Base On The IEC61850 Of Zhiyan 500kV Digital Power Grid Substation's Configuration Of Relay Analyse And Discuss

The continuous development of network and the electricity market in-depth reform require the economic security of grid operation and quality supply continuously improve, the substation transmission as a source of information and implementation of terminals of distribution system, require more and more information and integrated control. Digital, information technology and information model of the requirements of more and more pressing, digital Substation becomes substation direction of development.This paper takes the Zhiyan 500 kV Digital Power Grid Substation for example, introduces a digital substation of the basic knowledge. The main contents of this paper are:First, the digital substation construction scheme, engineering application model, network mode and the configuration of relay are discussed; Second, discusses the dissimilarity of protective relay between 500kV Zhiyan digital substation and traditional substations by comparing this substation with traditional one; Third, The progress of condition-based maintenance of digital substation based on IEC 61850 are analyzed. This paper also expatiate and analyse the intelligence alteration of Zhiyan 500 kV Digital Power Grid Substation.
