Vacant job

Luleå University of Technology is experiencing rapid growth with world-leading expertise within several research areas. Our scientific and artistic research and education are conducted in close collaboration with international, national and regional companies, the public sector and leading universities. Luleå University of Technology has an annual turnover of just over SEK 2.3 billion. We have more than 1,800 employees and nearly 21,600 students.

Electric Power Engineering is part of the Division of Energy Science within the Department of Engineering Sciences and Mathematics. Within Electric Power Engineering, we maintain close collaboration with industry and public authorities through both research projects and student projects. Our research is conducted at a high international standard and is carried out in cooperation with researchers from around the world. In the field of power quality, the subject enjoys a strong international reputation thanks to its world-leading research.

Subject description

Electric Power Engineering covers studies of sustainable systems for the production and transportation of electrical energy, and the interaction between the power grid, electricity production, and electricity consumption.

Project description

The project aims to develop models that describe how HVDC installations affect, and are affected by, power quality in electrical networks up to 150 kHz. Measurements will be used to further develop existing models and to distinguish between primary and secondary emissions as well as nonlinear interactions. The results will provide the basis for a generalized model of emission and immunity related to HVDC installations. The study will also investigate network resonances, interactions between multiple HVDC installations, and the effects on transformers and other grid-connected equipment. The project is carried out in collaboration between Luleå University of Technology (LTU) and Hitachi Energy.

Duties

A PhD position involves both theoretical and practical work. As a doctoral student, you will be trained in scientific research through the publication of journal articles and presentations at national and international conferences. You will also complete both mandatory and elective doctoral courses. In addition, you may have the opportunity to gain teaching experience.

As a researcher, you often work as a neutral party in various contexts, providing an excellent opportunity to learn how to manage and contribute to challenging development and research projects. Your work will primarily focus on theoretical modeling and simulations, although laboratory and field measurements may also form part of the research activities.

Qualifications

You are qualified to apply for this position if you have an MSc or equivalent technical degree with specialization appropriate for research in electrical power engineering such as electrical engineering, electronics, energy, engineering physics or similar areas. Alternatively, an individual fulfills the general eligibility requirements for the third-cycle educational program when he or she 1) has completed a second-cycle degree, 2) has completed higher education courses worth at least 240 credits, of which at least 60 are for second-cycle courses, or 3) in some other manner, in this country or abroad, has acquired the equivalent qualifications courses in electrical engineering. Advanced knowledge of written and spoken English is required. Previous experience in research, development or research-oriented education in a subject relevant to the tasks is considered a merit. In addition, ability to contribute to the education done by the group (in Swedish) is regarded as meriting.
