Research and application of the fault information integration and intelligent analysis in distributed grid
In recent years,to build smart grid becomes a new focus,and how to fully collect and make effective use of the information of the intelligent secondary device get abroad attention. This paper presents a grid fault information intelligent analysis and processing system. It is a platform of fault information intelligent processing,used for an incorporate control center system of province and district level. It works in two parts,substation and control center. In the substation,a slave system device gather the information of relays and deliver it to the master system in the control center through Ethernet,and a recorder proxy device gather the information of recorders and deliver it to the master system through another Ethernet channel. The software in the control center has a layered and distributed structure,and import the information of relays and recorders with two isolated server in the data layer. The application layer of the software system can gather the information to a integrated report of a grid disturbance or fault with special process,include of using the fault index，fault time,etc. This method is effective of reduce the requirement of the hardware resource of the slave system,and can decrease the chance of Ethernet block. It can support the decision of the dispatcher and fleetly deal the gird fault. This system has been used in the control center of Taizhou district in Zhejiang province,and remarkably improves the level of management. The system is programmed to integrate with information of other systems,such as SCADA and EMS,and will get whole view of the grid information to give stronger support of building a smart grid.
