Abstract

Developing wind farms located in cold climates is challenging as the environment is harsh. Icing conditions must be addressed carefully as the ice affects the shape of the blade, leading to low performance and higher production losses. In general, an estimated value of icing hours is used during pre-construction studies to represent the icing conditions on the investigated site. It is well understood that ice is dependent on height. However, during the development process of a wind farm, ice losses are calculated for the average height of the wind farm. It is expected that wind turbines at low elevation will face lower icing hours and will be compensated by the turbines at a higher elevation. The present work, performed by CGN Europe Energy, evaluates the sensitivity of instrumental icing with altitude, using operational data from several wind farms located in Sweden.
