Research On Intelligent Transformation Of Conventional Substation

Intelligent substation is an important part of smart grid.High reliability of equipment is the foundation of strong substation,comprehensive analysis,automatic coordinated control is the key to the intelligent substation.Device information digitalization,function integration,compact structure,state of maintenance are the development direction,and operational efficiency is the ultimate goal.First of all,this paper introduces the research status of intelligent substation at home and abroad,and puts forward the intelligent transformation of the existing problems of the traditional substation,the significance and content is explained in this article.Next,based on the intelligent technical specifications,the traditional 110 kv substation is retrofitted by the reconstruction scheme of intelligent design,which is on the improvement of substation as primary equipment intelligent and secondary equipment networked.Then,the key technologies of intelligent substation for advanced use are piloted actively,and some modification embodiments are made in the station auxiliary systems to get accumulated practical experience for subsequent reconstruction project.Finally,this paper forms a typical experience with the summary of intellectualized reconstruction of key technical points and execute solution,and puts forward the corresponding countermeasures according to the existing technical risk points.This paper summarizes the design construction,operation and maintenance experience for the subsequent construction of Smart Substation in Jiangxi area,to provide technical reference the engineering practice and experience transformation by 110 kv substation intelligent transformation project.
