外文摘要：The studies of the phenomena of transient travelling waves on transmission lines have been stagnated in the theoretically phase and EMTP simulations. In fact the actual phenomena of transient waveforms of travelling waves is much more complicated than what we get from simulation which engenders the difficulties of using every single-ended travelling wave based on location algorithms that has been advised so far. In order to better apply the Type A single-ended modern travelling wave based on fault location principle for transmission lines which achieved by using fault induced transient travelling waves to the actual waveform based on transient analysis it is classified to 3 independent modes of operation including: standard mode, extended mode and consolidated mode respectively. Each with the typical demonstrations of being used on the analysis of actual current transient waveform. The actual fault analyses proves that Type A principle does have high veracity with the absolute location error less than 500 m.
