Lataire, A. Børnes, K. Ryen and T. Chr. Stensholt. EPE offers the EPE'97 conference participants a package including: - the technical visit to the Statoil Kollsnes gas terminal plant at the outmost western island of Norway on 6 September 1997; - transportation by bus along the Bergen archipelago to Kollsnes from Bergen City Center or Airport and back to the costal express M/S Polarlys (departure on 6 September at 22.30, arrival on 8 September at 06.00); - tutorials at Kollsnes and on board of the Polarlys and technical visit of the ship. The Statoil gas terminal plant in Kollsnes processes the natural gas coming through an undersea pipeline from the 472 m high off-shore Troll platform (measured from the sea-bed) operating the centre of the world largest offshore gas field.. The core of the plant are 5 gas compressors individually driven by adjustable speed 41.2 MW synchronous motors. Particularly interesting are the harmonics filers which are designed to meet the specified harmonics content. The filter design was a challenge due to the cable and overhead line mixture in the power supply to the plant. The gas transferred to Germany represents 400 TWh per year energy equivalent, corresponding with a constant power of 45 GW.

Adjustable speed a.c. motor drives, applications by P. Enjeti, F. Blaabjerg and J. K. Pedersen. Summary Adjustable speed a.c. drives have become the preferred choice in many industrial applications where controlled speed is required. At the availability of fast solid state power semiconductor switches (IGBTs) has resulted in voltage source, PWM controlled inverters becoming a standard configuration in the power range to 500 kW. While high frequency PWM control represents the most advanced drive concept, when inappropriately applied, it also generates side effects, some of which have been recognized only recently. This course present a comprehensive coverage of application issues of PWM inverter controlled a.c. motor drives which include: selection criteria for energy savings, increased motor losses: damage to motor insulation due to reflected voltages caused by long motor leads, acoustic noise problems and solutions for sensor-reduction. Following a description of the problems, several practical solutions are also presented and nanlysed. Finally, line harmonic problems caused by the input diode rectifier are also described and several low cost solutions selected to meet IEEE 519-1992 are presented. Basic content Introduction to ASDs, application problems and energy savings; Introduction of application problems to high dv/dt and long motor leads; Filter configurations to minimize the motor winding stresses due to high dv/dt; Application problems due to high dv/dt - continued; Acoustic noise problems and their reduction; Reduced sensing technique in ASD and their problems; Power quality compliance of ASD equipment. The audience PWM inverter/motor manufacturers, system designers as well as adjustable speed drive application engineers and users will find this course informative and beneficial.

Design and simulation of mechatronics applications and power electronic systems with Matlab/Simulink by S. Colombi The presentation starts with some general considerations about the numerical simulation of a system (modeling, integration algorithms, quantization and numerical problems). Then, after a short overview of Matlab/Simulink, various industrial application examples in the fields of power electronics and mechatronics are described. The first example is a step up-down converter. The mechatronics applications are: simulation of a pseudo-linear system (friction and stiction), frequency-voltage control of an induction motor, vector control of an induction motor, wrist stiffening of a bilateral Master-Slave force reflecting servomanipulator, control of articulated boom of JET (Joint European Torus) and finally, active control of an electromagnetic suspension system. For each application example, the teaching includes a theoretical part (modeling, control design) followed by the validation on a PC. As a conclusion, general design methodologies are outlined and advantages and drawbacks of Matlab/Simulink are summarised.

Understanding and complying with CISPR and IEC 1000 Standards on EMC, by A. Zuccato, L. Rossetto. Since January 1996, electrical and electronic equipment sold in the European market must bear the CE mark which attests compliance to EMC standards, which take into account both radiated and conducted noises in a very wide frequency range (up to 1 GHz) and require several emission and immunity tests (including electrostatic discharge, fast transients, surge voltages etc.). The first part of the tutorial reviews the standards regarding low-frequency emission and immunity to line disturbances, and in particular IEC 1000-3-2 which limits the low-frequency harmonic distortion (from 50 to 2000 Hz) of equipment with rated current less than 16 A per phase. Common problems and misunderstandings in applying the norms are addressed and operational experience is reported for various families of industrial and domestic loads. Then, basic passive and active power factor correction techniques are illustrated and compared. The second part of the tutorial reviews CISPR and IEC standards regarding conducted and radiated noise emission and immunity. Typical problems arising from their application are discussed from a practical point of view and mitigation guidelines are given. Lastly, the design of a power factor corrector circuit complying with all the above standards is illustrated.
