Abstract

In view of such problems of the transformer oil dissolved gas analysis（DGA）pentagonal interpretation tool as relying on field experience

low accuracy and too absolutist classification boundary

the fault diagnosis method of the transformer based on quantum-behaved particle swarm optimization support vector machine（QPSO-SVM）and DGA pentagonal interpretation tool is proposed. First

the centroid coordinates of the relative percentage of Duval Pentagon1 characteristic gas and the centroid coordinate of the Mansour Pentagon characteristic gas are calculated based on the data of dissolved gases in transformer oil. Then

QPSO-SVM-Duval Pentagon 1 and QPSO-SVM-Mansour Pentagon fault diagnosis models of transformer are constructed. Finally

the fault diagnosis methods for different transformers are compared and analyzed. The simulation results show that the accuracy of QPSO-SVM-Duval Pentagon 1 and QPSO-SVM-Mansour Pentagon fault diagnosis method for transformer is higher than 95.00%. Compared with QPSO-SVM-Duval Pentagon 1

QPSO-SVM-Mansour Pentagon 1 has high accuracy and complex calculation. And compared with the conventional DGA pentagonal interpretation tool and the traditional QPSO-SVM fault diagnosis method for transformer

the proposed method is more accurate.
