Technical FAQs 4

How do ABB traction substations save energy?

ABB’s DC traction substations with energy storage capabilities allow energy to be recovered from braking trains that would otherwise be dissipated as heat through braking resistors. Storing this energy on the wayside is one way to prevent this energy waste.

What is a DC traction substation?

These pre-fabricated and transportable substations contain all main equipment, station auxiliaries and the station control system. Hitachi Energy offers a broad range of DC traction substations for all types of applications including urban transport systems, suburban and mainline railways.

What is a container substation?

An intelligent solution for obtaining direct current quickly and economically is provided by container substations. By integrating the equipment in a modular housing and undertaking rigorous testing off site, Siemens is able to supply fully built and tested modular traction power substations to a consistent and high level of quality.

Can a hybrid energy storage system smooth out DC traction network power fluctuations?

A hybrid energy storage system has also been reported aiming to smooth out DC traction network power fluctuations, due to moving trains. In this context, a variable gain K iterative learning control (K-ILC) is proposed to balance the DC regulated voltage characteristics and thus lead to optimal lifetime of the battery storage system.
