Influence of the type and size of wind turbines on anti-icing thermal power requirements for blades

Ice accretion on wind turbine components affects system safe operation and performance, with an annual power loss up to 20–50% at harsh sites. Therefore, special design requirements, as ice prevention systems, are necessary for wind turbines to operate in cold climates. The paper presents results for evaluating the anti-icing energy requirement for wind turbine blades as a function of wind turbine size and type. The analysis was carried out by means of the TREWICE code tool
