220kV智能变电站智能电子设备按支路整改难点及解决方案

Difficulty and Solutions on Rectification by Branch of Process Level IED in 220 kV Intelligent Substation

通过对220kV智能变电站过程层智能电子设备按支路停电整改难点的分析,提出新旧设备能力描述文件兼容化处理、过渡文件的配置与使用、兜底式虚端子互传等3个解决方案,为智能变电站过程层智能电子设备整改工作思路提供了借鉴。

According to the analysis of difficulty on process level IED rectification by branch in 220 kV intelligent substation, some solutions, such as original and new ICD model compatible technology, configuration and application of transitional SCD and ICD file,catch-all test of virtual terminal, are summarized and proposed in this article, which can provide some reference for intelligent substation IED rectification.
