Sten Tronæs Frandsen


Previous appointments :1976-1986: scientist at Physics Dept. Risø; 1985-1986 : Solar Energy Research Institute (now NREL), Colorado, USA ;1986-1993: Head of wind engineering group; 1995-1996: Head of wind systems group.


Key qualifications : Wake loads in wind farms; Array efficiency of wind farms; Wind turbine performance testing, in particular uncertainty analysis of power output (co-author of Danish standard, IEA and IEC standards on the issue); structural design of wind turbines; wind load on civil engineering structures; wind energy project formulation and feasibility studies, appraisal of projects etc.; 15 years experience in project management of projects in developing countries.


Current committee memberships : International ElectrotechnicalCommittee (Maintenance team IEC-MT01 on safety and design (IEC61400-1; working group IEC-WG03 on offshore wind turbines; Dansk Standard (Danish Standard) Committee S588.




Awarded the degree of Doctor Technices from the Technical University of Denmark, Since 1918, DTU has awarded the doctorate in technology (dr. techn.) to 200 people.


Contributor to the second assessment report on climate change under Inter-governmental Panel on Climate Change (IPCC). IPCC earned the 2007 Nobel Pease Price.


Selected experiences : Sten Frandsen (SF) has more than 30 years of experience within wind power research and development, of which the last 10 years increasingly has been focused on offshore applications. SF’s research has covered flow and structural mechanics as well as experimental techniques. Specifically the following can be mentioned.


·        Participation in development of the first generation frequency domain wind turbine structure model.


·        Development of methods for power curve measurements for wind turbines, including uncertainty analysis. This method is presently applied in national and international standards.


·        Analytical models for the interaction between very large wind farms and the atmosphere.


·        Model description of the turbulence within wind farms. The model is implemented in the Danish wind turbine standard and is being integrated into international standards as well.
