Management Information System For Transformer Equipment Status Overhauling

With the fast development of the power grid construction, the status overhauling is bound to take the place of the traditional periodical overhauling. To analyze the status of equipment correctly is the base to realize the status overhauling. In this thesis, the author argues that a certain test or detect can only get the partial information of equipment status, so from the viewpoint of information system, the data integration, and the test, association, estimate and combination would be needed to reach the accurate estimate of the status. The comprehensive analyzing (CA) method for the status estimate of transformer equipments based on the theory of information integration is brought forward, and proved the practicability of the method by the example of oil-marinated power transformer.There are three parts in this thesis. The first summarizes the meaning of CA for equipment status, brings the method for the diagnosis to the malfunction of transformer equipment, and elaborates the acknowledge and tools of the CA for equipment status. The second takes the oil-marinated power transformer as an example, and elaborates the CA method for the status estimate of transformer equipments based on the theory of information integration. The third takes the actual status of Jining Power Bureau as an example, sets up the overhauling MIS of transformer equipments with the proposed method.Zhang Cunming(Electrical Engineering)Directed by Prof. Li Gengyin, Su Jianjun...
