About
Icing on power lines can cause major disruptions in electricity supply networks. These disruptions lead to excessive costs for repair as well as consequential losses. There is also a risk to human safety for employees tasked with the repair of power lines in harsh environmental conditions.
Icing on power lines is a problem experienced in most high-latitude countries of which Norway has some of the highest recorded ice loads. The main objectives of this project are:
- Develop and test cost effective sensors for real-time monitoring of ice loads in the grid.
- Develop an improved analytical icing model for icing of large objects.
- Develop probabilistic forecasting methods for short-term prediction of icing events.
- Improve the parameterization of wet snow in the WRF microphysics code.
- Develop a nationwide map of design ice loads including effects of climate change.
- Investigation and numerical modelling of technologies for ice reduction and removal.
