Recommendations for load validation of an offshore wind turbine with the use of statistical data: experience from alpha ventus

摘要

The present paper provides insight into the validation of computer models used for simulations of offshore wind turbines. The offshore turbines are affected environmental conditions that must be logged during the measurement campaign of the prototype and used for the simulations during the validation. A simple generic methodology is presented to be used for the comparison of statistical data from the measurement campaign and the simulations. This allows a better analysis of the simulations and helps limit the apparition of outliers in the measurements. An example of the use of the methodology is provided with the use of the data recorded for the AD5-116 5MW turbine at alpha ventus. For it the turbine power, operational parameters and blade and tower loads are compared.
