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。
This paper presents a new method to simulate the fault diagnosis of large networks. The method first determines the faulty sub-network, and then further accurately locates and determines the faulty components. The established fault diagnosis equation has low non-linearity and regular Jacobian matrix, and greatly reduces the computational cost after the test. It is suitable for the fault diagnosis of linear and nonlinear large networks.
