110kV数字化变电站变压器测控保护

第页110kV digital transformer test and control protectionAbstractToday,with the rapid development of digital technology,the development ofsubstation is becoming more and more digital and the level of automation isbecoming higher and higher.Digital substation converts analog information intodigital information in traditional substation,and builds on IEC61850 communicationstandard,which overcomes many shortcomings of automatic substation.Therefore,the digital substation principle,design process learning,the future may participate inrelated work,further research and so on have an important role.This paper first introduces the significance and development trend of digitalsubstation,and then describes and summarizes the content and principles of thespecific design of digital substation.The main contents of this design are:relatedtheoretical study of digital substation;familiar with digital substation design process;the two part design of digital substation according to the two key learning;equipment selection of principle;design drawing recognition,analysis of circuitbreaker circuit logic,terminal to have a clear understanding of the structure;and thecomposition of digital substation;have a very detailed understanding of the digitalsubstation two part of the design process and content,including protection andcontrol,measurement,group screen,telecontrol communication device and otherparts;and for the selection of the two device,the related principle of learning.Keywords:Transformer substation,110kV digital substation transformer,measurement and control protection,electrical two times design
