Agents icing and challenges on wind turbines

In this paper, after introducing the characteristics of cold climates, reviews the special equipment needed to safely exploit wind energy power systems in these locations and gives an updated picture of the current installations in the world. Then the analysis points at the effects of site elevation on inland plants. For these installations some aspects are often neglected or even ignored either in turbine design or in wind park development. Deviation from the standard density has a series of consequences both on power curve and loads, and if counteracting means are not adopted, the turbines suffer from poor performance and ruptures. Overview of offshore icing is also given. A brief introduction to issues concerning operations in icing conditions is given, in particular, the strategies and the special equipment are indicated, together with real indications of the penalties in annual energy harvest of existing wind parks.
