Dispatching Automation Information Network Fault Analysis And Positioning Of The Research

With the development of substation automation technology,the network communication structure of substations has undergone tremendous changes.With the development of automation technology,the hidden dangers and fault points of network communication are increasing,and because the network communication structure is more and more complicated,these hidden dangers and trouble spots also become difficult to judge and locate.But the research and application of these problems has not achieved the desired effect,and because of these problems,often cause on-site operation and maintenance personnel,scheduling control personnel,automated maintenance personnel spent a lot of time and energy to analyze this problem.Therefore,in view of these situations,this paper will study a system that can quickly and accurately analyze and locate anomalies in the dispatching automation information network.Firstly,the paper introduces the structure of the automation information network and the most common network protocol.At the same time,then the original hardware design,software algorithm and data collection and storage in the substation automation information network are analyzed.Then,the data analysis,processing and system operation method of fault classification and location system of dispatching automation information network are discussed.Which mainly for the massive data collection,network analysis algorithm and hardware configuration were studied in order to achieve the best results.At last,the research and analysis of the actual operation and effect of the system in the substation are carried out.Compared with other existing systems,the system is a more advanced and reasonable information network fault analysis and localization system.The system is evaluated in three aspects: safety benefit,economic benefit and social benefit.From the point of view of system operation,the system can realize real-time storage and processing of massive data,protocol analysis,information classification,information correspondence,troubleshooting and other functions.Can be a rapid and accurate in electric power automation system of fault analysis and positioning of the function.Especially after the unattended operation of the EHV substation in Hebei South Network,the research and application of the system become field operation and maintenance personnel,automated maintenance personnel to locate network failure and other equipment to provide an important means of fault diagnosis.
