6 FAQs about [Energy storage solution for traction power supply system]

How does traction energy storage work?

Toshiba's Traction Energy Storage System efficiently stores surplus regenerative energy in the SCiB™ and discharges it to another accelerating train. TESS is installed with Toshiba's patented advance control system which allows flexible control of charge-discharge cycles in accordance to the battery's State-of-Charge (SOC).

Can a new energy storage traction power supply system improve regenerative braking energy utilisation?

To solve the negative sequence (NS) problem and enhance the regenerative braking energy (RBE) utilisation in an electrified railway, a novel energy storage traction power supply system (ESTPSS) is proposed in this study.

What is Toshiba traction energy storage system (TESS)?

Toshiba developed Traction Energy Storage System (TESS) with SCiB, a new energy saving solution with Toshiba's own battery technology of high quality.

How to integrate an energy storage device into ERS?

Currently, there are many ways of integrating an energy storage device into ERS, such as onboard system, RPC (railway static power conditioner) system and hybrid PV-based (photovoltaic-based) system.

Should traction power supply be neutral section?

One possible solution is to equip a co-phase traction power supply system with a suitable energy storage device on its DC side [ 17, 18 ]. Thus, the power quality can be considered and there is no need to use the neutral section device at the exit of the traction substation.

Which traction power supply system is used in electrified railways?

The single-phase 25 kV AC power supply system is widely used in electrified railways . Since the traction power supply system (TPSS) adopts a special three-phase to single-phase structure, it will cause three-phase voltage unbalance problem on the power grid.
