摘　　要：目前,含智能化变电站完整模型的配置描述文件及其它相关配置文件的标准化管控方案仍未见报道。实施智能站配置文件的全流程管控系统,建立基于标准描述语言的模型标准库,可以实现对智能化变电站配置精细化、标准化管理。不断完善模型检测能力,从而给智能变电站的二次设备间互联、互换、互操作提供保障。并且,给智能变电站的验收及运行维护提供基础,给基于信息模型的一些智能分析及应用提供支持。现从智能变电站中SCD文件的重要性出发,对智能变电站SCD管控系统进行研究,包括SCD管控的重要性、SCD管控的技术和管理现状。进而建立智能变电站中二次设备和虚拟二次回路的简化模型和CRC校验实现方法和管控方案。最后,在变电站SCD管控系统的总体方案设计中,引入改进的基于位置的文本文件对比算法,用于比较SCD文件,有利于现场工作人员快速高效地获取信息,从而实现管控的目的。Up to today, we have yet to see any report on the standardized management and control scheme of the configuration description file and other related configuration files of the smart station. Implementation of the whole process management and control system of the smart substation configuration file and establishment of the model standard database based on the standard description language facilitate the fine and standardized management of the smart substation configuration. Constant improvement of the inspection capability of the model helps to guarantee the interconnection, exchange and interoperahility of the secondary equipment of the substation and provide the basis for the acceptance and operation and maintenance of the substation and support for some intelligent analysis and application which are based on the information model. Starting from the importance of the SCD file of the smart substation, this paper studies the SCD management and control system of the smart substation, covering the importance of the SCD management and control system, the current situation of the SCD management and technology. Furthermore, the simplified model of the secondary equipment and the virtual secondary loop in the smart substation and the CRC verification method and the control scheme are established in this paper. Finally, the improved location-based text file comparison algorithm is introduced into the overall design of SCD control system of the substation for comparing SCD files, which helps the on-site staffs to gain the information quickly and efficiently so that the purpose of the control can be realized.
