Railway applications - Three-phase train line voltage characteristics; German version EN 50533:2011/A1:2016

Overview
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 to - locomotive hauled (or pushed) passenger trains, - electric multiple units, - diesel electric multiple units. The three-phase voltage characteristics depend on the performances of the auxiliary converters which supply the train line but also on the AC load characteristics 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 taken 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 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 (that is, 3 AC motors, converters, filters, transformers, etcetera) connected to the grid. Some specific 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. This European Standard may apply to other rolling stock types (for example, light rail vehicles, tramways, metros, etcetera) if they are not in the scope of another specific standard. In this amendment to the standard, Annex ZZ (informative) has been added. The responsible committee is Subcommittee UK 351.1 "Fahrzeuge" ("Rolling stock") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
