28、(IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addi
29、tion to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interes
30、ted in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance wit
31、h conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested I
32、EC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for
33、 the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between
34、any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users s

41、2427 IEC:2007 INTRODUCTION This Standard defines a process to obtain the assurance that specific rolling stock operating on a specific route does not interfere with train detection systems installed on this route. Compatibility problems between train detection systems and rolling stock are a signifi
42、cant obstacle to cross-acceptance of rolling stock in Europe. Unfortunately it is not possible to establish general rules for the maximum levels of interference allowed valid for every country. This is due to the great diversity of rolling stock, power supply and return current systems, and train de
43、tection systems installed in Europe. This diversity leads to consideration of the problem of compatibility of rolling stock and train detection systems for specific routes to avoid unnecessarily restrictive specifications. Compatibility is determined by both physical and electromagnetic consideratio
44、ns. With regard to EMC, the need is not for general values for maximum levels of interference permitted, but for convenient methods by which to specify the level of interference allowed for operation on specific routes. Interference may be caused by rail currents, electromagnetic fields, differentia

Rail current transfer functions Electromagnetic field transfer functions Track circuit Others Wheel detector Feeder station IEC 1747/07 Figure 1 Sources of electromagnetic interference 62427 IEC:2007 7 In practice, the susceptibility of the system is de
46、termined by the sensitivity of individual components of the system, the application of the components, i.e. the configuration of the system. Therefore the problems concerning track circuits and axle counters or wheel detection systems will be considered separately. For determining the susceptibility
47、 of train detection systems, laboratory/simulation testing methods as well as methods to conduct tests on the “real railway” are proposed. Modelling enables worst-case conditions to be simulated. In addition, particular test sites are used because, from experience, they are known to provide the test
48、 evidence required. Then, taking account of the experience of the railways, it is possible to establish a general method for determining the susceptibility of train detection systems, described in this Standard. Before measuring the interference level on rolling stock, a sufficient knowledge of the
49、electric circuit diagram of the power equipment is required, e.g. switching frequencies of on-board static converters, type of regulation used for power converters, resonant frequency of each filter, operating limits under high and low supply voltages, downgraded modes of operation, etc. 8 62427 IEC:2007 RAILWAY APPLICATIONS COMPATIBILITY BETWEEN ROLLING STOCK AN
