14 Analysis on the System Configuration of Digital Substations

Abstract

In accordance with the definition of the IEC 61850 standard, a digital substation is hierarchically distributed and divided into the process layer, the spacer layer and the station layer. On the basis of the analysis of its structure and function, this work is focused on the configuration of different layers and that of the dual bus wiring electronic transformer and merged unit, as well as the GOOSE network solution under the relay double configuration.
