Optimal Design And Implementation Of On-line Monitoring And Analysis System Of Transformer Oil Chromatogram

The Power Grid is an important part of the power system.Its core is transformer equipment,which can realize the conversion of different voltage levels and provide distribution support for the distribution network.Therefore,the operation status of the transformer directly determines the quality of power supply service of the whole power system.Power supply enterprises attach great importance to the abnormal monitoring of the transformer.According to the requirements of transformer management and based on the data of transformer characteristic gas concentration,an on-line monitoring and analysis system of transformer oil color spectrum is designed and implemented in this thesis.In the research process,firstly,the research status at home and abroad is analyzed,the technical basis of transformer anomaly analysis is analyzed,and the overall development goal of the system is proposed.Then,the functional requirements,communication requirements and non functional requirements of the system are analyzed in detail.The functional development objectives of the system are divided into six aspects: real-time data management,historical data management,equipment management,system log management,overrun data management and user management.On the basis of system requirement work,this paper analyzes the technical selection of the system,establishes the technical development plan based on.Net platform,and designs the topological structure,functional structure,functional process,class structure and database model of the system.According to the function design of the system,using the technology and tools of.NET platform such as C# technology and SQL Server database,this paper studies the function realization of the system,introduces the realization method and thought of the communication function of the system,as well as the realization thought,process,key code and effect of each function module.Finally,the test work of the system is studied,the test environment,method,process,content and result of the system are analyzed,and the research and development results of the system are evaluated.Based on the TROM-600 device,the system can collect the monitoring data of transformer characteristic gas concentration based on the power communication network.On this basis,the abnormal analysis of transformer operation state is realized,which reduces the workload of management personnel and improves the business efficiency of transformer operation and maintenance management.
