Blade icing is a major issue for wind farms in cold climate areas, decreasing energy production (up to 15% and more, depending on the site) and potentially reducing wind turbine generators (wtg) lifetime (vibration phenomena). Around 100 gw (about 25 % of worldwide installed capacity) are estimated to be installed in so called â€œcold climateâ€¿ areas (mainly scandinavia, elevated areas of central europe, canada, china and northern parts of the us), and further installations are foreseen in the next years at a rate of 10gw/year.
current technologies to reduce machine shutdown time are lacking maturity: opportunities exist therefore for companies developing innovative solutions for harsh climates. Both effective means to detect when the machine is frozen and protective solutions avoiding frost accretion are needed; such solutions shall adapt to the current wtg structure, â€œretrofitâ€¿ being a key issue.
the goal of the project is both to test existing solutions in retrofit mode and to participate in the development of new innovative ones, covering all the aspects of the problem: ice detection, de-icing solutions, anti-icing coatings, icing modelling/simulation and forecast of ice formation conditions. Tests will be hosted both in controlled environment (lab facilities) and on the field, on real wtg
