Scope

This standard specifies the modeling methods and networking requirements for dynamic simulation tests of relay protection systems in smart substations with voltage levels of 110 kV and above, as well as the test items, test methods, and judgment methods for test results. It is applicable to dynamic simulation tests of the network performance of protection systems composed of relay protection equipment, merging units, intelligent terminals, acquisition and execution units, and process layer switches in smart substations with voltage levels of 110 kV and above, which adopt analog quantity sampling and digital quantity sampling methods and are triggered by GOOSE signals. Network dynamic simulation tests of relay protection and related equipment in smart substations with voltage levels below 110 kV can be carried out as a reference, and relay protection network system tests can also be conducted as a reference.
