Storage Batteries and Railway Power Stations

Capacity utilisation and performance at railway stations

As traffic levels increase on railways in Britain and elsewhere, improved understanding of the trade-offs between capacity provision/utilisation and service quality is increasingly important, as Infrastructure Managers and Railway Undertakings seek to maximise capacity provision without an unacceptable loss of service reliability and punctuality. This is particularly true of the stations and ju...

Power Supply-and-Demand Balancing Solution Using Distributed Storage Batteries

In order to resolve the issue of the power supply-and-demand balance that has been triggered by the increased use of renewable energies, the traditional supply-and-demand adjustment on the power supply side is already regarded as inadequate. The potential for a new supply-and-demand balancing mechanism considering the demand side is currently under active deliberation. The “demand response” (DR...

Modelling Interlocking Systems for Railway Stations

Improving Customer Proximity to Railway Stations

We consider problems of (new) station placement along (existing) railway tracks, so as to increase the number of users. We prove that, in spite of the NP-hardness for the general version, some interesting cases can be solved exactly by a suitable dynamic programming approach. For variants in which we also take into account existing connections between cities and railway tracks (streets, buses, ...

Energy-saving Technology for Railway Traction Systems Using Onboard Storage Batteries

Motomi Shimada Yoshihiro Miyaji Takashi Kaneko Keita Suzuki OVERVIEW: The first application for onboard storage batteries came with the commercialization of series hybrid drive systems that reduced the fuel consumption of diesel trains. Storage battery control has also been used for the absorption of regenerative electric power and to implement the regenerative brake with extended effective spe...
