Production Of Three-Phase Electric Locomotives Using IGBT Technology To Implement The HOG Scheme

Abstract

To alleviate noise and air pollution, the Indian Railways has implemented an environmentally friendly and energy efficient solution in passenger trains. The technology transforms locomotives and coaches, allowing them to be used in Head-On
Generation. The railways have created and improved converters for use in electric locomotives. Diesel generators can also be replaced by these converters. The converters allow locomotives to be converted to run-on head-on generation technology. There will
be no more power generator cars, which used to create a lot of noise and emit a lot of emissions. In place of two such generator cars, one standby quiet generator car will be deployed in the event of an emergency. LSLRD (LHB Second Luggage, Guard &Divyaang
Compartment) will take the place of the other vehicle. This LSLRD will also be able to convert power from the overhead supply so that it can be used throughout the train, as well as provide space for a luggage guard room and additional passengers. Self Generation (SG), in which the train has only a few air-conditioned coaches, and End on Generation (EOG), in which the train has all air-conditioned coaches, such as in the Rajdhani, Shatabdi, and Duronto trains, are the two most frequent systems now in operation. The Railway Board had issued instructions via letter No 95/elec(G)/114/13 Pt dtd. 25/10/07 for the implementation of the HOG scheme by producing three phase electric locos with IGBT technology and at least two 500 KVA hotel load converters on locos and one under-slung DA set in SLR for Rajdhani/Shatabdi trains. The purpose of this paper is to look at the existing use of locomotives in the IR system, the rolling stock generation technique, the HOG scheme, and the issues that come with implementing HOG on the IR network.
