| Abstract |
Today the transmitted power in a.c. railway networks increases due to the higher density and speed of
the trains. Therefore higher currents are flowing via the tracks and the earth causing problems with the
electromagnetic compatibility (EMC) and problems with the personnel safety. Both phenomena can be
significantly reduced by means of a new transmission scheme working with an active return
conductor. A conventional return conductor is installed near the catenary and connected with the track
at equidistant points. In every return conductor-track-loop an Unified Power Flow Controller (UPFC)
suppresses the track current. Simultaneously the earth current is drastically reduced. Besides
improving the EMC behaviour and the personnel safety the UPFC-stations can also be used for
stabilising the catenary-track-voltage in an a.c. railway system. |
