Abstract

In this paper, a generalized MTL (GMTL) model is developed for modeling of wide frequency transient response on busbars, cables and core-type transformer windings. Different from the traditional MTL model, the equations of the GMTL model are built in the cylindrical coordinate system besides rectangular coordinate system, where the per-unit-radian coefficient matrixes are calculated. Based on further discussion, it is found that GMTL model could be changed to MTL model where all lines have the same length as to the core-type transformer windings. Then, the generalized solution based on Time domain finite element (TDFE) is developed for the above MTL equations. It avoids Gibbs effect of the finite difference time domain (FDTD) method. The numerical results are in agreement on ones calculated by Bergeron's method and FDTD method.
