摘　　要：输电线路的运行状态监测对整体电网的稳定运行具有重要意义。针对目前输电线路运行状态监测中容易出现数据丢包导致监测效果较差的问题,设计了一种基于小波变换的输电线路运行状态在线监测系统。将系统划分为数据采集模块、数据分析与处理模块以及数据在线交互模块等,利用多传感器采集输电线路运行状态数据后,利用小波变换的方式滤除运行状态数据中存在的噪声干扰。实验发现所设计系统具有较高的监测准确性和实时性,可有效实现输电线路运行状态的在线监测。Monitoring of the operation status of transmission lines is of great significance to the stable operation of the overall power grid.In view of the monitoring of transmission lines is designed.The system is divided into data acquisition module,data analysis and processing module,data online interaction module,etc.After collecting the transmission line operation state data with multiple sensors,the noise interference in the operation state data is filtered by wavelet transform.The experiment shows that the designed system has high monitoring accuracy and real-time performance,and can effectively realize the online monitoring of the transmission line operation state.
