Abstract: In response to the current issues of the SCD file integration process relying heavily on manual operations, low integration efficiency, and the integration level of SCD files being affected by the technical capabilities of the staff, an SCD file automatic integration tool based on AI agent recognition of site features has been designed. This tool consists of three parts: the intelligent recognition module of site features, the feature tag set processing module, and the expert experience library matching module. It can achieve the functions of extracting and classifying the features of substation sites, generating typical bay configuration schemes, extracting ICD file information, and integrating instance virtual circuits. The verification results of the engineering case show that this solution has a high integration efficiency and strong application adaptability, and it is an effective path for the future standardization of SCD file integration in intelligent substations.
