The invention discloses an integrated platform of configuration protection and engineering configuration of a digital transformer substation, which is characterized by comprising an imaging device function configuration module, an IEC 61850 modeling configuration module and a secondary equipment networking module of a transformer substation, wherein the imaging device function configuration module is used for imaging configuration, automatically generating protection based on the C language after configuration and simultaneously generating a device function description configuration file provided for the IEC 61850 modeling configuration module to use; the IEC 61850 modeling configuration module is used for managing configuration files of the whole transformer substation and carrying out secondary instantiation and private configuration mapping through the device function description configuration file output by the imaging device function configuration module; and the secondary equipment networking module of a transformer substation is used for finishing the GOOSE communication configuration of a single device or devices of the whole station and outputting a GOOSE dummy terminal signal list. The invention can quickly meet different requirements of different users to realize the protection of flexible configurations and quick configuration so as to improve the on-site engineering debugging efficiency of the digital transformer substation.
