Software Design And Implementation Of Smart Substation Network Message Recorder And Analyzer

Compare with the traditional Substation,Smart Substation has realizing the networked in whole process level.No matter the actual operating data in the first side,or communication between secondary devices,is transforming by the Message forms.However,the Message is different from traditional measured values,it demands maintenance personal master the IEC61850 stipulations very well because of its complexity,it cause a great inconvenience in operation?maintenance,accident cause analyzing and overhaul of Smart Substation.This paper with the purpose of research of the functional requirements of Smart Substation for networked message,design a software which could complete the function like capture,record and analyze for the major message type(SV,GOOSE)in the process layer.The main research job and achievements as follows:Firstly,for the traditional substation,paper analyze its shortcoming and introduce the IEC61850 stipulations and its key technologies.Aiming at major message type in the process layer,introduce their structure,frame format and communication mode exhaustively.Then,paper proposed the overall structure of the software,and divide into some modules like Capture,Storage,Resolve and Searching according to different functions.And come up with the workflow design and implement method.And Aiming at the shortcoming of the current mass storage mode,adopted a newly recycle storage mode by the way of partition to the multiple hard disk,it could avoid the hard disk damage caused by frequent reading and writing effectively.Finally,by building the test environment,the functional modules are simulated and tested.The test results show that the design of the network message analysis software in this paper can achieve the corresponding functions.
