Abstract: Electromagnetic transients in arbitrary single- or multiphase networks are solved by a nodal admittance matrix method. The formulation is based on the method of characteristics for distributed parameters and the trapezoidal rule of integration for lumped parameters. Optimally ordered triangular factorization with sparsity techniques is used in the solution. Examples and programming details illustrate the practicality of the method.

- 01 Nov 1967
TL;DR: The method of characteristics provides a simple analytic solution for the transient analysis of a uniform, lossless transmission line that is superior in both speed and accuracy to the familiar method of integrating the differential equations that describe a lumped LC model of the line.
