Abstract
In this paper, a stray current dynamic distribution model was established by Current Distribution, Electromagnetic Field, Grounding and Soil Structure Analysis (CDEGS) software. The rectangle cut-and-cover model is based on a practical construction in Shijiazhuang Metro Line 3. It showed the dynamic distribution of conductor-to-earth voltage and stray current under constant-current-strategy condition and target-speed-strategy condition. The traction current of the former one is changeless, but the later one should take into account passenger comfort and operational efficiency. The simulation results give several conclusions: Traction operation strategy and locomotive position have great impacts on the distribution of voltage and current. Through the analysis of various parameters, some efficient measures can be used to avoid the overvoltage condition and serious metal corrosion.
