This invention discloses a method and system for locating faults in a wind turbine drivetrain. The method includes: constructing a dual-flow graph neural network model containing two paths: physical flow and latent flow. The input to the model is the features of each node constructed based on multi-channel vibration signals, and the output is an enhanced node representation. The physical flow and latent flow are used to extract explicit and implicit structural correlation features between nodes, respectively. During the training phase, physical consistency constraints are introduced to suppress unreasonable spatial jumps in the implicit correlation structure. During the model operation phase, a historical sample management mechanism based on sample information is combined to enable the model to continuously adapt to new fault categories without forgetting existing knowledge. Finally, the contribution of each sensor node is quantified based on the change in the original discriminant response to generate a fault location result consistent with the drivetrain topology. This invention can achieve refined and interpretable fault location in wind turbine drivetrain scenarios with small sample sizes and incremental learning.

A method for mitigating vibrations on a wind turbine generator (100). The method includes providing a drone (10) carrying an airflow disruption line (6) on a spool (14), securing a first portion (8) of the airflow disruption line (6) at a first attachment position on the wind turbine generator (100), deploying the airflow disruption line (6) around at least one part of the wind turbine generator (100) by flying the drone (10) around the at least one part from the first attachment position to a second attachment position on the wind turbine generator (100), and securing a second portion (9) of the airflow disruption line (6) to the second attachment position. The method enables efficient installation and removal of vibration mitigation devices on wind turbine generators (100) same with minimal manual intervention, reducing downtime and maintenance costs while effectively mitigating various types of vibrations in wind turbine structures.

A method for manufacturing a structural component of a blade segment for a rotor blade (28) includes providing a mold (150) of the structural component having an outer wall (152) that defines an outer surface of the structural component. The method also includes laying up one or more fiber layers (154) in the mold (150) so as to at least partially cover the outer wall (152). As such, the fiber layer(s) (154) form the outer surface of the structural component. Further, the method includes providing one or more metal mesh layers (156) having one or more ends. Moreover, the method includes providing a cover material (160) to the end(s) of the metal mesh layer(s) (156). In addition, the method includes placing the metal mesh layer(s) (156) with the covered end(s) atop the fiber layer(s) (154). Thus, the method includes infusing the fiber layer(s) (154) and the metal mesh layer(s) (156) together via a resin material so as to form the structural component.

This invention relates to the field of wind power generation technology, specifically to an in-workshop testing system for the yaw system of a wind turbine generator set. After assembling the yaw system and yaw bearing, the system controls the start / stop, speed, and direction of the yaw motors via a yaw test cabinet, enabling testing of multiple yaw motors within the yaw system and improving its reliability. The invention also relates to an in-workshop testing method for the yaw system of a wind turbine generator set. This method controls the start / stop, speed, and direction of the yaw motors via a yaw test cabinet, acquires the current signals of each yaw motor, obtains the stress conditions of each yaw motor based on these current signals, and then adjusts the tooth clearance between the gears of the yaw gearbox and the gears of the generator set bearings based on these stress conditions. This results in a more even distribution of load across the multiple yaw motors in the yaw system, further improving the reliability of the yaw system.

A method for fabrication of a composite component, e.g. wind turbine blade, comprises forming a composite structure within a mold, the composite structure including a resin dispersed throughout the fibers in the composite structure and applying a surface treatment, e.g. sanding, to at least one region of the composite structure. A Fourier Transform Infrared (FTIR) spectrometer is employed to irradiate the treated surface area with infrared light; and determining the amount of infrared light absorbed in the treated area of the composite structure to measure the chemical bond (distribution efficacy, chemical composition, and cure state) of the composite product. Calibration models for a variety of materials are made using a partial least squares 2-variable regression. These calibration files incorporate spectrum from samples of varying resin-hardener mix ratio, and at varying degree of cure. After library comparison confirms the material, the device automatically selects the correct calibration file, ensuring accurate results.
