Summary: | For a long time, the fault diagnosis and assessment for power transformer is a quite complex and difficult problem. In this paper, we propose a transformer fault diagnosis method based on fuzzy theory. The dissolved gas concentrations are set as the inputs of the system, and a fuzzy system group is appLied to build the intelLigent diagnosis system. The parameters of the system, including the input dimension, output dimension, and the membership functions, can be set up in whole or separately in the system. To test the effectiveness of the proposed method, it is appLied to the practice dataset. The experiment results show that the fuzzy system group improves the accuracy of assessment greatly compared with fuzzy system and BP neural networks. Also, the knowledge system of power transformer fault diagnosis can be built up completely by the proposed method. |
