摘要:
      变电站配置描述(SCD)文件是智能变电站设备运行、日常运维、工程管理依赖的重要数据。针对SCD模型内部关系高度耦合带来的工程应用问题,阐述了SCD模型间隔解耦技术的必要性和迫切性;面向扩建场景,分析了SCD文件间隔物理解耦方案,提出了基于系统规范描述(SSD)模型的间隔建模方法,实现二次设备归集到间隔中;重点研究了间隔物理解耦,定义扩建场景中无关间隔、关联间隔、新增间隔,将SCD模型分解成多个间隔文件,采用物理隔离、基于SSD模型间隔关联关系自动分析、配置修改内容分层签名比对等手段,实现了无关间隔隔离,避免无关间隔误修改,缩小智能变电站扩建时的配置、调试、测试等范围;结合工程应用需求,给出了扩建场景SCD间隔解耦的工程配置流程,并分析了当前针对SCD间隔解耦功能尚亟需解决的主要问题。
Abstract:
      Substation configuration description(SCD)file is important data for equipment operation, routine operation and maintenance, project management in smart substation. In view of the engineering application problems brought about by the high degree of coupling in the SCD model, the necessity and urgency of the decoupling technology about the SCD model is expounded. For the smart substation expansion project, the scheme of SCD bay physical decoupling is analyzed, and the bay modeling method based on the system specification description(SSD)model is put forward, which makes secondary devices grouped into the bay. The SCD model is decomposed into a number of bay files mainly by physical decoupling. And the unrelated bay, the correlation bay and the new bay are defined for the smart substation expansion project scenario. By means of physical isolation, automatic analysis of the relationship between the bay based on the SSD model, hierarchical signature comparison configuration modification, the unrelated bay is isolated and modification errors are avoided. The area of the configuration, debugging and testing, etc, is reduced for the smart substation expansion project. For engineering application requirements, the configuration process of SCD bay decoupling is given for the smart substation expansion project. Current main problems demanding prompt solu-tion for SCD bay decoupling are analyzed. This work is supported by State Grid Corporation of China.
