Design of Drive System for Head-On-Generation Through Slip-Power Recovery in Passenger Electric Locomotives

Train Lighting and Air-Conditioning is an important aspect of Passenger Coaches and for Trains like the Shatabdi/Rajdhani/Durunto/Double-Deckers/Garib-Rath which run on the Indian Railways, the Power for the Lighting and Air-Conditioning Systems is generated from the Diesel Generator Cars attached on either ends of the Train. This is called End-On-Generation. The use of End-on-Generation which causes lot of noise and air pollution can be eliminated if the Power supply is derived from the Locomotive itself. The authors of this Research Paper intend to propose a Drive System for Traction in which Squirrel Cage Induction Motors will be replaced with Wound Rotor Induction Motor as Traction Motors with a low-Voltage Slip-Power on the Rotor side to Drive the Lighting and Air-Conditioning Loads of the Trailing Passenger Coaches which will be called Head-On-Generation.
