24、functions. EN 50547 1)Railway applications Batteries for rail vehicles Standardized batteries for rail vehicles and charging characteristics. The three-phase voltage characteristics depend on the performances of the auxiliary converters which supply the train line but also on the AC load characteris
25、tics connected to this train line. In railway applications the available auxiliary power of the train line is generally slightly higher than the power needed by the consumer loads, consequently tight interactions between the auxiliary power converter system and the loads are common and have to be ta
26、ken into consideration for a proper operation at train system level. The main objective followed by this European Standard is to define as much as possible the static characteristics and the dynamic behaviour of the on-board three-phase supply network to assure the best electrical compatibility with
27、 the AC loads connected to. This European Standard is a guideline for specifying and designing the different parts of the auxiliary power supply system namely the different auxiliary converters and the AC loads (i.e. 3 AC motors, converters, filters, transformers, etc.) connected to the grid. Some s
28、pecific characteristics of the train line voltage may impact the reliability and the life time of the AC loads if they are not taken into consideration during the design phase of the AC loads. The three-phase train line voltages are never perfectly balanced and pure sinusoidal waveform voltages, as
29、examples: 1) Under development. BS EN 50533:2011EN 50533:2011 6 o the switching of the semi-conductors within the static auxiliary converters may generate voltage harmonics and dU/dt steps on the train line; o the line-to-earth voltage level can vary with the auxiliary supply architecture and the ty
30、pe of faults in the train line; o a common mode voltage can appear to the star point of the 3 AC loads; o the non linear AC loads can be a source of current harmonics, those currents combined with the train line impedance create voltage harmonics too (mainly the input rectifiers of certain AC loads)
31、. In summary: o voltage harmonics can generate noise, additional Joule or iron losses in auxiliary motors and transformers; o high dU/dt and the common mode voltage are at the origin of motor bearing currents which may lead to a reduced bearing lifetime; o voltage spikes and overvoltages may cause a

BS EN 50533:2011 7 EN 50533:2011 1 Scope This European Standard describes the electrical characteristics of the three-phase train line which delivers the electrical energy from the auxiliary power converter system to the auxiliary loads. It applies
33、 to: o locomotive hauled passenger trains, o electric multiple units, o diesel electric multiple units. This European Standard may apply to other rolling stock types (e.g. light rail vehicles, tramways, metros, etc.) if they are not in the scope of another specific standard. 2 Normative references T
