Summer 2005 PELINCEC Newsletter http://pelincec.isep.pw.edu.pl No. 8

In this event on Wednesday 30.03.2005 Professor Henryk J.

Tunia, commonly known as founder of Power Electronics in

Poland, in a very systematical way has presented four hours

Seminar devoted to multi-phase transformers and autotrans-

formers in power converter systems. This topic is currently

very important because of developments in renewable energy

sources (wind and solar energy) as well as power quality

problems. After an Introduction Professor Tunia discussed

following topics: Multiphase Transformers - Multipulse Tech-

nique for High Harmonic Reduction, Autotransformer - Cir-

cuits and Analysis, Three-Phase Coupled Reactors for Paral-

lel Operation of Rectifiers, Low Frequency Technique of THD

Reduction in Rectifier Systems.

The Seminar was connected with Prof. Tunia’s Jubilee of

80 Birthday Anniversary. Therefore, beside of over 30 PhD-

Students and all professors of the Institute of Control & Indus-

trial Electronics also several professors from other Polish

Technical Universities participated in this Seminar (Prof.

Please allow me to remember some key facts from Prof. Tu-

University in Gliwice, in 1954 he joined Faculty of Electrical

Engineering at the Warsaw University of Technology as

Ph.D.-Student (Aspirant) and parallel cooperated with the

industrial Institute of Electrotechnics (IEl) in Warsaw-

Miedzylesie as a research adjunct. His PhD-thesis entitled

“Analysis and Synthesis of Thyratron Controlled DC Motor

Drive” defended in 1960 was the first scientific work in the

area of Power Electronics in Poland. It should be noted that

at that time Power Electronics was not popular in Poland and

was lack of basic textbooks. Therefore, Prof. Tunia with His

Tutorial on Matrix Converters

Domenico Casadei

Introduction Three-phase matrix converters have received considerable attention in recent years because they may become a good alternative to voltage-source inverter pulsewidth-modulation topology. This because the matrix converter provides bi-directional power flow, nearly sinusoidal input/output wave-forms, and a controllable input power factor. Furthermore, the matrix converter allows a compact design due to the lack of dc-link capacitors for energy storage. The aim of the tutorial is to present the basic features of three-phase matrix converters in order to emphasize ad-vantages and disadvantages with respect to more tradi-tional topologies of three-phase AC/AC converters. In particular the tutorial will cover the following topics: Part I: Basic features of matrix converters

- bidirectional ac switches, - four-step and three-step commutation strategies, - SVM control of matrix converters, - input/output characteristics of matrix converters.

Part II: Control methods - comparison among different input current modulation strategies for matrix converters with unbalanced sup-ply voltages,

- compensation of the low order input current harmon-ics,

- stability analysis of electric drives fed by matrix con-verter,

- methods to improve the stability of matrix converters, - comparison between the performance of a matrix con-verter and a back-to-back converter.

Expected duration of the talk: 4 hours (45 min. each).

Expected duration of the talk: 4 hours (45 min. each).

Tutorial on Wind Energy

Frede Blaabjerg

Wind energy is the fastest growing renewable energy tech-nology. More than 40 GW is installed globally and in the future much more will come. The wind turbine grow in size. Today the largest are 5-6 MW and such units have a major impact on the grid system. One of the methods to improve the interconnection is to use power electronics which en-able the wind turbine to be a real power source for the power system. This tutorial will discuss the wind turbine technology, power electronic converters, interconnections issues and standards, control of wind turbines and wind power station configurations placed either on-shore or off-shore. At last some trends will be discussed.

This year the WATAB Seminar will be organized in conjunction with PELINCEC2005 Conference and will be located in a sepa-

rated WATAB-Sessions. We do hope that WATAB will contribute to Conference attractiveness. Our PhD-Students will present

their projects in Laboratory Tours offered for the PELINCEC2005 participants.

The social Program of the PELINCEC2005 will include Welcome Chopin Concert on Monday, 17 October, 2005 in the

Ostrogski’s Palace and Gala Dinner in the Main Aula of Physic Department, Warsaw University of Technology on 18 October,

2005. Also, several excursions will be offered for accompanied persons (Warsaw and Krakow sightseeing tours, Żelazowa
