Automatic generation of secondary circuit virtual connection in smart substation

智能变电站二次虚回路设计是智能站设计的主要工作,对智能站安全可靠运行具有重要意义。为提高虚回路配置效率,降低出错概率,提出了一种智能变电站二次虚回路自动生成的办法。该办法通过系统规范描述文件(SSD)中的间隔配置信息以及设计的"间隔连线表",基于共同信息模型,实现二次虚回路连线根据特征字自动匹配。此方法采用自动匹配过程,优于原来的人工连线,可以有效降低人工参与度,从而提高二次虚回路构建的工作效率和可靠性。该研究内容对于相关工程实践具有较好的借鉴价值。

The design of virtual secondary circuit is the main part of smart substation design work, which is of great significance to the security and trouble free operation of smart substation. To improve the efficiency of virtual circuit configuration and reduce the probability of error, a method of automation generation of virtual secondary circuit is proposed. According to the bay configuration information of the System Specification Description （SSD） and the designed ＂Connection Table of the Bay＂, based on the common information model, an automatic matching method of the virtual secondary circuit connection, which is based on the feature words, is achieved. Automatic matching process is adopted in this method, which is superior to the original manual connection as well as can reduce the manual participation, so that it can improve the working efficiency and reliability of the construction of virtual secondary circuit. And the content of the paper has a great reference value for the relevant engineering practice.
