Design and Realization of Online Monitoring Data Processing System for Transmission Lines
To solve the problem of insufficient online monitoring data processing capacity of transmission lines,the design and realization of online monitoring data processing system for transmission lines are studied.The system hardware consists of four parts:distributed optical sensing monitoring module,data acquisition module,data processing module and result output module.In the software design part:firstly,the detection parameters are given;then,combined with the parameters,the data acquisition algorithm and data processing analysis algorithm are designed to obtain optimized data with higher credibility;finally,the monitoring data are analyzed from the three perspectives of ice overlaying,dancing,and lightning strikes to assess the real-time risk of transmission lines.Each module has a clear division of labor,and together they form a transmission line distributed optical sensing online monitoring data processing system.The test results show that:after using the system to process the transmission line monitoring data,the daily error is no more than 3℃,the error between the acceleration waveform and displacement waveform and the actual waveform is no more than 0.5 m/s2,and the tripping time can be accurately obtained;the lightning current at the point of fault obtained is 100%correct.The system can accurately monitor the ice-covered area,transmission line dancing situation and lightning strike situation,and it has strong monitoring ability for ice-covering,dancing and lightning strike,and has good working performance.
