APPLICATION RESEARCH ON FAULT DIAGNOSIS OF DOUBLE FED WIND TURBINE BEARINGS BASED ON IMPROVED GENERATIVE ADVERSARIAL NETWORKS
Aiming at the problem of the low fault diagnosis accuracy caused by the lack of fault samples for the rolling bearings of doubly fed wind turbines under normal conditions for a long time
an improved generative adversarial network fault diagnosis method based on expanding high-quality fault samples and using dual feature extraction was proposed. Firstly
a finite number of rolling bearing fault samples were expanded through a Wasserstein type generative adversarial network with maximum mean discrepancy and penalty constraints. Secondly
based on the dual feature extraction model
the time-frequency converted temporal features and local features were extracted separately. Finally
the fault diagnosis of the rolling bearing balance data was completed through a classifier. The standard dataset and test results show that the proposed method improves the fault diagnosis performance while lacking fault samples.
