Bharat Heavy Electricals (BHEL) has received an order from Indian Railways for 25 nos Broad Gauge 5000 HP AC Electric Locomotives of type WAG-7 with regenerative feature. The company has successfully developed a Regenerative System for retro-fitment in locos to make them energy efficient.
The company 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.
BHEL is India’s largest engineering and manufacturing company of its kind. It is a power plant equipment manufacturer and operates as an engineering and manufacturing company.
