The new identification tools used in this research to analyze input-output time histories of a wind turbine structure, with a wide-band excitation, allow to obtain its modal state space representation. This representation reveals the internal behavior of the system, such as the interaction between its physical parameters. The techniques presented in this paper also allow researchers to obtain modal parameters, as well as frequency responses of a properly excited wind turbine structure immersed in wind noise. The use of two identification algorithms with the same, relatively simple numerical example, enables to compare the results obtained with the actual characteristics of the system modeled. Then, an example using the data generated by the ADAMS{reg_sign} model of the Micon 65/13 wind turbine structure is considered to illustrate additional elements to be included in the identification procedure for such a complex flexible structure.
