Research of Scheme for Mapping Between Virtual and Real Link and Fault Diagnosis in Smart Substation Based on SPCD

Aiming at the problem that description of physical link information in SCD file is blank and physical link cannot be quickly located by alarm information of virtual link failure in operation and maintenance of substation, this paper proposes to extract physical link information from SPCD file, extend physical link model in SCD model, and construct mapping between virtual-real link in smart substation. This paper provides technical support for the visualization of physical circuit of substation and a feasible scheme for fast fault location.
