When in operation, the 25 kV traction networks may encounter the contact wire short circuits to rails or ground. The short-circuit conditions cause high-intensity magnetic fields (EMFs), which, despite the short duration of exposure, can negatively affect electronic devices and lead to significant induced voltage on adjacent power lines. There can be two main types of emergency conditions in 25 kV traction networks: the contact wire short circuit to the rail, when the supports are grounded to the rail track; and the contact wire short circuit to the ground in sections with supports disconnected from the rails. A three-dimensional electromagnetic field near a metal support when a short-circuit current flows through it is characterized by a complex spatial structure, which significantly complicates the calculations of intensities. The paper discusses the results of computer modeling aimed at determining the EMF intensity in the described emergencies. The objects involved in modeling were represented by segments of thin wires to calculate the electric charge distribution and find out the EMF intensity. This approach is implemented in the Fazonord software. The modeling results have shown that EMF intensities near the support grow significantly; their levels decrease noticeably as one moves away from the support; and that the three-dimensional electromagnetic field under the considered emergency conditions has a complex spatial structure.

“…Electric power facilities generate electromagnetic fields (EMFs) of fundamental and higher harmonic frequencies [1,2], which are among the main factors that determine the electromagnetic safety conditions [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. High-intensity electromagnetic fields can generate interference causing malfunctioning of electrical and electronic devices and result in serious accidents when one operates at tripped power lines due to the impact of induced voltage on personnel.…”

The establishment of smart grids requires special attention to the safety of power industry facilities and the reduction in their negative impact on personnel and the environment. A significant factor of such an impact is the considerable intensities of electromagnetic field (EMF) generated by such facilities. In the context of power industry digitalization, the development of methods and tools for EMF digital simulation is needed to ensure the electromagnetic safety of the service personnel. Computer models designed to adequately determine the EMF generated by overhead power lines (OPL) can be implemented based on the methods and tools created to determine operating parameters of electric power systems in phase coordinates developed at Irkutsk State Transport University. The technique of electromagnetic safety analysis is implemented based on the proposed approach and has the following features: a systems approach, which is the possibility of simulating electromagnetic fields in terms of properties and characteristics of a complex electric power system; versatility, which allows simulating power lines and traction networks of various designs; appropriateness to the environment achieved by considering the profile of the underlying surface, underground utilities, and artificial structures of rail transport, such as galleries, bridges, and tunnels; comprehensiveness, which is provided by combining the computation of operating parameters and the determination of EMF intensities. The paper describes methods and algorithms developed to determine the intensities of electromagnetic fields generated by multi-conductor power lines at fundamental and higher harmonics frequencies. A technique for the EMF determination at the points of OPL orthogonal crossing is also presented.
