Tuesday 2 September

8h20 – 9h00 : Opening session

Hubert Curien, President of the French Academy of Science:
“Science, Technology and Society: a modern triangle”
Session chairpersons B. de Fornel, INPT-ENSEEIHT-LEEI and R. Bassett, Alstom

9h00 – 9h40: Keynote 1

Mr Dominique Van den Bossche, Airbus Industrie, France
“More Electric” Control Surface Actuation; A Standard for the Next Generation of Transport Aircraft”
Session chairpersons B. de Fornel, INPT-ENSEEIHT-LEEI and R. Bassett, Alstom

For a long time the control surfaces of transport airplanes above a certain weight have been hydraulically powered. The most recent generation of in-service commercial transports is showing generalization of the electrical signaling of the hydraulic flight control actuators, known as Fly By Wire systems. The very new aircraft generation, presently under development, now features a mixed flight control actuation power source distribution, associating electrically powered actuators with conventional FBW hydraulic servocontrols.
The intent of this paper is to highlight the drivers for this evolution, to discuss the presently selected electrical actuator technology and the future of this “More Electric” configuration.

Wednesday 3 September

8h20 – 9h00: Keynote 2

Pierre Lego, Vice President Component, Alstom Transport
“Power Converters for traction application”
Session chairpersons: D. Stephani, SiCED and B. Anderson, Alstom

The drives for traction in railway application have some specificities which impact strongly the design. At traditional requirements as long life time, high reliability, severe environment, high performances and low Life Cycle Cost , we must now add emerging requirements as: increased performances , reduced weight, volume, and energy consumption , reduced impact on environment in use, when building and recycling .
The answer to these new questions can be given by technological evolutions in several areas:
- Power integration, to decrease weight, volume , costs;
- Autonomy with hybrid drives, to reduce various kinds of pollution, chemical, electric, EMI, visual, and to improve comfort and service;
- Medium frequency line transformers , to save energy ,volume and weight;
- Wide band gap components , to save weight and volume and to simplify architectures;
- New traction machines to save weight ,volume , energy and to reduce acoustic pollution .
In these areas ,economical and technical comparison will be given and prototypes will be described .

9h00 – 9h40: Keynote 3

Daniel Birfet, Vice President Technology, Alstom T&D
“Power Electronics in Transmission and Distribution Applications Today and in the Future"
Session chairpersons: D. Stephani, SiCED and B. Anderson, Alstom

Today power electronic solutions are used to solve problems with larger interconnected networks, and interconnections between adjacent networks, which may be very weak. All uses thyristors. These components, their applications and the reasons for their use will be briefly described in the address.

Today there is increasing pressure on ac networks, due to:

• De-regulation/ competition
• Unbundling/ Separation of Transmission/Distribution from Generation
• The need to provide access to the network for new players, e.g. merchant transmission or generation providers and traders
• Rapid load growth in third world countries or regions
• Environmental issues, including CO2, visual, EMF,
• The difficulty in getting permission for new overhead lines,or even pressure to remove existing lines
• Increased interest in the use of renewable energy sources

These pressures as wells as evolutions in power electronic device technology have led to a new generation of power electronic based T&D solutions, based around voltage sourced converters as well as a number of hybrid solutions, mixing conventional line-commutated and voltage sourced converters. These new systems, their applications and the reasons for their use will be briefly described. The technology developments, which will result in a dramatic growth in these new systems will be outlined. The address will conclude with the description of our view of the future Transmission and Distribution network, where power electronic systems are used extensively. In this vision every ampere that reaches the Consumer will at some stage have gone through a power electronics device.

Thursday 4 September

8h20 – 9h00 : Closing session

Session chairpersons B. de Fornel, INPT-ENSEEIHT-LEEI and R. Bassett, Alstom

9h00 – 9h40: Keynote 4:

Lars Gertmar, ABB, Corporate Research, Västerås, Sweden and Dep. of Industrial Electrical Engineering and Automation LTH/IEA, Lund University, Sweden
“Power Electronics and Wind Power”
Session chairpersons T. Undeland, NTNU, Norway and M. Jufer, EPFL, Switzerland

Renewable energy facilities will constitute a major contribution to electrical power in the future. The wind turbine will, together with biomass, form the major renewables parts up to year 2030 including erection of offshore wind farms. The wind is a non-storable energy source, whose electric energy needs priming into interchangeable energy to be competitive for large-scale power generation. An essential task is then to make wind power as commercially valuable and fungible as electric power produced by traditional, dispatched plants such as fossil fuel power plants, hydroelectric plants, nuclear plants and the like. Power electronics is an essential candidate in the remedies of priming wind power. Another candidate is automation starting in the towers and ending in load management. Power electronics and automation must both be cost-effective and reliable. Power electronic hardware must be common but in moderation because losses and investments must be paid back: by better trading on the power exchange, by availability, by reduced mechanical and/or civil engineering as well as by efficiency and reliability. An overview of wind power from different perspectives: collection & transmission (C&T), energy storage, R&D e.g. in EU and US, existing technology, future(s) business, etc. is comprised. EPE should be challenged to exploit wind power opportunities.
