Panjin South Central Research And Application Of Intelligent Substation220kV

Construction, infiltrate into electricity production and application of each link, intelligent substation is an important part of smart grid, it represents the substation of the new technology development direction, is the core of each link in a ring. Based on IEC61850specification are studied in this paper the practical application of intelligent substation, combining with the design of ’file liaoning south ring220kv smart substation project, through the analysis of and research into the technology application of intelligent substation, through the planning scheme, control equipment selection, selection of technical plan, find the intelligent substation the best technical and business solutions, and through the design, implementation and feedback, to verify the intelligent substation than traditional substation technology advanced, reliability, erified the rationality of the preliminary technical proposal and configuration, as well as the problems discovered in running process analysis and research to find out a solution.This paper discusses the technical characteristics and application of intelligent substation, this paper expounds the intelligent substation main technology application, electronic transformer, merging unit, intelligent terminal, etc.), communication network part (IEC61850statute, chicago-brewed GOOSE, station control layer, spacer layer, process, etc.), advanced application functions, etc.; Analysis of the220kv smart substation configuration principles and function requirements; According to the characteristics of intelligent substation and the actual situation, to set up a file the south ring intelligent substation equipment configuration, a file to complete the south ring network architecture of intelligent substation; Intelligent substation is analyzed three kinds of construction patterns, finally determined the panjin south ring intelligent substation network architecture and intelligent substation construction mode; A file through the south ring intelligent substation design, construction and parameter analysis, verified the feasibility and rationality of design scheme in advance; Operation shows that intelligent substation than traditional substation to be advanced, has a high reliability.
