Quality of synthetic winds by testing of similarity to measured data by spectral modelling and statistics of increments

摘要

For analyses of fatigue loading of wind turbines and their control schemes via numerical simulations detailed information on the 3D wind field are necessary. Schemes for the generation of respective synthetic sets had been developed and are in use. There is a need for the validation of these schemes in view of the realistic representation of statistical characteristics of the real wind field. This comprises - besides the correct reflection of the spectral properties of the field - the reflection of non-Gaussian properties of the series. In this paper we report on the analysis of synthetic data from a full-field, turbulent wind simulator by comparison with highly time resolved measured wind data sets.
