Abstract

The embodiment of the invention provides a multi-branch power transmission line fault positioning method, device, equipment and system. The method comprises the steps: obtaining the operation state information of a power transmission line, wherein the operation state information comprises abrupt change current and abrupt change time; when the abrupt change current exceeds a first threshold value and the abrupt change time exceeds a second threshold value, obtaining a fault type of the power transmission line; performing fault positioning and dotting in a line topological graph according to the geographic information system to generate fault nodes; and acquiring position information of a fault node, and sending the position information and the fault information to a user terminal. According to the invention, the fault location dotting is carried out in the line topological graph by using the geographic information system, and the overall comprehensive research and judgment is carried out on the fault position of a multi-branch power transmission line, so that the problems of inaccurate line fault location and false alarm are solved, and the situations of false alarm and confusion caused by on-site fault judgment are avoided.

Description

Technical field [0001] The invention relates to the technical field of overhead line fault processing, and in particular to a method for locating faults on multi-branch power transmission lines. Background technique [0002] The power industry is a pillar industry of the national economy, and transmission lines are the core of the power system. The safe and reliable operation of the power system is the key to the rapid development of the national economy. In recent years, due to the long transmission distance of the transmission line, the many branches of the line, the complicated operating conditions, the harsh environmental and climatic conditions, and the occurrence of power system paralysis caused by the failure of the transmission line, timely fault location and troubleshooting are essential. . [0003] The existing technical solution is to use on-site overhead remote transmission terminal equipment to make instantaneous, permanent and ground fault judgments based on the data...
