Design And Implementation Of Transformer Online Monitoring System In Substation

Power has become an essential energy in the production and life of modern society.Power transformer is one of the most important power supply equipment in the power system.If the transformer fails,it is easy to cause power grid events or large-scale blackout accidents,affecting people’s daily work and life and social stability.In addition,the scale of power grid will be larger and larger in the future,and there will be more and more electrified equipment.At present,the monitoring methods of transformer are still relatively backward,which is difficult to meet the requirements of modern equipment management.In view of the above problems,in this thesis puts forward the solution of on-line monitoring of transformer,and strives to carry out real-time monitoring of the operation condition of transformer.In this thesis studies the related important stations,analyzes the actual needs of transformer online monitoring,and compares the situation of domestic and foreign equipment online monitoring.Based on the in-depth study and comparison of mature related technologies and commonly used equipment monitoring technologies,the convenience,safety,accuracy,economy and other aspects of the system are fully considered.A transformer online monitoring system based on.Net platform is designed.The system adopts client/server architecture(referred to as C/S architecture)as the software structure of transformer on-line monitoring system,in order to give full play to the advantages of C/S architecture in security,determines the three-tier structure mode of the system and designs the basic functional modules of the system.Using.Net framework platform for software development,on the one hand.Net platform supports C/S architecture development mode and excellent graphical human-computer interaction control mode,on the other hand,it provides visual studio ide integrated development environment,which provides great convenience for developers.Based on.Net platform,the system management,oil gas monitoring,iron core grounding current,oil surface temperature monitoring and other functional modules of transformer online monitoring system are realized by using C# language.Using the powerful data management ability of SQL Sever database,it provides data management,storage,query and other business support for the data of the system.In general,in this thesis develops a transformer online monitoring system based on C/S architecture +.Net platform + C# +sql sever,which realizes the original intention of real-time monitoring transformer operation situation.Through the index data of transformer operation,the fault representation can be found at the first time,and the scientific maintenance strategy can be formulated before the fault occurs,so as to ensure the long-term stable operation of the transformer and avoid the occurrence of large power failure.
