METHOD AND APPARATUS FOR FAULT IDENTIFICATION IN A POWER TRANSMISSION LINE |
摘要 |
<p>A method and apparatus for fault identification in a transmission line are provided. The method may include measuring at an end of the transmission line when the transmission line has a fault to obtain a measured signal g(t), comparing the measured signal g(t) with a predefined standard signal f(t), the predefined standard signal f(t) having beat frequency characteristic; and identifying that the fault is a transient fault if the measured signal g(t) matches the predefined standard signal f(t) according to a result of the comparison, or the fault is a permanent fault if the measured signal g(t) does not match the predefined standard signal f(t) according to the result of the comparison.</p> |
