Short summary:

This Ph.D. work concerns itself with the atmospheric ice accretion on wind turbine blades. Two main topics have been considered in this Ph.D. work: the atmospheric ice accretion on wind turbine blade and the performance losses associated with it; and the wind resource assessment in the ice prone region. Both topics are of major importance to wind energy in cold climate regions, due to the challenges present in the form of potential icing conditions and events, and the resultant energy production losses. The results obtained in this Ph.D. thesis shows that power losses due to icing on wind turbines occur not because of a single reason, but through a combination of effects that need to be taken into account carefully during the wind park design process. The results obtained in this work also provide the need and motivation for improving the understanding about icing effects on the wind turbine blades and the improvement of the existing (or creating new) anti-/de-icing technologies.
