Abstract
The stray current generated by urban rail transit has become one of the major factors in the DC bias phenomenon of the main transformer of urban power grid. The electromagnetic field finite element method is used to theoretically calculate and analysed the geoelectric field of metro stray current. According to the mathematical model, the ANSYS finite element software is used to simulated and analysed the current under different stray currents. The results show that with the value of traction current increases, the stray current flowing into the ground increases, and the strength of the formed electric field increases.
