Abstract:

Substation configuration description (SCD) files describe the instance configurations and communication parameters of all intelligent electronic device (IED) in the station, communication configurations between IED, and virtual terminal connection information. In the debugging, reconstruction and expansion of smart substations, SCD files will be changed. But there is currently no convenient, intuitive and effective method to controlling SCD files. By analyzing the present situation of SCD file version control, a visual control function is developed on the intelligent station configuration tool. After verification of qualified SCD, all published SCD file tables are displayed. At the same time, the detailed differences in the content of different versions of SCD files can be reviewed, which achieves visual control of SCD file versions.
