| 摘 要： | 2种全并联AT供电牵引网故障测距原理的实现难点是在进行故障测距时需要同步提取牵引网沿线的信息量.其中远端数据采集装置与故障测距装置的时钟同步是实现高精度定位的基础,分析表明基于精密时间协议的时钟同步方案较之已有方案有着更多的优越性,并给出具体接线方式.

| Abstract: | Two theories of fault location of all-paralleling at feeding system come true. The difficulty is how to synchronously get the current and voltage value of electric traction line. The synchronization from remote terminal unit used in collect value to fault location device is the essential of precise fault location. Compared with the other schemes of clock synchronization, the new IEEE Standard Precision Time Protocol (PTP) has further advantage. At last hookup is shown. |
