The static system-tie frequency converter- a voltage source DC-link converter- located at Muldenstein/Germany is designed for feeding the railway network. This converter incorporated GTO thyristors on both the 3-phase 50 Hz and the 1-phase 16 2/3 Hz-side. Therefore, active power transfer is possible in both directions and additionally, reactive power is adjustable within converter current limits at both the 50 Hz and the 16 2/3 side. In order to minimize GTO switching losses fundamental wave switching is used at the individual GTO inverters. The closed control loop control structure of the converter is optimized for this fundamental wave operation principle at both continuous and transient operation. Fourier filters for signal aquisition, fundamental wave vector control and fundamental wave control sets are used for standard (continuous) operation. In case of GTO inverter peak current interactions with pulse blocking (e.g. caused by a line short circuit) transient control measures take command. The converter is capable of feeding the central railway network in a frequency-elastic mode, and the decentral railway line in a frequency-locked mode. tion
