Department of Electric Energy

At the NTNU Fakultet for informasjonsteknologi og elektroteknikk (Faculty of Information Technology and Electrical Engineering) we appreciate each and every of our employees. To give spesial attention to employees that give extraordinary contributions , the Faculty has established three awards. Our own professor Dimosthenis Peftitsis won this year’s award for internalization, a well deserved award. The award for contributions to the work environment went to Tove Kristin Blomseth from Department of Engineering Cybernetics, and the award for reached/education went to Erik Folven from Department of Electronic Systems. Congratulations to all three winners.

Today our Head of Department, Anngjerd Pleym, and Head of Department Thomas Tybell from Department of Electronic Systems met some of the first year students in our BSc program in Electrical Engineering for a dialogue session. We talked about what our aims for the program is an what students can do to enhance both their technical competence and their skills related to teamwork. We also got some Good feedback that we will use to improve our teaching. Photo: Irina Oleinikova.

As part of the research project, SwoP (Impact of switched voltage waveforms on power components and grids), University of Bologna, NTNU, and SINTEF have an open position for a Researcher position. You can find the job listing here: https://lnkd.in/dYYRnidW Deployment of power electronic converters (PEC) are central for reduction of CO2-emissions through electrification of society. PECs function as on/off switches and allows for precise control of power flow in electric components, such as in variable speed drives (motors) used in electrical vehicles. The on/off switching results in sharp-edged square wave voltages with high repetition rate. These sharp voltage flanks introduce different stress distributions internally in components and can induce or accelerate degradation and lead to premature breakdown. Failure modes in electrical insulation will typically be partial discharges (PD), i.e., small local sparks that degrade insulation, and dielectric heating, but documentation of correlation between PD level and life expectancy is scarce. To manufacture novel and lightweight insulation systems for electric propulsion and renewable energy generation, knowledge is thus needed on degradation mechanisms and suitable insulation materials under PEC stresses. With increased understanding of degradation mechanisms and the underlying phenomena, we believe that even more efficient and reliable motors and power components for electrification can emerge.   The researcher will share the time between NTNU and University of Bologna and be part of a group of scientists at the universities and SINTEF. SwoP is a competence building project for industry, with several international industry partners and universities. Read more about the project here: https://lnkd.in/dsRHhhQ2

Statnett SF is an important company for the Norwegian power system, being responsible for operating the Norwegian transmission system. Many of our clever students move on to work for Statnett, and we do research together. Today the Department has had a delegation present at Statnetts RD&I conference in Oslo. Professor Kjetil O. Uhlen gave a presentation on Wide area monitoring an control in the future Nordic power system. Irina Oleinikova Sjur Føyen Kjetil Uhlen Anngjerd Pleym

I dag var det vår tur til å være en del av Energidagen. Mine gode stipendiatkolleger har fortalt studentene om hvordan det er å være PhD-kandidat og om alt det spennende en kan gjøre i en PhD-jobb. Standen har vi delt med Institutt for energi og prosessteknikk som vi også deler studieprogrammet Energi og miljø med. (Foto: Frank Mauseth) #stoltinstituttleder #elektriskenergi #NTNU

I dag og i morgen foregår Energidagene her ved NTNU. En flott møteplass der studenter møter et mangfoldig næringsliv i energisektoren.

Yesterday was yet another festive day at the department. Our PhD candidate Paul Monceyron Røren defended his thesis entitled "Ablation-assisted load switching at medium voltage in an alternative gas to sulphur hexafluoride". His work has been done under the supervision of main supervisor professor Kaveh Niayesh with co-supervision from Magne Runde and Erik Jonsson Seither. The committee who evaluated the thesis and contributed to good discussions throughout the day has consisted of Professor Dirk Uhrlandt and  Dr. Monica Magureanu with professor Frank Mauseth as the the third member and administrator. Congratulations to Paul!

The Department of Electric Energy covers a lot of topics within the field of electric energy, all they way from power production, transmission and distribution to the use of electric power. We also study how the electric energy system plays a role in our total energy system and how electricity markets are or should be working. In order to inspire each other and see possible cross discipline collaborations we have started a seminar series for the whole department. Today our PhD candidate Michiel Desmedt gave us insight into his work on counter-rotating twin-harmonic machine topology.

Last Thursday, 12.09, we enjoyed following the PhD defense of our PhD candidate Uğur HALDEN. Ugur's thesis is entitled "Advancing Power Systems: Harnessing the Potential of Artificial Intelligence and Disturbed Ledger Technology" and the work is done under supervision from main supervisor Ümit Cali and co-supervisor Vijay Venu Vadlamudi. The evaluation committee who contributed in a very nice way to making the day memorable through good and deep discussions with the candidate consisted of professor Chunming Rong from the University of Stavanger and associate professor Valentina Cecchi, Ph.D. and not the least professor Kaveh Niayesh who lead us all safely through the day. Congratulations to Ugur and his supervisors.
