Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2005. / Although regenerative braking has been in used in railway systems for a long time
already, the energy generated was dissipated in resistor banks. The rapid advances
in the power electronics field, accompanied by the development of faster and higher
power switching devices in recent years, now make it possible to convert the
regenerated electrical energy from DC to AC, which can then be injected into the
Eskom grid.
A 1.5 MW full scale prototype system was built, installed and tested in a Spoornet DC
traction substation. A seven level series-stacked converter topology was used along
with a specially designed injection transformer. The system was controlled by the
PEC 33 controller board, which was developed at the University of Stellenbosch. The
primary function of the system is to function as a regeneration converter and as a
secondary function act as an active power filter.
