In a major technological leap towards modernisation of Indian Railways’ existing fleet of conventional DC Traction Motor driven Electric Locomotives, Bharat Heavy Electricals Limited (BHEL) has successfully developed a Regenerative System for retro-fitment in these locos to make them energy efficient.
Following the successful development, Indian Railways has placed an order on BHEL for 25 nos. Broad Gauge 5000 HP AC Electric Locomotives of type WAG-7 with regenerative feature.
BHEL is the first to develop such a system for these locomotives. The system has the unique feature of utilising the kinetic energy of the train while in braking mode, which is re-converted into electrical energy and is fed back to the electric grid through OHE lines.
Earlier this energy was getting wasted in Dynamic Braking Resisters (DBRs) of locomotives in the form of heat. Read More
