Abstract:

利用配网电缆线路便于安装同步信号采集装置的特点,提出了采用点散式测量的行波故障定位方法。基于HHT运算,定义了暂态含量系数,对各测点提取波形的残留暂态含量进行表征,按照残留暂态含量大小对测点排序。结合三端测距公式,循环替换测距三端,最终确定故障分支、区段。而后考虑D型测距原理的精度特点,选择靠近故障点且尽量对称的精确测距双端,削弱电缆严重的色散效应及多分支结构造成的波形畸变影响,重新进行精确测距。同时选取测速点实测波速,避免采用经验波速带来的误差。点散式测量可提供大量冗余数据,为测距提供了很大灵活性,极大提高了测距的成功率。经大量仿真验证,此方法精度接近离线方法,符合实际要求。
