VALIDATION OF ICING MEASUREMENTS
Icing has become an area of increased interest for wind power since the development of new turbine parks sometimes are located where there is a risk of icing. There is a need for reliable measurements before establishing a park to assess the icing risk. An important part of understanding icing is to have access to good and accurate data. It is important to stress the need for accurate data since it will provide a basis for future research and also can be a basis for prospecting for a new wind turbine park, an inaccuracy in the data could have severe consequences. There are many instruments for measuring ice loads today on the market and it is vital that these instruments are accurate. To investigate the accuracy of the data available in the Vindforsk project in situ measurements have been compared to modeled data for icing events in Sweden during the winter season 2009-2010. The in situ measurements have been compared with ice load both modeled with COAMPS (Coupled Ocean/Atmosphere Mesoscale Prediction System) and in situ meteorological parameters. Using in situ meteorological parameters for modeling ice load show promise, as does using a mesoscale model. Though further investigation is needed since the modeled ice load is underestimated. The work presented is an ongoing project in which ice load data are being validated -calling the attention to the need for more measurement sites and validation. This need cannot be stressed enough, without trustworthy data many issues with icing will be left unaddressed.
