Abstract

The application discloses a kind of electric power line fault detection method and system, it is related to the technical field of intelligent detection, including the following steps, first judgment is carried out and first operation is executed, second operation is executed according to verification result, find influencing element, execute third operation, calculate the distance of the endpoint of the endpoint of fault point distance detection end.The present application quickly judges whether there is obvious abnormality in line through voltage fluctuation rate and other indicators, reduces the fault detection range, is convenient for detailed detection to each loop, quickly locates possible fault element through element verification, considers the mutual influence between element, avoids misjudgment or omission, ensures the effectiveness of subsequent operation, by calculating fault point distance, it is convenient for maintenance personnel to respond quickly, applicable to a variety of electric power line structure and fault type, with wide applicability, timely detection and positioning in the initial stage of fault, avoid fault expansion, guarantee the safe operation of power system.
