Production data - May Production data - November
Ice formation on rotor blades influences the aerodynamic properties of the blades leading to large power losses in the wind farm. Production losses of 50 % or more have been observed during winter months characterized by icing with heavy intensity. Icing can thus result in large annual production losses.
IceLoss is a state-of-the-art method developed by Kjeller Vindteknikk which gives an estimate of the expected icing losses of a wind farm based on simulations with the mesoscale model WRF, combined with post-processing algorithms developed by Kjeller Vindteknikk. IceLoss is calibrated with operational wind power plants.
An IceLoss analysis gives the following:
- Hourly time series of ice load and icing intensity taking into account ice accumulation, melting and sublimation.
- Long-term estimate of the icing losses.
- Calculation of the icing losses assuming that the turbines can operate during icing conditions, and assuming that the turbines must be stopped during icing conditions.
- Hourly time series of the icing losses for turbines with and without heated blades.
- Local icing climatology including the wind directions that contribute the most to icing.
