摘要

提出了一种具有非线性负载的有耗输电线路的稳定分析方法。仿真采用时间推进(TM)方法在时域内求解卷积方程。针对TM方法的后时不稳定性,提出了一种基于倒谱和z变换分析的TM方法。通过将其结果与使用(i)全波FDTD方法和(ii) CST Cable Studio获得的模拟结果进行比较,证明了所提出方法的效率。

Stable simulation of nonlinearly loaded lossy transmission lines with time marching approach
A stable method for the analysis of lossy transmission lines with nonlinear loads is presented. The simulation employs the time marching (TM) method for solving the convolution equations in the time domain. To cope with the late-time instability of the TM method, a novel approach based on the application of Z-transform analysis and cepstrum is presented. The efficiency of the proposed method is demonstrated by comparing its results with simulations obtained using (i) a full-wave FDTD approach, and (ii) CST Cable Studio.
