Smart Substation Configuration File Management and Verification Technology and System

Smart substation configuration files carry key information and parameters such as primary equipment model and electrical topology, secondary equipment configuration and virtual circuit connection. Configuration errors can easily lead to abnormal operation and even incorrect protection actions. The management and verification of configuration files are essential to the safe and stable operation of substations. In the whole process of configuration and life cycle of smart substation configuration files, due to lack of management and verification measures, the correctness and uniqueness of configuration files are difficult to guarantee. This article introduces the typical configuration file management process of State Grid Corporation, proposes measures such as configuration file version difference comparison, legality check, integrity check, consistency check and normative check, and designs a configuration file management and verification system, Can realize the effective management and verification of configuration files.
