Development of a 413 MW railway power supply converter

In Datteln, West Germany, at the site of a new 1100 MW hard coal fired power plant world's largest railway power supply converter station will be built and will convert after completition and commissioning in 2011 up to 413 MW 50 Hz three-phase power into 16.7 Hz two-phase power for Germany´s 110 kV traction power system. The converter station exists of four converter blocks, which ensure n-1 redundancy due to their overload capability to absorb a failure of one converter block and provide maintenance under full load conditions. The power electronics design of the converter is based on reliable IGCT technology and offers an innovative mulit-level voltage sourced converter design to achieve grid code requirements without any line filters.
