Design And Implementation Of Temperature Monitoring And Early Warning System Of High Voltage Switch

High voltage switch is an important infrastructure in power grid construction,which is usually deployed and managed by high-voltage switch GAbinet.With the continuous expansion of power grid s GAle of Panzhihua power supply company in recent years,the operation pressure of high-voltage switch is also increasing.At the same time,the company has higher requirements for the operation stability of high-voltage switch.However,due to the wide deployment of high-voltage switches,the disadvantages of temperature measurement mode directly through manual inspection are increasingly obvious.Therefore,the company organized and implemented a set of high-voltage switch temperature monitoring and early warning system to replace the original manual inspection mode.In this thesis,the design and implementation principle,method and technology of the system are analyzed and studied.In the research,the status and problems of high voltage switch operation and maintenance management in Panzhihua power supply company are introduced,the overall demand framework of the system is proposed,and the research and development requirements of the system are investigated from the perspectives of hardware,software and performance.Then,according to the requirement of high voltage switch temperature prediction proposed by the company,a set of GA-BP neural network algorithm is designed by using BP neural network and GA genetic algorithm to realize the accurate prediction of high voltage switch temperature.Based on the temperature prediction algorithm of the system,the system function is designed from the overall point of view,including the overall topology,software function model,etc.At the same time,the system is divided into three modules:real-time temperature monitoring,abnormal temperature warning and data query and statistics.The function sequence flow of each module is designed and analyzed,and the detailed techni GAl scheme of the system is obtained.Finally,through the C#technology and other software technology and tools,the realization ideas and methods of the system function module,core code are introduced,and the operation effect of the system is showed.Through the function and performance test of the system,it is concluded that the system achieves the expected research and development goals.Through the appli GAtion of the system,the remote and real-time monitoring of the high-voltage switch temperature GAn be realized based on the digital temperature monitoring sensor device in the high-voltage switch GAbinet and the power communi GAtion network,and the temperature trend GAn be accurately predicted and early-warning GAn be GArried out,so as to improve the automation level of business management.
