摘要：The possibility of reducing the intensity of magnetic field created by a traction network of an alternating current electrified railroad is considered in the article. The electric field of such a traction network at a height of 1,8 m above is relatively small. In order to control the electromagnetic situation, 2x25 kV traction systems, sucking transformers with a return wire for the 25 kV system, amplifying and shielding wires of the traction network, passive screens on passenger platforms, optimization of train traffic schedules can be used. Fazonord software package developed at the Irkutsk State Transport University was used as a tool for the analysis of the above events. Using computer simulations, it was shown that the most effective methods for reducing the magnetic field strength are the use of screens on passenger platforms, optimal train schedules, and the use of “soft” train driving modes. The latter measure is able to reduce the peak magnetic field strength by about 25%.
