Design And Research On Secondary System And Intelligent Application Of 110kV Yangwu Intelligent Substation

With the development of society,the demand for stable power supply is gradually improved,and the concept of intelligent substation emerges as the times require.Compared with the traditional substation,intelligent substation has the characteristics of whole station information digitization,communication platform networking,information sharing standardization and advanced application interaction.However,in terms of the current domestic development,due to the immature production process and application technology of primary equipment,the construction focus of domestic intelligent substation is mainly reflected in the construction mode of secondary system.Taking the 110 k V Yangwu substation of the first OS2 Smart Substation of China Southern Power Grid Corporation as an example,this paper theoretically analyzes and designs the construction mode of the secondary system of the smart substation from the following aspects.(1)This paper summarizes the shortcomings of traditional substation construction,and discusses the disadvantages of traditional substation secondary development system.(2)This paper introduces the IEC61850 global power system automation standard and the construction method of the secondary system of intelligent substation in detail,and discusses the advantages and disadvantages of intelligent substation at this stage.(3)Based on the actual operation and maintenance data of 110 k V Yangwu intelligent substation,this paper summarizes the construction methods of the secondary system of intelligent substation,analyzes the implementation methods and advantages and disadvantages of each functional module,so as to provide data support for the development of secondary system of intelligent substation in the future.(4)Through the design and research of intelligent application of 110 k V Yangwuintelligent substation,the underlying design logic,actual requirements and industry standards are analyzed and studied theoretically and practically.The technical characteristics and shortcomings of each intelligent application are analyzed,which provides data support and theoretical support for the comprehensive implementation of intelligent application module of intelligent substation in the future(5)Finally,through the actual operation and maintenance strategy of 110 k V Yangwu intelligent substation,this paper deeply analyzes the energy-saving and efficiency increasing effect of intelligent substation in the new era,and summarizes the deficiencies found in the operation process,so as to provide experience guarantee for the comprehensive construction of intelligent substation in the future.
