   Design and Supervision Strategies for Embedded Electrical Power Systems Equipped with Energy Storage Devices
By Christophe SAUDEMONT, Stefan BREBAN, Fabien MOLLET, Régis MEURET, Benoît ROBYNS [View]
[Download]

Abstract: To increase the energy efficiency of transport sector and to store the energy during braking operations will contribute to the reduction of the greenhouse effect. The choice, the design and the energy management of the storage system is an important problem because of weight and volume constraints. This paper aims to propose a design methodology of a hybrid storage and dissipation system connected to a DC network. The proposed approach integrates the supervisory of this hybrid system and the storage control. This paper focuses on the storage parameters and its interface. The proposed approach is validated with the help of experimental results.

   Laboratory Scale Prototype of a Power Electronic Transformer for Traction Applications
By Drazen DUJIC, Akos MESTER, Toufann CHAUDHURI, Antonio COCCIA, Francisco CANALES, Juergen STEINKE [View]
[Download]

Abstract: Combining modern high-power semiconductor devices with constantly improving magnetic materials opens up the possibility to replace bulky low-frequency transformers with a new medium voltage medium frequency conversion structure. While there are still challenges to be addressed related to these, so called power electronic transformers, a steadily increasing development effort is evident and considered in various contexts. Traction applications seem to be the first ones, where proliferation of these new power electronic converters, are expected. In this application field substantial weight and volume reduction could be achieved, providing additional functionality at the same time. In this paper experimental results obtained from a laboratory scale prototype of a power electronic transformer are presented, focusing primarily on the control system design and also considering specific traction requirements. This prototype was built to support full-size converter development.

   The Use of Real Time Digital Simulation and Hardware in the Loop to De-Risk Novel Control Algorithms
By Sean LODDICK, Ushe MUPAMBIREYI, Campbell BOOTH, Andrew ROSCOE, Steven BLAIR, Xinyao LI, Jim WATSON, Kevin DAFFEY [View]
[Download]

Abstract: Low power demonstrators are commonly used to validate novel control algorithms. However, the response of the demonstrator to network transients and faults is often unexplored. The importance of this work has, in the past, justified facilities such as the T45 Shore Integration Test Facility (SITF) at the Electric Ship Technology Demonstrator (ESTD). This paper presents the use of real time digital simulation and hardware in the loop to de-risk an innovative control algorithm with respect to network transients and faults. A novel feature of the study is the modelling of events at the power electronics level (time steps of circa 2 µs) and the system level (time steps of circa 50 µs).
