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.
