PSI Awarded Major Contract by Swiss Federal Railway SBB

New network control system for a secure railway electrical supply

Berlin, Bern, 28 June 2010 – PSI AG has been awarded the contract to provide the Swiss federal railway SBB with an energy management system (EMS) and a traction current control system (TCCS). The basis of both systems is the PSIcontrol technology from PSI. The EMS is planned to go into operation in early 2013, the TCCS by October 2013. The existing systems will have reached the end of their economic lifespan at that time. The new systems are necessary to support the secure supply of electricity for the Swiss railway in the future. The project volume awarded to PSI is about 10 million Euros.

The new energy management system (EMS) regulates, optimises and monitors the energy production and transmission on its path from the power plant to the feed-in to the overhead line system. The traction current control system (TCCS) controls and monitors the overhead line system along the railway lines.

With the introduction of the new EMS and TCCS systems, their system architecture will also be harmonised. The operators will then have a modern training system. In addition, the alarm and fault management will also be aligned with the new company requirements. With the TCCS, the prerequisites for the integration of the previously three circuit systems into the new SBB control centres will be established. The systems will be realised as completely redundant, each distributed to several sites. There will be extensive interfaces to the SBB information technology.

PSI was able to win the SBB contract over major international companies on the basis of the evaluation by means of an extensive list of criteria. Following Germany and Sweden, Switzerland is the third European country that will use the PSI traction current control system.

PSI AG develops and integrates complete solutions, on the basis of its own software products, for the management of energy networks (electricity, gas, oil, heat, water), cross-company production management (metals, automotive, mechanical and plant engineering, mining, logistics) and infrastructure management for telecommunications, transport and safety. PSI was founded in 1969 and employs 1,400 persons in the group.
