Development and implementation of a 1.5 MW inverter and active power filter system for the injection of regenerated energy in a Spoornet traction substation
Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2005.
Spoornet is one of South-Africa’s largest railway companies. It is very important to operate the railway system as cost effectively as possible. A large portion of the railway operates from 3 kV DC traction supplies. One method of cost saving is to utilise the regenerative braking mechanism of the electric trains.
