摘　　要：根据输电线路故障时产生行波的特征能在极短时间内检出故障,研究了基于GPS(global position system)系统时钟同步方案,利用快速、高分辨率ADC、DSP,准确计算故障点至保护安装地点之间的距离,迅速而有选择性地切除故障线路的一种行波保护.According to that, that the feature of the traveling wave produced during fault transmission can be used to detect the fault rapidly, a synchronization scheme of system clock was investigated by using GPS （global position system）. The distance between the fault spot and the spot of protection device installed could be accurately evaluated with high-resolution ADC and DSP, being a traveling wave protection for fast cutting-off the fault line with selectivity.
