An intelligent transformer station SCD file standardization degree verification method comprises the following steps of acquiring an SCD file being used by an intelligent transformer station, dividing the SCD file into a plurality of CID files according to IED names, analyzing the CID files to acquire configuration information of a secondary device of the intelligent transformer station, looking for an ICD standardized file corresponding to the configuration information of the secondary device in the ICD standardized file library, recording the name of the secondary device and the corresponding ICD standardized file name, making a content comparison between the ICD standardized file corresponding to the secondary device and the CID file, analyzing all the CID files and verifying whether the secondary device of the intelligent transformer station employs the ICD standardized file, outputting an intelligent transformer station SCD file standardization degree verification result, and writing the verification result into a result file and displaying the same. Verification of the ICD model standardization in the SCD file is simplified; and standardization degree verification result can be obviously viewed.
