| Abstract: | A new double terminal method of travelling wave fault location is presented in this paper,which can effectively lower the influence of travelling wave speed and transmission line arc.The arriving intervals of the travelling wave from the fault location,reflected wave from fault location and reflected wave from opposite bus are recorded,then these intervals and location are used by the new method and the fault location is obtained by avoiding the wave speed and transmission line arc influences.The results of EMTP simulation show that this method is available and accurate. |
| Keywords: | travelling wave fault location wavelet transformation EMTP |
