IEC-61850 use in central relay protection and automation network systems

Abstract

The authors have developed design principles for physical models of the smart grid system. This system includes physical models of measurement units, control and protection devices, and provides data transfer in compliance with IEC 61850. The authors propose to use GOOSE-messages to transmit measurement results from the measuring current and voltage transformers located at remote nodes of energy network. The results can significantly reduce data transfer rate demand of the central relay protection and automation network systems.
