Abstract
A method for fault location to multi-terminal traveling wave in a direct current distribution line, which belongs to the field of power line fault ranging and location technology. The method includes a main site and a plurality of acquisition points installed into the distribution line and includes steps as follows. Step: collecting and uploading a traveling wave signal by each of the acquisition points after a fault occurs in the line; step: generating a fault record set; step: computing the shortest paths from a central site to other sites and their lengths; step: using expanded two-terminal traveling wave ranging principle for pairing computation; step: converting positions of possible disturbance points into possible disturbance occurrence time points; step: extrapolating from equal path lengths of the possible disturbance points to obtain disturbance time data; and step: determining a final disturbance point.
