ABSTRACT: To aim at the distribution
parameter characteristics of UHV transmission line, this paper presents a fast
extraction method (FE) to extract the accurate fundamentals of current and
voltage from the UHV transmission line transient process, and locates the fault
by utilizing two-end unsynchronized algorithm. The simulation result shows that
this method has good performance of accuracy and stability, and has better
location precision by comparing with results of one cycle Fourier algorithm. Therefore
the method can efficiently improve the precision of fault location during the
transient process, and makes the error of location results less than 0.5%.
