On-Board Energy Storage and Another Technological Solutions for Catenary Free Light Trains and Trams

Abstract: Nowadays, the use of energy storage combined with the regenerative braking systems of the trains can be already considered a conventional solution in railway systems. Such was the case that some manufacturers are using these kind of on-board accumulation systems to avoid the use overhead line equipment and to reduce the visual impact offering catenary free solutions. There exist other solutions for creating catenary free systems, like the ones based in third rail technologies (standard, controlled or inductive), but none of them are a good option for recovering the regenerated braking energy. In this webinar we will skim through all of these technologies describing their main features, drawbacks and benefits in terms of costs, operation, safety, reliability and efficiency.

Why the More and All Electric Aircraft Needs Power Electronics
New Day/Time - Thursday, September 21, 2017 - 10:00am ET - 11:00am ET
Presenter: Patrick Wheeler
University of Nottingham
Abstract: There has recently been a major change in the design of aircraft. Electrical systems are being used in applications which have traditionally been powered by hydraulic or pneumatic sources. The Boeing 787 and the Airbus A380 both have significantly larger electrical systems than any previous aircraft. The most important enabling technology for the More Electric Aircraft is been power electronics. Without power conversion none of the benefits of this technology would be possible. However, aerospace applications present some challenging conditions for power electronics and there are still a number of areas where improvements must be made in terms of the weight, volume, cost and reliability of systems. This presentation will introduce the More Electric Aircraft concept and investigate the potential benefits of the technology before considering the challenges our community will have to meet to make the concept of Electric Propulsion of large aircraft possible. The talk will be illustrated with a selection of case studies of systems that have been developed at the University of Nottingham, UK.
