Abstract
The embodiments of the present invention disclose a method and a related device for locating a ring power network fault. The method comprises: expanding in each ring line segment with an arbitrary point as a coordinate origin in a ring power network to construct a plurality of reference coordinate systems; acquiring monitoring point coordinate information and wavehead arrival time information of each of the monitoring point positions; acquiring assumed fault point information; acquiring a traveling wave propagation speed; constructing a plurality of distributed fault location equation sets according to the monitoring point coordinate information, the wavehead arrival time information, the assumed fault point information and the traveling wave propagation speed in each of the reference coordinate systems; and determining an actual fault position according to a solution result of each of the distributed fault location equation sets and the assumed fault section.
