摘要:

智能变电站SCD文件构成了二次系统的核心组成部分。针对现阶段SCD应用过程中存在的问题，结合江苏500 kV高邮智能变电站，提出了基于全模型SCD的可视化管理在线技术方案。实现了智能变电站二次系统“图实相符”的可视化应用，及保护二次系统异常状态的智能诊断。印证了“源端数据维护”机制的可行性，为智能变电站各种高级应用提供了可借鉴的技术路径。

Abstract:

SCD plays the key role within the secondary circuits of a smart substation. This paper illustrates present situation of SCD application and proposes an online-visualized technical solution based on complete SCD model associated with 500 kV Gaoyou substation. It is realized that the application of "physical connection matching picture" for substation secondary circuits as well as smart diagnostic of an abnormal situation for secondary circuits. Furthermore, the mechanism of "source data maintenance recommended for the advanced application of smart substation.

Key words: smart substation relay SCD visualization smart diagnostic
