| Abstract: | Combined with the Rogers ratio method,an insulation fault diagnosis model based on adaptive PSO and LS-SVM is presented for traction transformer.It adjusts the inertia weights to accelerate the training speed according to the swarm convergence and individual fitness.The matrix of LS-SVM is solved through the adaptive PSO to avoid the inverse solution for memory saving.In order to quickly and accurately distinguish 12 insulation faults,12 LS-SVM classifiers based on adaptive PSO are built.Tests on 600 groups... |
