Damage Identification Method of Wind Turbine Generator System Blades Based on Image Processing Technology
Bibliographic record
Abstract
In order to ensure the efficient operation of wind turbine generator system (WTGS) and the safety and stability of wind farms, it is necessary to promptly detect and repair the blade damage.The traditional methods of detecting WTGS blade damage mainly rely on manual inspection, which is time-consuming, laborious, and has low accuracy.Therefore, it is of important practical significance to study the damage identification method of WTGS blades based on image processing technology.Due to the drawbacks of existing methods, this research aimed to study the damage identification method of WTGS blades based on image processing technology.A method of expanding blade damage samples based on the improved Deep Convolutional Generative Adversarial Networks (DCGAN) was first proposed, which generated a high quality damage image sample set to improve the classification performance of the deep learning model.For the problem of damage images often affected by noise and environmental factors in practical scenarios, it was solved by morphology-based blade damage edge enhancement.In addition, the blade damage state evaluation and classification process based on multifractal spectrum (MFS) was provided.Finally, the experimental results verified that the proposed algorithm was effective.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
