To meet the requirement of networking transmission and information sharing in the new generation of smart substation, the application of the power switch is studied. This paper describes the power switch architecture in detail, also proposes an application scheme utilizing the power switch in building process layer communication system of smart substation. Then a simulation system is built to focus on the SV and GOOSE transmission performance, also the SV transmission dispersion and GOOSE transmission delay time are tested using network message recorder and analyzer. The result shows that power switch can be used in building process layer network of smart substation to meet the networking application requirements.
