The Dedicated Freight Corridor (DFC) is an ambitious infrastructure development designed to enable the efficient movement of freight containers across the vast geography of the country. It is expected to relieve congestion on commuter routes and drive industrial growth and investments in these regions. ABB will play a key role by enhancing the system's reliability with an innovative power quality solution.

The Power Quality challenge

DFCCIL expects to transport up to 15,000 tons of load for long distances and will have a container capacity of 400 units per train, among the highest in the world. To cope with the volume, DFCCIL is pioneering the operation of double stack containers on electrified routes in India. The trains will be high-speed, with maximum speed varying between 75 kilometers per hour (kmph) to 100 kmph.

Such high speeds and variation of loads can affect power consumption patterns, creating significant voltage fluctuations and low power factor that cause power quality issues in the electrical railway traction systems. This could result in equipment malfunction and even downtime. Power quality issues can also spread through the supply grid, creating a domino effect of disturbances to other users. The potential risk of non-compliance to grid codes can also lead to financial penalties.
