Abstract: Electrified railways and overhead railway continuous power line are usually laid in parallel, with short horizontal distances and long parallel distances, which makes overhead railway continuous power line susceptible to interference from the electromagnetic field of traction power supply systems. The resulting induced voltages and induced currents pose a major threat to the safety of maintenance personnel and the stable operation of power supply facilities. In this paper, the electromagnetic coupling mechanism of the overhead railway continuous power line is analyzed, and the induction simulation model of railway continuous power line is built by using CDEGS simulation software. The correctness and effectiveness of the model are verified by combining the field measured data, and the influencing factors and influencing laws of the induced electricity of the overhead railway continuous power line are studied, aiming to provide a reference for the safety protection of induced electricity in railway continuous power line.
