This paper presents a new technique for the transient analysis of long lossy cables. The proposed model represents an improvement of the standard ladder network approximation of transmission lines for two reasons: First, the propagation delay time is preliminarily extracted so that the lossy phenomena are modeled as minimum delay lossy cable, and second, a model order reduction (MOR) is applied to the lossy line via the analytical calculation of poles and residues of the half-T ladder network approximating the delayless lossy cable. The combination of such two techniques allows us to achieve a significant reduction of the computational efforts in simulating long lossy cable while preserving the modeling accuracy. Numerical tests are performed that demonstrate the robustness and accuracy of the proposed method.

Abstract

This paper presents a new technique for the transient analysis of long lossy cables. The proposed model represents an improvement of the standard ladder network approximation of transmission lines for two reasons: First, the propagation delay time is preliminarily extracted so that the lossy phenomena are modeled as minimum delay lossy cable, and second, a model order reduction (MOR) is applied to the lossy line via the analytical calculation of poles and residues of the half-T ladder network approximating the delayless lossy cable. The combination of such two techniques allows us to achieve a significant reduction of the computational efforts in simulating long lossy cable while preserving the modeling accuracy. Numerical tests are performed that demonstrate the robustness and accuracy of the proposed method.
