本文基于多激励向量节点电压测量,提出了一个新的线性电阻网络的诊断方法。该方法是通过增加某些冗余变量,使得高次非线性诊断方程降为二次非线性方程。这对于扩大诊断方程的收敛域,降低迭代次数很有意义。本文还提出了几个元件参数可解性方面的定理,由此,我们可以选择适当的可测节点及激励向量。 In this paper, based on multi-excitation vector node voltage measurement, a new diagnosis method of linear resistor network is proposed. The method reduces the high-order nonlinear diagnostic equation to quadratic nonlinear equation by adding some redundant variables. This is meaningful for expanding the convergence domain of diagnostic equation and reducing the number of iterations. In this paper, some theorems about the solvability of several component parameters are also proposed. From this, we can choose appropriate measurable nodes and excitation vectors.
