Security of supply via power cable in the Gotthard Tunnel , Schweizerische Bundesbahnen (SBB) Infrastruktur Energie, Zollikofen, Switzerland

FIT-Projekt: GIS-Systemerneuerung

SBB contracted Fichtner IT Consulting to prepare a study, on the basis of various preliminary investigations, on ensuring security of power supply by installing a 132 kV cable in the Gotthard Basis Tunnel. Following detailed analysis of these investigations and preparation of models by our consultants for technical analyses and studies, risks are assessed with the focus on conversion and extension of relevant systems and network sections. Combinations of failures in line with operational experience, aging assumptions and other external factors are taken as a basis. Then security of supply is assessed on the basis of risk classes, and supply/consumer structures evaluated with their impacts on cable availability or non-availability.


The study concludes with risk analysis and recommendations for minimization of risks and their impacts.
