In a major technological leap towards modernisation of Indian Railways’ existing fleet of conventional DC Traction Motor driven Electric Locomotives, Bharat Heavy Electricals (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.
A pioneer in the transportation sector, BHEL has been working very closely with Indian Railways for the last six decades to meet their requirement of electric propulsion equipment for rolling stock and mainline electric locomotives. BHEL has already supplied 20 nos. 6000 HP WAG-9H Electric Locomotives last year and 10 more locomotives will be supplied this year. The company has augmented its capability to manufacture and supply around 100 locomotives per annum.
