Abstract: With the improvement of the intelligence and automation level of substations, the configuration file of intelligent substations has become the key to achieving automation work. This article introduces the key technologies and strategies of the visualization and control system for intelligent substation configuration files. Firstly, the importance of configuration files for smart substations in the power system and the limitations of traditional textual configuration files were outlined. Then, the visualization techniques of SCD files(system configuration files) and CCD files(client configuration files) were elaborated in detail, including their visualization methods, functions, and implementation steps. Finally, control strategies and processes for SCD files and CCD files were proposed to ensure the correctness, uniqueness, and consistency of configuration files, thereby improving the operational efficiency and reliability of smart substations.
