[Abstract]:Substation configuration description (SCD) file is an important data of intelligent substation equipment operation, daily operation and project management. Aiming at the engineering application problem caused by the high coupling of the internal relations of SCD model, the necessity and urgency of SCD model decoupling technology are expounded. Based on the expansion scenario, the physical decoupling scheme of SCD file interval is analyzed, and the interval modeling method based on system specification to describe (SSD) model is proposed to realize the secondary equipment integration into the interval. This paper focuses on the physical decoupling of the interval, defines the independent interval, the associated interval, the new interval in the extended scene, decomposes the SCD model into multiple interval files, uses physical isolation, and automatically analyzes the interval correlation relationship based on the SSD model. Configuration modification content layer signature comparison and other means to achieve independent interval isolation, avoid irrelevant interval error modification, reduce the intelligent substation expansion configuration, debugging, testing and other areas; According to the requirement of engineering application, the project configuration flow of SCD interval decoupling in extension scenario is given, and the main problems that need to be solved for the decoupling function of SCD interval are analyzed.
