Fault location method, device and equipment and computer storage medium

The invention discloses a fault location method, device and equipment and a computer storage medium, and relates to the technical field of power systems. The fault location method comprises the following steps: acquiring target data of a measurement point after a power transmission line has a fault; the target data comprises voltage phasors and current phasors of a positive sequence, a negative sequence and a zero sequence of the measurement point after the fault occurs; constructing a target composite sequence network based on fault boundary conditions of fault points in the power transmission line; based on the target composite sequence network, constructing a target Kirchhoff voltage KVL equation set; and substituting the target data into the target KVL equation set, and solving to obtain the position of the fault point in the power transmission line. According to the embodiment of the invention, the influence of fault transition resistance on single-end distance measurement precision can be eliminated, th
