摘要
本文提出一种模拟大网络故障诊断的新方法。该方法首先判定故障子网络,然后再进一步对故障元件进行准确的定位和定值。所建立的故障诊断方程具有较低的非线性度及规则的雅可比矩阵,测试后计算量大大减少,适合于线性和非线性大网络的故障诊断。
A new approach to fault diagnosis of large analog networks is presented. The approach contains two steps. The first is to determine the faulty subnetworks, and the second to locate and compute the values of the faulty elements. The diagnosis equation established has lower degree of nonlinearity and regular Jacobian matrix form.By applying this approach, the amount of computation after test is greatly decreased, and it is applicable to large networks, linear or nonlinear.
