| Abstract: | This paper introduces metro DC power supply and the formation of stray current,derives stray current distribution patterns from the characteristics of this power system,draws the track-buried metal-earth resistance of the distribution of stray current.Through the use of Matlab programming,this paper makes a numerical analysis of the stray current distribution,and obtaines the mutual relations between stray current and each influencing factor. |
