The 18th International Expert Meeting – Power Engineering was prepared in 2009 by members of our program group at the Faculty of Electrical Engineering and Computer Science. Statistics: approximately 150 participants from Slovenia and Europe, 31 papers and 7 invited lectures.

COBISS.SI-ID: 13347350The objective of the study has been to investigate trends in the use and installation of air and SF6 insulated switchgear and any other news (inert gas, etc) in the insulating media and propose optimal solutions. Further requirement has been to explore the consequences of the use of SF6 gas as insulating medium in middle voltage devices, and the issue of the decommissioning of facilities and potential environmental taxes.
F.17 Transfer of existing technologies, know-how, methods and procedures into practice
COBISS.SI-ID: 13363222The probability analysis of reliability offers a quantitative evaluation, for example: whether creating an additional line from the same or different transformer station is legitimate. It may be a criterion for covering the expenses – to the company for energy supply or the consumer who finds the extra supply unnecessary.

COBISS.SI-ID: 13725206This work deals with analysis of operation of cascaded power plants on the Drava River. It is found out that calculated water discharges might contain certain errors due to non accurate water head measurements, which is a problem for short-term scheduling of power generation. The identified defects have been immediately eliminated, which can have some positive effect on further operation of the system. The developed model of cascaded power plants on the Drava River will be used for further optimization of short-term power generation scheduling.

COBISS.SI-ID: 13678614This work deals with the calculation of copper losses in welding transformer with numerical, analytical and experimental methods. Numerical calculation is based on finite element method (FEM) and includes 2D and 3D finite element models. The proposed analytical method is modified so that it can be applied on the particular type of the tube-shaped secondary windings of the welding transformer. Measured copper losses are determined, with the available equipment, in the frequency range from 0.5 kHz to 1.7 kHz. The agreement among analytical, numerical and experimental results is good.
