The paper considers the experimental application of predictive vibration diagnostics technologies for a wind turbine. The work is carried out within the framework of the project on adaptation of the Vibropassport methods to wind turbines. These techniques allow high diagnostic resolution starting from first data measurement, and in the monitoring mode taking into account the history. Examples of the Vibropassport application for units of the specific wind turbine in field conditions are presented. The measurement set up and the structure of signals of an operating wind turbine’s units are discussed. The confirmed compliance of the wind turbine vibration structure with Vibropassport models allows using a set of standardized parameters of the Vibropassport for diagnostics of wind turbine units. Since the models have already been adapted for the diagnostic system, only the adaptation of algorithms and software for the calculation of parameters, including to the operating modes of the wind turbine, will be required. Considering that the fundamental suitability of Vibropassport models has been substantiated, only adaptation to the design features of specific type will be required to develop diagnostic systems for various types of wind turbines.
