A model for the study of fast transients on a D-C distribution system

Abstract

Fast voltage transients have been found capable of disrupting the operation of a proposed solid-state, ac-dc inverter system. A method is proposed for studying the propagation of such transients in an involved d-c power distribution system connected to such an inverter. The use of computer simulation of the system is proposed and detailed. Mathematical equivalents of various circuit elements are developed, and signal flow graphs are used to write the system's equations in a form adapted to the computer. Use of this method is shown to allow a large number of system locations to be chosen as inputs or as points of measurement, even when the simulation is programmed for a digital computer.
