Abstract: Provided is a precise fault location method for a collector line in an onshore wind farm. The method includes sends sending, by a slave unit, a high-voltage pulse signal at the beginning of a collector line to measure a cable length at a fault point of the collector line. A master unit and the slave unit send high-voltage pulse signals to each other to measure a cable length at any point on the collector line, thereby obtaining a geographical location corresponding to the cable length. The two measured cable lengths are compared and if the measured lengths are inconsistent, the master unit is moved, to make the two measured lengths equal with multiple approaches. In this case, the position of the master unit is a geographical location corresponding to the fault point.
