Modelling of Ice Storms and their Impact on a part of the Swedish Transmission Network
Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
In this master thesis a weather model to simulate an ice storm is developed. Precipitation, wind and movement are modelled by mathematical functions to create a realistic model.
The weather model is used to calculate wind and ice loads on power lines. Two dierent models for the ice accretion on the power lines are used and compared. Data from two storms in Sweden in 1995 and 1999 are studied. In the simulations, the precipitation is assumed to fall as freezing rain instead of snow. The ice and wind loads are calculated in detail for two power lines in southern Sweden. The calculated loads are compared to what is assumed to be the critical loads for the poles, and the risks of power outages in connection with these storms are discussed.
