| Abstract:In view of the poor readability of Substation Configuration Description file (SCD) and the lack of standardized and effective control tools, this paper builds a set of visualized smart substation SCD file management and control system with user rights management function based on the modular design idea and by using the software of QT 4.8.4. The system has SCD file visualization, SCD file control and SCD file comparison features. In SCD file visualization module, the DOM tree structure is used to parse the SCD file to make the contents of the SCD file more hierarchical. In SCD file management and control module, it can realize the centralized management of SCD files of multiple smart substation in the area and has a series of functions such as uploading, archiving, verifying and visualizing SCD file. In SCD file comparison module, a location-based file text comparison algorithm is used to obtain the change of the SCD file, in order to clarify the situation that the device configuration information changes due to the SCD version upgrade and compare the SCD file. At the same time, it develops SCD visual handheld devices to facilitate debugging and operation and maintenance personnel to view SCD files anytime and anywhere.
