Summary

Machine-generated summary

Deutsche Bahn is planning the renewal of its 16.7 Hz substation at the Cologne converter plant and intends to have the generator transformer Uk3 (16.7 Hz, 33.3 MVA, ABB) removed, transported away and subjected to an external factory overhaul. The buyer is Deutsche Bahn and the place of performance is Cologne, Germany. The tender concerns the retrofit of this transformer, which forms part of the frequency-converting network coupling units that link the public 50 Hz three-phase grid with the single-phase 16.7 Hz railway power supply.

Description

Die Deutsche Bahn betreibt in mehreren zentralen Umformerwerken frequenzelastische Netzkupplungsumformer bzw. Bahnstromumformer, die das öffentliche dreiphasige 50Hz-Stromnetz der allgemeinen Landesversorgung mit dem einphasigen 16,7Hz-Bahnstromnetz verbinden. Die frequenzelastischen Netzkupplungsumformer bestehen hauptsächlich aus zwei miteinander starr gekoppelten rotierenden elektrischen Maschinen - einem doppeltgespeisten Drehstrom-Asynchronmotor (50Hz) mit einer GTO-Leistungsregelung und einem Einphasen-Synchrongenerator mit Gleichstromerregung. Die Leistung aus dem öffentlichen 50Hz Drehstromnetz wird mittels eines 50Hz-dreiphasen-Transformators von 110kV auf die Betriebsspannung/Maschinenspannung (hier 10,5kV) der Asynchronmaschine herunter und durch einen Einphasen 16,7Hz-einphasen-Transformator auf 110kV hochgespannt. Im Zuge der geplanten Unterwerkserneuerung (16,7 Hz) im Umformerwerk Köln soll der Transformator Uk3 (16,7Hz, 33,3 MVA, ABB) abtransportiert und einer externen Werksrevision unterzogen werden.
