的可诊断性及提高可诊断性的方法，并通过实例说明了这种方法的有效性。

: This paper presents a method in which the effect of nonlinear elements in Trick fault equations is screened out by choosing the excitation vectors of accessible nodes and adjoint networks properly. Thus the multiple fault diagnosis can first be carried out in the linear parts and the results obtained are put back in the Trick fault equations in order to obtain the changes in the nonlinear parts. Discussion and analysis are presented in this paper on the network diagnosability as well as the screenable conditions of nonlinear elements. The methods to improve diagnosability and screenable conditions are also given.
