Development of a regenerative 3KV dc traction substation with active power filter capability

Author(s): L.O. Borchard, H.J. Beukes & J.H.R. Enslin

Abstract:
An active dc traction substation based on new solid-state technology is proposed. This technology enables the more efficient use of regenerated energy.

The system is not only able to inject the excess energy back into the ac supply, but it is also capable of working as an active power filter during normal traction load conditions.

At present, the excess regenerated dc energy is simply dissipated into resistor banks.

A second concern is the harmonic distortion caused by the traction rectifiers.

A 200- kVA-prototype converter has been developed and tested jointly by the University of Stellenbosch and Spoornet in a Traction Substation at Wolseley in South Africa.
