Rail engine will generate electricity on braking, BHEL develops regenerative braking system

Bharat Heavy Electricals Limited (BHEL) has developed innovative technology in the ‘WAG-7’ engine used by the Railways in an abundance number, under which electricity will be generated from the energy generated on the brake, which will return the feed back overhead line Will be done. On successful completion of this experiment, the first new technology-equipped engine was dedicated to the railway on Friday. 

WAG-7 engines of Railways are operated on DC motor. There is a lot of energy coming out during the dynamic braking, which gets wasted in the form of heat. To save this energy, BHEL has developed Regenerative Breaking System (regenerative braking system). Under this, the DC Traction motors engaged in the engine start working like a generator on the brake. It works in engines running at 15 to 100 kmph. According to the speed of the engine, each braking produces 30 to 50 kW of energy. Arrangements have been made to send the energy produced in the newly developed system back to the OHE line.

BHEL Chairman and Managing Director Atul Sobti said that this is the first engine of the country equipped with regenerative breaking system. This will save the power of the railway. This system has been developed by BHEL under its ‘Make in India’ initiative. On Friday, the engine was flagged off with the Regenerative Breaking System in the event organized at BHEL’s Jhansi unit. On this occasion, the Member of Railway Board (Traction) Ghanshyam Singh was specially present.
