Eurocontrol. Cinq candidats pour le TGV de La Mecque. Siemens to install novel static frequency converters for Swedish. “Banverket”, the Swedish Rail Administration, has ordered six novel static frequency converters of the type Sitras SFC plus (Static Frequency Converter), each of which with a 17-Megawatt (MW) power output. In addition to the static frequency converters, the order includes instrumentation and control equipment, protection and control systems, buildings, and three-phase and single-phase switchgear. One converter will be installed in Eskilstuna and five others in Häggvik in order to supply power to the Greater Stockholm area.
They convert the normal three-phase current 50 hertz into single-phase traction power, which at 16.7 hertz is only one-third the frequency of three-phase current. What is special about the Sitras SFC plus solution is its multi-level converter concept. It has a modular structure consisting of a number of series-connected semiconductor components and capacitors which combine small voltage levels to produce the desired voltage.
