Siemens presents new technology for converter stations

In Munich today, Siemens will present its “full bridge technology,” which will be used in the latest generation of converter stations.
In October, Siemens was already awarded a contract worth €900 million to build two converter stations for the ULTRANET direct-current project. Transmission system operators Amprion and TransnetBW will implement this, the first of three planned high-voltage direct current transmission (HVDC) links between northern and southern Germany – an important milestone for the country’s transition to a new energy mix. At the start and end of the links, the converters, with a transmission capacity of 2,000 megawatts (MW), will convert electricity from direct current (DC) to alternating current (AC) and back again. The use of the full bridge technology makes it possible to resolve faults in the DC sections quickly and flexibly with no need to switch the system off. It also stabilizes the AC grid at the same time. ….
