Abstract
The existing widely used models of power line icing in
freezing precipitation are conceptully evaluated. The
reasons for the different predictions by die models are
pointed out, and it is shown that none of the models is
both correct and complete in predicting design glaze ice
loads.
Improvements to the modelling are proposed and a new
comprehensive numerical model is presented. This model
includes detailed simulation of icicle growth.
The results of the new model show that earlier models
underestimate ice loads under certain conditions.
Furtherniore, the new model shows, that ice loads formed
close to 0 °C may be much higher than those formed at
lower temperatures, other conditions being the same.
