About the position

Are you motivated to take a step towards a doctorate and open up exciting career opportunities? Are you interested in advancing environmentally friendly hydropower technology, and do you have a strong competence in electric machinery and electromagnetics? As a PhD Candidate with us, you will work to achieve your doctorate, and at the same time gain valuable experience that qualifies you for a further career in higher education and research, in and outside academia. 

The Department of Electric Energy (IEL) at NTNU is seeking a highly motivated candidate for a full-time (100%) PhD position for 3 years as part of the project “Modelling and analysis of pumped storage hydrogenerators”. The project is linked to the new research center FME RenewHydro. You will join the research group Electrical Machines and Electromagnetics (EME) at IEL, where we foster an open, inclusive, and collaborative working environment.

Our working environment is characterized by its friendly and supportive atmosphere, with regular gatherings such as professional meetings within the research group, monthly colloquia, shared lunches, and “Friday coffee” sessions to wrap up the week. These formal and informal occasions provide opportunities to exchange ideas, celebrate milestones, and strengthen connections. PhD candidates also arrange social activities, open to everyone who wishes to join, creating a welcoming and inclusive community.

Your immediate Line Manager will be the Head of Department.

About the project

FME RenewHydro

FME stands for Centre for Environment-friendly Energy Research and FME RenewHydro is a new research center for environmentally friendly energy developing hydropower to be more flexible and contributing to more sustainable renewable energy. With increased cooperation and new knowledge in technology, markets, environment and society, the research center RenewHydro will work to reach national energy, climate and nature targets.

In RenewHydro, researchers in the fields of technology, biology, economics, society and climate will collaborate with experts from the hydropower industry and public administration to solve key challenges in the energy field, develop solutions for a low-emission society and strengthen the business community's ability to innovate. 

In addition to technology for the hydropower plants themselves, the researchers will look at, among other things, security of supply, how climate effects change hydropower, how the power can and will develop, and how hydropower can take into account the environment in rivers and reservoirs in the form of nature-based solutions. 

We face major challenges in the future. Climate change will affect the whole society, including hydropower and nature. In RenewHydro, we will therefore focus much more on the major connections with biological diversity, sustainability and land use. 

NTNU leads the center and the main research partners are the Norwegian School of Business NHH, the Norwegian Institute for Natural Research - NINA and SINTEF Energi. The centre duration is from 2025 till the end of 2032. 

About the PhD project

The research topic is on modelling and analyzing losses and vibration in hydropower generators fed from frequency converters for variable speed operation in pumped storage hydro plants. This applies for both converter-fed synchronous machines and doubly fed induction machines.

Norway is in the unique position that all domestic power consumption is covered by hydropower. In addition, Norway has 50% of Europe’s hydropower reservoir capacity (about 80 TWh). Considerable wind power generation capacity has been installed the last years and more both on- and offshore installations are expected. We foresee a partly conversion of hydropower plants with reservoirs into pumped storage to facilitate inclusion of more unregulated wind power generation. 

Variable speed operation offers several advantages over traditional constant speed operation and is now under consideration for new pumped storage plants. The use of converters may initiate more complex force and vibration patters in the machine and causing higher losses due to harmonics in voltages and currents. 

The main supervisor of the PhD candidate will be Professor Arne Nysveen (IEL). Co-supervisor(s) will be appointed. 

Duties of the position

• Familiarize with hydropower station design and operation
• Development and application of loss models for additional loss calculation of electrical machines fed from frequency converters
• Modelling and analysis of vibration issues on converter fed machines
• Experimental verification in laboratory and field tests in power stations if possible
• Academic publications and dissemination. Researchers in RenewHydro are expected to contribute regularly to internal and external seminars with research partners and sponsors.
• Participate in international activities such as conferences and/or research stays at foreign educational institutions
• Participate in activities of the research group Electrical Machines and Electromagnetics (EME)
• Complete academic training consisting of coursework corresponding to a minimum 30 ECTS.

6 months of duty work may be offered to the PhD candidate with clear motivation and ability for such work. This type of work comes in addition to the research project and doctoral education and provides valuable experience for future careers in academia or other sectors. Examples of duty work can be, but are not limited to, teaching, supervision, and examination work within the candidate's area of competence. 

Changes to your work duties after employment may apply.

Required selection criteria

• You must have a Master's degree in electric power engineering.
