Research on Automatic Generation Technology for Secondary Equipment of Security Measures of Smart Substation

In order to assist the secondary shift personnel to carry out the intelligent substation maintenance operation, a method of automatic generation of the second maintenance safety measures of intelligent substation is presented. Based on the maintenance safety mechanism of intelligent substation and the technical principle of ensuring maintenance safety, the types and functions of secondary safety measures are summarized. The maintenance equipment, accompanying equipment, associated operation equipment and maintenance boundary are defined. It includes design maintenance-stop base library, single equipment base library and maintenance safety measures filter rule base and it instantiates the base library by using the whole station system configuration file. The application and scope of "one-button" automatic double secondary maintenance safety measures and transparent display maintenance security measures are realized. Finally, the effectiveness of the method is verified by the pilot project, and it has good practicability.
