The On-line Monitoring Technology Of Transmission Line Galloping Based On RFID Sensor Tags

Transmission line galloping reaches a certain extent will cause serious damage,and often cause different levels of accident,such as inter-phase shortcutting,line tripping outage,pour tower,at the same time can cause damage to fitting and supporting structures.The transmission line galloping will seriously affect the quality of power supply and power supply reliability,endanger the safe operation of power grid,and even bring huge economic losses.A large number of researchers both at home and abroad have done a lot of research for the prevention and protection of transmission line galloping.Aiming at that various transmission line galloping monitoring methods have the defects of high power consumption,high cost and not suitable for long-term monitoring,this paper presents a galloping long-term monitoring design based on RFID acceleration sensor tags.In this paper,the research are great helpful for more in-depth understanding of the characteristics of transmission line galloping.First of all,this paper determines the wire vibration form of dance,and determines the transmission line galloping monitoring based on acceleration sensor is the basic way through the conductor mechanism and transmission line galloping and influencing factors of knowledge and research.Secondly,through the in-depth research of RFID technology,this paper designed the overall structure of the on-line transmission line galloping monitoring system based on RFID acceleration sensor tag,and on this basis to design a kind of RFID acceleration sensor tag structure.The system can realize transmission line galloping monitoring for a long time.Thirdly,this paper put forward the transmission line galloping mathematical basis by using acceleration sensor monitoring.By analyzing the exist in the process of acceleration acquisition of direct current component and high frequency noise error and the trend of the produced in the process of acceleration integral item,the ways of the average method and filter to remove direct current component and high frequency noise have been used.The using of wavelet analysis in signal decomposition and reconstruction to remove trend term is put forward.Given a simulated acceleration signal,using MATLAB software simulation,the simulation results show that the proposed algorithm is effective and feasible.Finally,the RFID acceleration sensor tag has been carried on the communicationperformance testing,and the tag has been used in the laboratory environment simulated transmission line galloping experiment.The experiment shows the feasibility of the proposed design scheme.
