为了提高空间行波传感器对故障行波信号检测的可靠性与检测精度,提出了一种寻找空间磁场行波传感器最佳安装位置的方法。该方法以传感器检测点磁场分布的数学模型为基础,通过极坐标系形式对输电线路故障后的磁场变化情况进行分析,发现当检测点的磁场变化在极坐标系中表现为圆形时检测误差最小,据此在不同输电线路排列方式情况下分析计算了最佳检测点位置。仿真结果表明,在文中方法求取的最佳检测点位置能有效检测故障行波信号,检测可靠性高,对故障定位精度有较大提升,有望进一步推动行波技术的实际应用。

In order to improve reliability and accuracy of fault traveling wave signal detection, this paper proposed a method searching the best location of space traveling wave magnetic field sensor. This method is based on the mathematical model of testing point's magnetic field distribution. Using polar coordinate system for transmission line fault analysis of magnetic field, it is found out that when testing point of magnetic field graphics is circular in polar coordinates, detection with minimum error is reached under different transmission line arr...
