State-run BHEL on Friday flagged off India’s first electric locomotive with a regenerative system for Indian Railways, it said. The regenerative technology helps avoid loss of heat energy when brakes are applied and feeds the energy back to the overhead power lines.
- A company statement said, BHEL has developed a state-of-the-art regeneration system through in-house R&D efforts for Indian Railways’ fleet of conventional electric locomotives.
- It added that the country’s first such regenerative 5,000 HP WAG-7 electric locomotive was flagged off from the company’s Jhansi plant.
- The idea of developing the energy-efficient regeneration system was mooted by Indian Railways and BHEL responded to it by successfully developing the technology in-house, giving an impetus to the ‘Make in India’ initiative.
- Currently, Indian Railways’ electric locomotives have a dynamic braking system where the energy generated during application of brakes gets wasted in the form of heat.
- BHEL has developed a system introducing the regenerative braking concept in these locomotives, that will feed the energy back to the overhead power lines.
- This will result in significant saving in energy consumption.
- BHEL is the first organisation to successfully demonstrate the concept of regenerative braking system for DC traction motor driven conventional electric locomotives.
