【Abstract】 With the increasing scale of wind energy equipment in various countries,the operation and maintenance of wind turbine has become a research hotspot. In this article,we propose a fault diagnosis model based on Apriori algorithm and convolutional neural network(CNN)to address the problem of fault diagnosis of wind turbine. This model combines k-means and Apriori algorithm for feature selection and verification so as to reduce the dependence on expert experience;the fault diagnosis model is constructed by CNN. The experiment was conducted with supervisory control and data acquisition(SCADA)data of real wind farm,and our proposed model was compared with other models including accuracy,accuracy and other indicators. The results show that compared with other models,the accuracy of this model is higher and the overall effect is better.更多还原
