Abstract

Retention of Passenger and Freight Trains working on Electric Traction at Stations in the event of Grid Failures / Locomotive Failures cause inconvenience to passengers and delay in delivery of freight, thereby causing losses in revenue. As Traction is a high Power Application, delivery of Power of the order of 1600 kW per Traction Motor would also cause stresses in the Switching Devices in a 3-j Converter System. In order to overcome stress on Switches, a new Drive System using 5-j Inverter driven Permanent Magnet Synchronous Motor as Traction Motors that can run on both Electric and Diesel-Electric Traction is proposed by the authors in this research paper.
