Overview of cold climate wind energy: Challenges, solutions, and future needs

Autor: Wallenius, Tomas, Lehtomäki, Ville

Publikováno v: Wallenius, T & Lehtomäki, V 2016, ' Overview of cold climate wind energy: Challenges, solutions, and future needs ', Wiley Interdisciplinary Reviews: Energy and Environment, vol. 5, no. 2, pp. 128-135 . https://doi.org/10.1002/wene.170

Wind energy in cold climates offers vast wind energy potential. Cold climate, in this context, means icing conditions and/or low temperatures outside the normal operational limits of the wind turbines. Cold climate areas are often located in low popu

Icing production loss module for wind power forecasting system

Autor: Karlsson, Timo, Turkia, Ville, Wallenius, Tomas

Publikováno v: Karlsson, T, Turkia, V & Wallenius, T 2013, Icing production loss module for wind power forecasting system . VTT Technology, no. 139, VTT Technical Research Centre of Finland, Espoo . < https://publications.vtt.fi/pdf/technology/2013/T139.pdf >

Icing conditions may cause significant wind power production losses, which increase short-term wind power forecasting errors if not taken into account. In this study real measurements and production data were used to evaluate a method to estimate pro

Autor: Laakso, Timo, Baring-Gould, Ian, Durstewitz, Michael, Horbaty, Robert, Lacroix, Antoine, Peltola, Esa, Ronsten, Göran, Tallhaug, Lars, Wallenius, Tomas

Publikováno v: Laakso, T, Baring-Gould, I, Durstewitz, M, Horbaty, R, Lacroix, A, Peltola, E, Ronsten, G, Tallhaug, L & Wallenius, T 2010, State-of-the-art of wind energy in cold climates . VTT Working Papers, no. 152, VTT Technical Research Centre of Finland, Espoo . < https://publications.vtt.fi/pdf/workingpapers/2010/W152.pdf >

Wind turbines in cold climates refer to sites that may experience significant time or frequency of either icing events or low temperatures outside the operational limits of standard wind turbines. The potential for producing electricity at such, ofte

The dependence of icing severity on chord length

Autor: Homola, Matthew C., Wallenius, Tomas, Makkonen, Lasse, Nicklasson, Per J., Sundsbø, Per A.

Publikováno v: Homola, M C, Wallenius, T, Makkonen, L, Nicklasson, P J & Sundsbø, P A 2009, The dependence of icing severity on chord length . in European Wind Energy Conference and Exhibition 2009, EWEC 2009 . vol. 6, pp. 4315-4319, European Wind Energy Conference and Exhibition 2009, EWEC 2009, Marseille, France, 16/03/09 .

The dependence of atmospheric icing on wind turbine size was revealed by performing numerical simulations of ice accumulation on four different wind turbine blade profiles. The profiles were for 450 kW, 600 kW, 1 MW and 2 MW wind turbines, and the si
