  Traction power systems reliability concepts Sagareli, S. Rail Conference, 2004. Proceedings of the 2004 ASME/IEEE Joint Volume , Issue , 6-8 April 2004 Page(s): 35 - 39 Digital Object Identifier 10.1109/RRCON.2004.1300898 ... Summary: Reliability of a traction power system may be defined as its ability to continuously supply electrical power of adequate quality during sudden disturbances such as a short circuit or loss of system elements, while operating with a normal scheme configuration, or during scheduled maintenance and repairs, without causing safety hazards, train delays or public nuisance. While the utility power systems' reliability may be expressed in outage minutes per year (or any other time period), which is calculated as a ratio of customers' electrical energy deprivation to system's total power capacity, for a traction power systems' reliability evaluation, minutes of train delays caused by power interruption or relative values such as delay minutes per passenger-mile may be   [More...] [Less...]

  Welcome to IEEE Xplore 2.0: Electric railway traction. VI. Electromagnetic compatibilitydisturbance-sources and equipment susceptibility 

  http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=581216

  Abstract The railway traction environment contains many noise sources and receivers, and is considered to be EMI unfriendly because of the mixing of power, information and communications signals in space, ... time and frequency. Railway EMC has received much attention for 30 years following the development of converter-fed traction drives and computerised signalling systems. This article covers systems issues including the fundamentals of electromagnetic coupling, disturbance noise sources and receiver susceptibility. The article discusses EM noise sources in traction systems including: rectifier and transformer substations; track and traction line; vehicles and drives; radiative emissions (RFI); and signalling equipment. The article then discusses track and equipment susceptibility to EMI including: track and traction line impedance; traction drive impedance; track signalling system impedance; and track circuit receivers   [More...] [Less...]
