摘　　要：为了解决输电线路在线监测数据处理能力不足的问题,对输电线路在线监测数据处理系统的设计与实现开展研究。该系统硬件由分布式光传感监测模块、数据采集模块、数据处理模块和结果输出模块四部分组成。在软件设计部分:首先给出了检测参数;然后结合参数,设计了数据采集算法和数据处理分析算法,获取了可信度更高的优化数据;最后从覆冰、舞动、雷击三个角度分析监测数据,以评估输电线路实时风险。各模块分工明确,共同组成输电线路分布式光传感在线监测数据处理系统。试验结果表明:使用该系统对输电线路监测数据进行处理后,日较差误差不超过3℃、加速度波形和位移波形与实际波形之间的误差不超过0.5 m/s^(2),可准确获取跳闸时间;获取的故障点雷电流为100%正确。该系统能够精准监测覆冰区域、输电线路舞动情况和雷击情况,对覆冰、舞动、雷击的监测能力均较强,具有较好的工作性能。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/s^(2),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.
