The invention discloses a historical inversion method and system for a secondary circuit of an intelligent substation. The method comprises: collecting and storing state information related to the secondary circuit; querying and arranging to obtain effective historical state information related to the secondary circuit; initializing a historical secondary circuit visualization diagram, and displaying historical secondary circuit remote signaling state change information in a list; and inverting and displaying a historical secondary circuit. According to the invention, the historical state datarelated to the secondary circuit of the intelligent substation is stored and inquired, and the historical state and change of the secondary circuit are inverted in the form of graphs and lists, so that the visual historical tracing of the secondary circuit is realized. The historical state of the secondary circuit of the intelligent substation can be rapidly mastered and the historical fault of the secondary circuit can be accurately positioned so that the visualization and fault positioning functions of the secondary circuit of the intelligent substation can be perfected, the technical meansof intelligent operation and maintenance of the secondary equipment of the intelligent substation can be expanded and safe and stable operation of the intelligent substation can be further guaranteed.
