The Thyrow converter station, south of Berlin, will enable Deutsche Bahn to convert electricity from the public three-phase power distribution grid, which operates at a frequency of 50Hz, to 16.7Hz and feed it into the rail power grid used to power trains and rail infrastructure.

The station comprises three compact 40MW static frequency converter modules.

These will use Hitachi Energy’s advanced power semiconductors, which will, according to the grid integration and power quality solutions supplier, provide a steady and reliable power supply at maximum availability and with minimal electrical losses.

The solution also includes a 30-year service contract and a digitalisation package. These will provide Deutsche Bahn with condition-based and reactive maintenance and data insights into the system status of the converter station over the life cycle.

“We are delighted that Deutsche Bahn has selected Hitachi Energy as partner of choice to secure the 16.7Hz power supply for their rail network,” stated Niklas Persson, managing director of Hitachi Energy’s grid integration business.

“This is an excellent example of how we collaborate together with customers and partners to accelerate the energy transition and advancing a sustainable energy future for all.”

The Greater Berlin rail network serves a metropolitan population of around 3.5 million people and is the hub for multiple high-speed train services to cities throughout Germany and neighbouring countries.

The order follows one awarded last year by Deutsche Bahn to Hitachi Energy for the 160MW Delitz converter station in the greater Halle/Leipzig area, which will, according to Hitachi Energy, be one of the most powerful converter stations for rail power worldwide.
