Abstract: At present, no circuit examination is required in acceptance of smart substation, which results in low efficiency in acceptance. In this paper, a testing tool of virtual circuit is developed in VB environment based on the uniqueness of the publisher in the process of GOOSE/SV packets handshaking. The operational errors of substation configuration description (SCD) could be checked out by comparing virtual circuits in SCD and virtual terminal table. Therefore, a scheme of dual acceptance is proposed for smart substation. By testing the virtual circuit before debugging, the defects can be reduced and the efficiency of acceptance can be improved. The proposed scheme was applied in the acceptance of Wujiazhuang 220 kV smart substation and was proved effective.

Key words: smart substation, virtual circuit testing, dual acceptance scheme, IEC61850
