The invention relates to an intelligent checking method for the information data of a transformer substation monitoring information table. The method comprises the following steps: establishing a transformer substation monitoring information basic model; analyzing naming rules of equipment contained in the state grid monitoring information naming specification under different interval types and information output by various types of equipment; decomposing the monitoring information naming rules into interval data and equipment data; checking the content of the input data of the monitoring information tables of different data sources; outputting the difference between versions of different data source information tables, checking whether missing or increasing signals exist between differentversions of the monitoring information table or not, and traversing the information table in the system after the different versions of the information table or the acquisition information table is input; and an auditor recompiles or audits the information table by checking the difference result. According to the invention, the problem of information difference caused by different versions and different sources of the monitoring information table is solved, the working pressure of monitoring information table compilation personnel and auditing personnel is reduced, and the working efficiencyis improved.
