Abstract

IEC61850 is anew generation of international standards based on the general network communication platform for substation automation system.This standard provides the basic theoretical basis of the realization Smart Substation.In Smart Substation building,the use of digital communication interface of the Intelligent terminal as the primary equipment is the ideal solution to achieve process layer device intelligent.

This paper first introduces the research background of the Intelligent terminal and conducts research of Intelligent terminal related  products at home and abroad.On the basis of the analysis of the Intelligent terminal features, the IED information  model of the Intelligent terminal is constructed in accordance with IEC61850 modeling method. This paper has done a preliminary test. Then, software designed based on this hard ware platform,and on the function to achieve several key issues to be explored. GOOSE communication principles and procedures of implementation are analyzed.

Through the GOOSE communication packet capture analysis to verify the Intelligent terminal can achieve the technical specifications and functional requirements in the actual project.IEC6185O-based Intelligent terminal design on product prototyping and later put into operation laid the foundation has practical value in the power industry.
