Abstract:In order to accurately judge whether a transformer winding has faults and ensure the reliability of power supply of the transformer, a method of transformer winding fault diagnosis based on BAS-SVM is proposed. It uses an SVM as the classifier of the transformer winding deformation degree, and optimizes the kernel function and penalty factor of the SVM by using a beetle antennae search algorithm. The BAS-SVM is trained by artificial experience to ensure that the algorithm has a high accuracy of fault diagnosis. In order to compare the advantages of the BAS-SVM algorithm in this application, a Modified Particle Swarm Optimization (MPSO) is also used to optimize SVM. The simulation results show that the fault diagnosis accuracy rate of the BAS-SVM algorithm is 10% higher than that of MPSO-SVM algorithm. Finally, the effectiveness of the BAS-SVM method on transformer winding fault diagnosis is verified by an example.
