| Abstract: | 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. |
