| Abstract: | Based on historical operating data of 500kV transformers provided by Yunnan Power Grid Corporation,a fault di-agnosis model for 500kV transformers was established,with the technology of Bayesian network and data mining.The theory of importance measure was also introduced to analyze the influence factors of transformer fault.Finally,the real -time oper-ating records of practical transformers were used to verify the effectiveness and usefulness of the proposed model. |
