A HARMONIC ANALYSIS OF KOREAN ELECTRIC RAILWAY SYSTEM

초록

This paper deals with a modeling for the harmonic analysis on the Korean high-speed railway system using MATLAB 5.2 program. The proposed model is for harmonic analysis in the AC electric railway system including feeders, contact lines, rails and autotransformers. The system model is based on 8-port representation, which is an extension of 2-port network theory. The proposed model is developed by combining fundamental element models of the Korean high-speed railway system. This model is verified by comparing simulation with measurement regarding the amplification rate of harmonic currents and the total harmonic distortion(THD).
