Research Projects Wind Engineering

Some of the research projects that Kjeller has been involved in so far.

Development of measurement and analysis systems based on synchronized scanning lidars

In this Skattefunn project, Kjeller Vindteknikk develops measurement and analysis systems based on synchornized scanning lidars to measure wind and turbulence conditions in wide fjords. The project links onto Kjeller Vindteknikk’s measurements work for Statens Vegvesen on several planned fjord crossings on the new E39 road. Wind and turbulence measurements are important input parameters during the design of bridges on these crossings, however, accurate measurements in the middle of the fjords can be challenging. Both acquisition setups and analysis tools are developed in the projects where 4 synchronized scanning lidars are set up in each fjord location. 


Kjeller Vindteknikk received funding from the Norwegian Research Council to develop a tool which estimates icing on transmission lines. The project Frontlines ran from 2015 to 2018 and engaged several renowned international research institutes and the main grid operator in Norway, Statnett.

Icing on transmission lines can in extreme cases cause line rupture if the transmission line is not dimensioned for sufficient ice loads. An improved understanding of the scale and location of icing can prevent future line failures and reduce transmission losses in the form of corona discharge. 



In corporation with the Norwegian Metrological Institute, Kjeller Vindteknikk participated in the WISLINE-project with the aim to study wind, ice and snow loads on infrastructure and the environment. The purpose was to quantify the impact from climate change on technical infrastructure and environment caused by severe wind, icing and wet snow.

The project is financed by the Norwegian Research Council and ran from 2015 to 2018. 


Wet snow on transmission lines

In cooperation with CEATI in Canada, Kjeller Vindteknikk is developing a worldwide overview over how ice load from wet snow is acknowledged in dimensioning of transmission lines.

On the background of this overview recommended design criteria on wet snow icing on transmission  lines will be developed and highlight potential deficiencies in national regulations.

The project was financed by CEATI and the final report was published in 2016.
