Intelligent substation virtual test method based on minimum test system

The invention aims to provide an intelligent substation virtual test method based on a minimum test system. The intelligent substation virtual test method comprises the following steps of: S1, constructing a substation factory maintenance platform according to a substation consistency guarantee principle; S2, constructing an intelligent substation minimum test system according to the substation consistency guarantee principle; S3, testing virtual equipment in operation, maintenance, reconstruction and extension through the minimum test system in the step S2; S4, performing relay protection testing of the intelligent substation, allowing a user to select an inspection category in the minimum test system, read a configuration file corresponding to the inspection category, judge the operationquantity and type contained in each detection item and end the inspection after waiting for an inspection time interval; and S5, carrying out off-line test on on-site maintenance safety measures of the intelligent substation
