    摘要:

    在不影响行波检测精度的前提下,提出一种基于电场探针的行波检测方法以降低检测成本。该方法根据输电线路周围的空间电场情况,利用镜像法理论对输电线路附近的电场分布进行分析,选择恰当的检测位置安装探针以检测空间电位。探针不与输电线路直接接触,可在不停止运行的情况下进行安装与检修,通过接地线得到该电位产生的感应电流,再利用固有时间尺度分解方法分析感应电流信号以提取故障行波信号。仿真结果表明,利用探针感应电流表征输电线路上的电压信号的方法是可行的。此外,该方法定位误差较小,精度高,能够实现跨度较长输电线路的故障检测。

    Abstract:

    In order to reduce the cost of traveling wave detection without affecting the accuracy, a traveling wave detection method based on electric field probe is proposed. According to the conditions of the space electric field around the transmission line, the electric field distribution near the transmission line is analyzed by using the mirror theory. Then the appropriate detection position is selected to install the probe to detect the space potential. The probe is not in direct contact with the transmission line, and can be installed and repaired without stopping the operation. The induced current generated by the potential is obtained through the ground wire. Using the inherent time scale decomposition method, we analyze the induced current signal to extract the fault traveling wave signal. The simulation results show that the method of using the probe induced current to characterize the voltage signal on the transmission line is feasible. Moreover, the method has small positioning error and high precision, and can achieve fault detection for longdistance transmission lines.
