Power stations and frequency inverters
To supply trains with electricity, we generate traction current (16.7 Hz) in eight of our own power stations. Further sources include partner power stations and alternating current (50 Hz) from the public grid, which is transformed into traction current by seven frequency inverters. We also generate our own alternating current in two power stations.
Traction current projects
Traction current cables
The 110 kV traction current cable network of ÖBB-Infrastruktur is over 2,000 km long and is operated at a frequency of 16.7 Hertz.
Monitoring stations Control centres
The supply of traction current is controlled, regulated and monitored at the central monitoring station in Innsbruck. From here, the deployment of the power station and transformer machinery is centrally controlled according to the load situation in the rail network and optimised via online optimisation programmes.
Operational management of the energy supply networks for 15 kV traction current and the 50 Hz power supply is ensured at two energy monitoring stations.
