| Abstract: | On the basis of transmission line theory, double-frequency excited method to locate
line-to-line fault on power distribution network with tree structure is' presented. The fault
branch identificaiton, the fault location and the fault value are completed by means of the detection
signal transmitted from the start end to the terminals ,searching fault, sectionally, and
bi-frequency excited diagnosis. The tests of fault location on actual lines demonstrate that the
method is effective. |
