About the position

The Faculty of Information Technology and Electrical Engineering at the Norwegian University of Science and Technology (NTNU) has a vacancy for a three-years position as a PhD Research fellow at the Department of Electric Power Engineering. The described PhD is part of the research within the Norwegian Centre for Hydropower Technology. The work will be part of work package 2 in HydroCen in a team with a PhD research Fellow working on digital monitoring of Pelton turbines. (https://www.ntnu.edu/hydrocen).

About the Norwegian Centre for Hydropower Technology (HydroCen)
HydroCen is a Centre for Environment-friendly Energy Research (FME). The FME scheme is established by the Norwegian Research Council. The objective of the Research Council of Norway FME-scheme is to establish time-limited research centers conducting concentrated, focused and long-term research of high international caliber to solve specific challenges in the field. The FME-centers can be established for a maximum period of eight years.

The main objective of HydroCen is to enable the Norwegian hydropower sector to meet complex challenges and exploit new opportunities through innovative technological solutions. The research areas include; hydropower structures, turbine and generators, market and services, and environmental design. NTNU is the host institution and main research partner together with SINTEF Energy Research and the Norwegian Institute for Nature Research (NINA).

You will report to the Head of Department.

Duties of the position

Job description

The objective of the PhD education is to qualify for scientific research of high international standard. The PhD education has a nominal duration of three years of full-time study and includes required coursework or similar academic training comprising a minimum of 30 credits. The most important component of the PhD education is an independent scientific research project carried out under academic supervision, which results in the PhD thesis. The PhD degree is conferred based on these two elements and the doctoral examination, which consists of a trial lecture and a public defence of the scientific thesis.

The candidate is expected to fully complete the course work and the PhD thesis within the period of employment, which could be 3 or 4 years. The doctoral examination may take place after the period of employment. The option of 4-year employment would imply 1 year of duties as Teaching Assistant for the Department and may be offered to a candidate with clear motivation and ability for such work, if the Department sees the need. This will be clarified during and after any interview.

Project description

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. Considerable wind power generation capacity has been installed the last years and more both on- and offshore installations are expected. This increases the need for balancing hydro power and the burden on the hydroelectric aggregates. At the same time, it is a continuous pressure to reduce operating costs of the units. Thus cheap, accurate and sensitive detection of faults becomes more important. 

The research is a continuation of on-going research on fault detection and identification using electromagnetic signatures. Through previous research efforts, methods using electromagnetic signatures and advanced signal processing have been used to detect a variety of faults. This comprises several mechanical and electrical failures in the rotor. A sensor system with signal processing software has been developed and tested successfully. The research is on the international fore-front and patent protected.

In the continued research effort, stator mechanical and electrical faults are targeted. This induces stator core field joints, mechanical ovality and stator winding short. The PhD student is expected to be able to utilize advanced FEM numerical models combined with advanced signal processing and pattern recognition to identify targeted faults. 

Further, the possibility to recognize the faults signature using simplified methods making the method more applicable is a new objective in the development of the methodology. 

The results are expected to be confirmed by laboratory and field (power station) testing.

Required selection criteria

The applicant must hold a M.Sc. degree in Electrical Power Engineering. Knowledge and experience in electrical machinery, FEM-analysis and laboratory experience is beneficial. High motivation and good analytical and communication skills will be emphasized in the employment process.

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and Regulations concerning the degrees of Philosophiae Doctor (PhD) and Philosodophiae Doctor (PhD) in artistic research national guidelines for appointment as PhD, post doctor and research assistant  

Applicants must have very good English language skills, written and spoken. Applicants from non-English speaking countries outside EU/EEA/Switzerland must provide preliminary documentation of English language proficiency, in terms of an approved test. The following tests can be used: TOEFL, IELTS and Cambridge Certificate in Advanced English (CAE) or Cambridge Certificate of Proficiency in English (CPE). Minimum scores are:

  • TOEFL: 600 (paper-based test), 92 (Internet-based test) 
  • IELTS: 6.5, with no section lower than 5.5 (only Academic IELTS test accepted)
  • CAE/CPE: grade B or A.

Further assessment of both written and oral English language skills and the ability to communicate fluently will be conducted in the continued selection process and during any interviews for all applicants.

Preferred selection criteria

The ability to work in a team and good communication skills will be emphasized in the employment process. 

Personal characteristics

In the evaluation of the candidates, emphasis will be placed on education, experience and personal suitability, as well as personal motivation for the position, in terms of the qualification requirements specified above. We look for candidates who show clear signs of independence, original thinking and scientific mindset.

Salary and conditions

PhD candidates are remunerated in code 1017, and the salary is NOK 491 200 before tax per year. From the salary, 2% is deducted as a contribution to the Norwegian Public Service Pension Fund.

The employment contract is for three years; however, there is a possibility for extension up to four years if selected for assistantship.

Appointment to a PhD position requires that you are admitted to the PhD programme in Electrical Power Engineering within three months of employment, and that you participate in an organized PhD programme during the employment period.

As a PhD candidate, you will have to successfully complete the PhD academic training programme; the training includes mandatory course work and other obligatory activities. Within the first three months of your employment, you must formally qualify for admission to the PhD programme at the Faculty of Information Technology and Electrical Engineering. 

The Department of Electric Power Engineering works closely with key players in the Norwegian electricity supply sector, who manage critical infrastructure. A comprehensive risk assessment of the candidates' research interests and potential activities related to national threat assessments will therefore also form basis for the final selection of candidates.

The engagement is to be made in accordance with the regulations in force concerning State Employees and Civil Servants, and the acts relating to Control of the Export of Strategic Goods, Services and Technology. Candidates who by assessment of the application and attachment are seen to conflict with the criteria in the latter law will be prohibited from recruitment to NTNU.
