摘要
Abstract
Currently,the fault diagnosis of transformer did not adopt overall judgment of various state information. Starting with the basic conception and evidential fusion reasoning method of Dempster-Shafer evidential theory, multi-fault characteristic information fusion diagnosis frame of transformer is constructed. A new approach to fault diagnosis based on multi-information fusion of fault characteristic, Dempster-Shafer evidential theory and basic probability assignment contribution method is proposed. An example is present, it is shown that the method is good to improve the reliability of the diagnosis and decrease the uncertainty markedly.关键词
