Research For Intergrated Inspecting And Alerting System Of Digitalized Substation

As the technology of digitalized substation matures which is based on the IEC61850standard, it has fundamentlly changed the composition of traditional substation secondary equipments. We can depend on high intelligent equipment to combine the substation equipments with the secondary equipments. After that, it can tend to be more full digitalization and realize network information sharing, it also can make the data of the whole system tend to completion. For more simple and effective production management and improving the benifits of electronic transformation, we can use above information to complete the real-time supervised and unattended security system.We mainly use distributed intelligent technology to analysis the unattended security system of the digitalized substation. When we find hidden troubles or the system is not normal, it can greatly decrease the possibility of accident happening. If an accident has happened, we could narrow affected range with the fastest speed to response and make trouble-free area normally operate. It realizes real-time supervision and ensure the security of the equipment, so as to be a real-time supervised security system.Firstly, the thesis introduces intergrated inspecting and alerting system of the digitalized substation, the digital platform which is shared by the functions of the digitalized substation.Subsequently,the thesis introduces the the digitalized substation panoramic data acquisition platform, researches and realizes the method of acquisition, develops substation communication server object. It makes data resouses form the only and consistent basic information which is based on the same section. Through the unified standard and modeling, it also realizes information interaction and sharing between internal and external substation.Next, we use GOOSE(face to the commone object oriented substation events) model to make the digital remote viewing system react to control change, switch operation, failure occurrence of equipments and so on. Through the automatic identification and optimized processing, we can rapidly take the corresponding control and then build an integrated controlled intelligent remote viewing system.Finally, through setting mendatory network cards and using network sniffer techniques, we realize GOOSE and network communication message linkage wave record, sample values waveform reduction and othe message anlysis. It realizes the real-time supervision and assessment of the digitalized substation network performance...
