Abstract: The standard IEC 61850 defines an abstract model of sampled value (SV) transmission, which is applied in SV transmission and the related services. In order to meet the flexibility and interoperability requirements on substation automation systems and smart devices proposed by this standard, based on the study of information model connotation in standard IEC 618 50, this paper introduced the information model and mapping of merging unit, and constructed the SV transmission model of merging unit. By preconfiguring the SV control block, the SV transmission was conducted on the basis of IEC 618 50-9-2 and the flexibility of merging unit’s configuration information was analyzed. The experiment verifies the validity of the information configuration.
Key words: merging unit; sampled value transmission model; IEC 61850-9-2; flexible configuration
