基于标准中间过程文件的SCD版本比对的优化研究

Optimal research of SCD version comparison based on the standard middle process files

智能变电站的建设中,链路参数、虚端子的修改等原因形成不同阶段的SCD文件版本。对基于SCL的比对方法和可视化方法进行了优化,比对方法提出基于中间文件方式,可视化方法提出了四层人性化展示方式。通过提取SCD文件的关键配置信息,形成各IED的标准中间过程文件。从IED、CRC、链路、链路参数及虚回路四个层次,以可视化方式自顶向下逐层实现SCD文件的版本比对,降低了可视化比对过程中对内存和CPU主频的要求,提高可视化的解析和展示效率,方便了运维人员对SCD版本的可视化管理。

In the smart substation construction, SCD file will form different stage versions when communication parameters and virtual terminal are modified. This paper optimizes the comparison method and visualization method based on SCL. It proposes the comparison method based on standard middle process file and visualization method with four layers of humanized display. Through the extraction of different SCD files with key configuration information, from four level with IED, CRC, link, link parameters and virtual circuit. It implements the SCD file versions comparison layer by layer from top to down in a visual manner. It reduces the requirement on memory and CPU main frequency in the process of visualization comparison, improves the analysis and display efficiency of visualization, and provides convenience for operation and maintenance staff to carry out visualization management for the SCD file versions.
