Research On The Design Of 110kV Intelligent Substation For Beijing New Airport

Promote clean energy use,ensure energy security and stability,improve energy efficiency has become a new trend in today's energy development.Intelligent substation is an important intermediate link in the smart grid.The technical level of the intelligent substation directly affects the construction level of the smart grid.Therefore,the intelligent substation design system research,the formation of advanced and reasonable design,smart grid and intelligent substation construction is of great significance.Intelligent substation on the one hand to improve power supply reliability,on the other hand by improving the degree of intelligent equipment to reduce the late operation and maintenance investment.According to the plan,the Beijing New Airport will build two 110 kV central substation,according to the intelligent substation standards for design,plans to be put into operation in 2019.Civil airport electricity is a primary load,which has great safety,reliability and stability for power supply protection.Therefore,it is very important to study 110 kV intelligent substation in Beijing New Airport.The main work of this paper is as follows: Firstly,the development background of smart grid and intelligent substation is introduced,and the research status of domestic and foreign research is introduced.Secondly,the concept and main technology of intelligent substation are expounded.Characteristics of the intelligent substation several core technologies were studied,including: IEC 61850 standard content and characteristics of the network communication structure,integrated monitoring system for the subsequent one or two program to provide the basis for;This paper focuses on the analysis of the network communication structure of intelligent substation,compares and analyzes the characteristics of various network structures,selects the most suitable network structure,and analyzes the characteristics of the network structure of the intelligent substation.At the same time,Compared with the power substation of the intelligent substation and the traditional substation,the advantages of the integrated power system of the intelligent substation are analyzed,and the design content is improved.Finally,the design and research of the 110 kV intelligent substation are summarized and the research direction is put forward.
