EPE'97 : KEYNOTE SPEECHES ------------------------------------------------------------------------ Opening session Monday: 8h30 to 9h15 Norway's energy situation: Oil, Gas and Hydro Power - Norway as a pump storage power plant for Europe, by Odd H. Hoelsæter, President & CEO of Statnett Odd Håkon Hoelsæter is President and CEO of Statnett SF (The Norwegian Power Grid Company). Stanett SF is the Norwegian System Operator, the owner of, and operates the major part of the high voltage transmission grid in Norway and the interconnections with foreign countries. Statnett is also the owner of 50 % of Nord Pool ASA, the Nordic Power Exchange. Since Stanett SF was established in January 1992, Mr. Hoelsæter has possessed the post of President. Mr. Hoelsæter obtained his electrical engineering degree (Msc) at the Norwegian Technical University in 1969. He started his career with Samkjøringen av Kraftverkene i Norge (The Norwegian Power Pool). He left the Pool in 1980 to first take up the position of Technical Manager at Årdal og Sunndal Verk AS and then as Director for Hydro Aluminium Energy in Årdalstangen. He then rejoined the Norwegian Power Pool in 1989 as Executive Vice President. Currently, he is a Board Member of Employers' organisation of Norwegian State-Owned Enterprises; Vice President of NORDEL and the Norwegian representative to Eurelectric's section SEN. He is a former member of UNIPEDE's Large Systems and International Interconnection Study Committee. Keynote 1: Monday: 14:00 to 14:45 Integration of power components, state of the art and trends, by André A. Jaecklin, ABB, K. Rischmüller, SGS-Thomson Microelectronics and Leo Lorenz, Siemens Part 1 by A. Jaecklin The field of high power applications has recently experienced a strong push from advances in device development. On one hand, Insulated Gate Bipolar Transistors (IGBT) in the form of hybrid modules are continuously increasing their limits in current („ 1500 A) and voltage (up to 4500 V). In the highly demanding market of traction applications, reliability has become on of the crucial issues, however. On the other hand, based on the classical Gate-Turn-Off thyristor (GTO), a new element has been conceived, called the Integrated Gate Commutated Switch (IGCT). This device implies a rigourously reduced leakage inductance combined with a gate drive unit implemented into the structure. Applying a hard gate drive (hard driven GTO) opens the way to high voltages (> 10 kV) by means of multiple series connection as well as to reduced losses due to snubberless operation. Essentially, these two approaches are complementary. Part 2 by K. Rischmüller This part was not available by the time of printing Part 3 by L. Lorenz Power semiconductor components, including their further development as monolithic power ICs, and hybrid system integration are the driving forces behind advances in power electronics systems, particularly with regard to energy savings, improved control response, noise redustion, size and weight reduction and cost minimization. The first attempt at hybrid integration was the implementation of IPM's, ASIPM's and PIM's. The PIMs and ASIPMs currently known consists of a package containing all the power switches including brake chopper with drive/protection circuitry. However, today's IPMs, ASIPMs have several advantages concerning interface, cost and system requirements. As a result of all these disadvantages, these solutions have no future and will be superseded by system integration in the medium term. This paper highlights the new approaches to system integration based on chip level. The authors: André A. Jaecklin is Head of Basic Development with ABB Semiconductors. He is also Titular Professor at the Swiss Federal Institute of Technology K. Rischmüller was head of application systems with Sescosem, after Thomson Semiconductors and is currently with SGS-Thomson Microelectronics. He is author of numerous application notes on power semiconductor devices. Leo Lorenz is involved in the development of power semiconductors with Siemens in Munich. For 10 years he is in a management position in several areas of power semiconductors . Tuesday 14:00 to 14:30 Needs for solutions and new areas of applications for power electronics by Prof. Lars Gertmar, ABB Corporate Research and Lund Institute of Technology The keynote speech will partly serve as a visitor',s guide for the delegates. Based on available information on EPE'97 papers and some previous ones, some of the achievements will highlighted as specific examples and as an introduction to the two following sections of the speech. The second part will cover the trends in some societies and the potential applications of the power electronics in Transmission & Distribution, T&D and Adjustable-Speed Drives, ASDs. There are challenges to generate electrical power from various sources to transmit & distribute power as well as to save energy. The competition between electromechanics and power electronics will also be a subject as well as hybrid solutions, especially in T&D. Finally, the author hope to challenge the audience to focus their future work not only on incremental steps on existing and nearby technologies but also on paradigm shifts towards compact, light-weight, easy-to-install, low-emission, compatible and sustainable solutions based on power electronics. The author: Lars Gerttmar is Corporate Senior Scientist at ABB, in Electrical Machines and Drives Professor at LTH, in Power Electronic Drives D.Sc. at CTH, in Power Electronics, Ph.D. in Electrical Machines. He has 17 years industrial experience from R&D and product development partly also from practical troubleshooting on electric machines, power electronics, drives and electric measurements. 15 years experience from university R&D as well as under- & post-graduate education Experiences as manager, project leader, senior scientist coordinator (invited) lecturer, referee, etc. and from ABB's visionary & strategic works, R&D program boards and management, etc. Wednesday 14:00 to 14:30 The electric vehicle, by Prof. Hans Kahlen, University of Kaiserslautern, Germany and Prof. Gaston Maggetto, Vrije Universiteit Brussel, Belgium The interest and importance of electric and hybrid vehicles is nowadays in a very strong promising phase. The state of California has defined by law an introduction programme imposing 10 % sales of electric vehicles by 2003 and 25% of hybrid vehicles i.e. a market of respectfully 300.000 electric and 750.000 hybrid vehicles. Other states are following the same regulations. In Europe, countries such as France, Switzerland, Sweden, Belgium, ... are also demonstrating big interest through a number of programmes going from pure market penetration up to R&D activities. Japanese car manufacturers seems to engage a competitive action against the american 'big three" colleagues. In such a contest, it is clear that technology has reached a high grade of maturity but undergoes in the same time a rapid evolution. The scope of this keynote is to describe and discuss the state of the art in the field of motorisation, power electronics, converters, charging infrastructure and surely batteries and all types of energy sources for hybrid vehicles. The authors are well-known experts in the field. They will provide basic information, more specialised information and show the way for the necessary R&D activities such as for demonstration activities The authors: Prof. H. Kahlen is Professor at the University of Kaiserslautern. He is Past-President of AVERE, the European Association of Road Electric Vehicles. Formerly, he was responsible of the Brown Boveri (presently ABB) programme for drives for electric vehicles and the development fo the NaS battery. He is involved in a number of EU programmes concerning electric vehicles and batteries. He has more than 25 years experience in the field. Prof. G. Maggetto is Professor at the Vrije Universiteit Brussel, President of the Belgian Section of AVERE, Vice-president of AVERE, Secretary General of CITELEC, Association of cities interested in electric vehiles. He is also responsible for the world conference on electric and hybrid vehicles, EVS-15 in 1998 and is involved in a number of EU programmes concerning electric and hybrid vehicles. He has more than 20 years experience in the field. Back to main pageTop of page
