Transformer health state assessment method and system based on multi-dimensional incidence relation

The invention provides a transformer health state assessment method and system based on a multi-dimensional incidence relation, and the method comprises the steps: collecting the state quantity data of a target transformer and adjacent transformers, and constructing a multi-transformer state quantity matrix; on the basis of the state quantity data of the target transformer and the adjacent transformers, the incidence relation between the state quantity data of each transformer is calculated; based on the multi-transformer state quantity matrix and in combination with the association relationship between the state quantity data of each transformer, calculating the multi-dimensional association relationship between the target transformer and the adjacent transformer; based on the multi-dimensional incidence relation between the target transformer and the adjacent transformer, the health state grade of the target transformer is obtained through a transformer health state evaluation model; according to the method
