Digital Traveling-Wave Solutions I-Single-Phase Equivalents

Abstract

A method of analysis of complex traveling-wave problems has been developed and reduced to a practical program. The program, presently limited to single-phase equivalent systems, can accommodate complex terminations, loop systems, general input waveshapes, and multiple arrester operation. The method is capable of extension to nonlinear resistive elements and to 3-phase systems. Immediate areas of application include arrester separation problems, simple switching surge probelms, and solutions for system recovery voltages. Areas of possible future applications include problems involving distributed-constant lines with nonuniform (tapered) surge impedance and certain steady-state problems (e.g., rectifier networks) which are difficult to solve analytically.
