摘要
综合运用装置过程层配置循环冗余校验(CRC)码在线管控、变电站配置描述(SCD)文件虚回路配置信息比对和SCD文件虚回路可视化校验等方法,可有效确定SCD文件升级时需同步升级配置的装置。对比分析了变电站二次系统硬回路和虚回路的特点,提出并论证了SCD文件管控策略的完备性。以母线保护为例,分析了智能变电站扩建工程中SCD文件的管控方案。
By comprehensive use of online cyclic redundancy check（CRC） code control,comparative analysis for configuration of the virtual circuit and visual check for the virtual circuit of substation configuration description（SCD）file,the devices whose configuration should be upgraded synchronously with SCD file can be determined.Through comparative analysis of the characteristics of hardware circuit and the virtual circuit of the secondary system in the substation,the completeness of the SCD file control strategy is proposed and proved.In the case of the busbar protection expansion project,the control scheme for the SCD file is analyzed.
