- Abstract
In traction power supply systems (TPSS) extreme modes occur in emergency situations with extreme electromagnetic fields (EMF). Short circuit (SC) is one of the extreme modes that lead to considerable current flows in catenary wires with significant growth of magnetic field strengths. SC modes duration is rather small, since they are, as a rule, removed by relay protection rather promptly. Therefore, taking into account EMF effect on personnel during SC short-time modes is inexpedient. However, due to higher values of magnetic field strength, in wires of adjacent disconnected power and communication lines significant induced voltage can emerge, whose even short-time affecting personnel and telecommunications low-voltage equipment can be extremely negative. Procedure of EMF modeling and modeling results are presented in the article. EMF modeling was performed using methods and means for determining modes in traction power supply systems and EMF in phase coordinates developed in Irkutsk State Transport University. The main advantage of the approach offered is the systematic description of extreme modes, where traction network is considered inseparably connected with complex external power supply system.
