Study On Fault Information System Based On Real-time Monitoring And Analyzing

With the rapid development of AnHui power grid, the functions of the network system have been highly automated. But meanwhile, much information produced by kinds of microcomputer based protective relayings, fault recorders are short of effective management, the automatic level including monitor of rerlay protection and analysis of the faults is relatively droping behind. In this case, it is urgently to set up information management grid, provide resolvents for system faults and heighten the automatic level.Recently, there are many kinds of fault information processing systems researched by many corporations existing in the market, but most of them perform unsatisfactory. Aimed at getting resolvents, this paper, based on existed real-time supervisory and analyze system, builds up a fault information processing system according to AnHui power grid. It not only realizes protective information effectively used and data shared, but also combines the powerful real-time flat to automaticly perform analying, caculating, and managing tasks, which standardizes the performance and improves the dispatch level.The scheme is mainly composed of dispatch station and substation. Managing computer which installed at substation manage the information of microcomputer based protective relaying and fault recorder. After finished collection the messages of microcomputer based protective relaying and fault recorder, managing computer will classify, save, calculate and analyze them. And useful trip information will be sent to dispatch station through special line and be processed further at dispatch station.
