“黑箱”子网络的子网络转移阻抗矩阵的计算

The calculation of transfer-impedance matrix for black-box subnetwork

本文讨论了基于子网络CCCS模型的子网络转移阻抗的计算公式,它仅依赖于子网络端口伏安关系和子网络CCCS模型及子网络端口与撕裂端的拓朴结构参数,而与子网络内的结构和参数无关,因此,可以实现“黑箱”子网络的子网络转移阻抗的计算,对于完成“黑箱”子网络故障的诊断具有实际意义。

The calculation of transfer-impedance matrix on subnetwork CCCS model is discussed. This algorithm depends only on the characteristic of port AV and the topology relating to subnetwork CCCS model as well as the split port of network. The calculation is not affected by the topology and parameters inside subnetworks . Thus this method can be used in the deduction of subnetwork transfer-impedance matrix for black-box. Therefore, the proposed algorithm has practicalsignificance for fault diagnosis of black-box subnetworks.
