摘　　要：常规的智能配电网线路运行在线监测方法主要使用Comtrade三相采集单元提取线路暂态/工频分量,易受谐波磁化干扰作用影响,导致监测数据获取异常,因此提出了一种基于多传感融合的智能配电网线路运行在线监测方法。该方法基于多传感信息融合采集了配电网线路运行监测数据,利用重采样进行了监测数据降维预处理,生成了智能配电网线路运行状态在线监测评估流程,从而实现了智能配电网线路运行在线监测。实验结果表明,设计的智能配电网线路多传感信息融合在线监测方法在不同状态下均能正常获取监测数据,监测效果较好,可靠性高,有一定的应用价值。The conventional online monitoring of operating distribution lines mainly uses Comtrade three-phase acquisition unit to extract transient and power frequency components,whose results are easily affected by harmonic magnetization interference,resulting in abnormal monitoring data acquisition.In view of this a multi-sensor fusion-based online monitoring method is proposed.The method collects distribution line operation monitoring data by utilizing multiple sensors,pre-processes the monitoring data by resampling,and generates online monitoring and evaluation process for distribution line operation status,thus realizing online monitoring of operating intelligent distribution network lines.The proposed method has been verified by experiment capable of properly obtaining monitoring data under different conditions with satisfactory monitoring utility,and hence,highly reliable and worthy of application.
