摘要
A data driven diagnosis method based on acceleration signals for the gearbox in wind turbine is proposed, which on the basis of the grey wolves optimised variational modal decomposition (AGWO-VMD), normalized composite multiscale dispersion entropy (NCMDE) and long short-term memeory (LSTM), the gearbox faults diagnosis is realized rapidly. Firstly, the discrete signal in time domain is converted to angular domain. Secondly, AGWO-VMD algorithm is used to decompose the signal adaptively, and NCMDE algorithm is used to extract fault features as feature vectors from both original and decomposed signals. At last, the LSTM model is used for intelligentive classification of feature vectors. The proposed method is validated by 100 groups of data under 6 types of faults collected from WTDS, and the result shows that, it can recognize the right type of gearbox's fault rapidly and effectively. © 2022, Solar Energy Periodical Office Co., Ltd.
