With the continuous development and progress of science and technology,the intelligentized degree of the power grid is constantly strengthened.This makes the demand for automation of the substation increasing gradually.In the process of daily work,the conventional substation should combine the development demand and implement the automatic operation and maintenance mechanism and management standard.In the automation transformation project,the intelligent primary equipment such as electronic transformer and intelligent switch should be integrated effectively on the basis of communication specification to ensure that the differentiated intelligent electrical equipment can form the target of sharing digital information and interactive operation,complying with the development of the times and giving play to the basic advantages of modern substation.Based on this,the national Power Grid Corp has proposed to speed up the development of a unified strong smart grid with the characteristics of information,automation and interaction with the development of the UHV power grid as the backbone grid,the coordinated development of the power grid at all levels.This paper makes a comprehensive analysis of the background and significance of the research on the general automation project of conventional substations,studies the research status at home and abroad with reference to relevant literature,and on the basis of reviewing and summarizing the related analytical methods of conventional substation automation by means of literature research,discussion and case derivation.The research framework of effectiveness is to accurately and meticulously show the views of this article.In addition,based on the project of integrated automation upgrading and upgrading of 220 k V power transformer substation,the existing problems of 220 k V power substation are analyzed from several aspects,such as the main variable capacity load,the problem of the hardware facilities in the station,the organization of spare parts spare parts and the development planning requirements of the national network company.Secondly,the 220 k V library is designed.The overall optimization scheme of the integrated automation transformation of the substation has been digitalized to reconstruct the structure of the civil construction unit,substation station control layer,interval layer,process layer and communication network upgrading scheme.Again,the 220 k V Kumish substation I,Ⅱ bus voltage transformer merging unit and intelligent terminal upgrading are emphatically formulated.In the end,the comprehensive automation transformation scheme,operation strategy and transformation result of 220 k V power substation are analyzed and summarized from the dimensions of the comprehensive evaluation index weight and the one or two level weight index,which proves the application effect of the first equipment and the two equipment network.And feasibility. |
