Simulation of DC power distribution systems

Abstract

Direct current (DC) power distribution systems have been extensively used in nuclear power plants and transit systems. The major concern of DC system studies is the voltage and voltage drop at load buses. A Newton-Raphson method based DC load flow algorithm and a DC system simulation package have been developed and reported in this paper. DC generators, batteries, AC/DC rectifier converters and constant power, constant current, constant resistance loads can be considered in the simulation. Time-varying and moving loads can also be simulated.<>
