An efficient method of wave processes in transmission line simulation using discrete models

A new method of wave processes in the systems of transmission lines (TL) simulation is proposed. The method is based on using discrete macro-models of lines and loads. Some theorems have been proved, which make the process of calculation of the discrete macro-models equivalent parameters and voltage and current distribution along the line much faster as compared to the solution of this problem by common integration of the system of differential equations. A method permitting to use the models, described by the frequency responses, in the time domain is offered. Other methods of solving such problems do not permit to take simultaneously into account both experimental frequency responses and nonlinear elements. The estimation of an error of the offered methods is presented. An application of the method is illustrated by the examples
