Haar wavelet scale domain method for solving the transient response of dispersive transmission lines with nonlinear loads

摘要

A numerical technique based on Haar wavelets is used for solving transient problems of transmission lines. The approach of our method is to convert the original coupled par- tial differential equations, the transmission line equations or the telegrapher equations, to a system of ordinary matrix differential equations via Haar wavelets. Then, transient problems of trans- mission lines can be solved by matrix operations. Numerical ex- amples of homogeneous and dispersive lines, along with both lin- ear and nonlinear loads are verified.
