POWER GRID FAULT POSITIONING METHOD BASED ON BEIDOU SATELLITE

A power grid fault positioning method based on a Beidou satellite. The positioning method comprises: a monitoring module configured on a power grid line performing basic monitoring, and discovering a line section where an abnormal operation state occurs in the power grid line; then, assigning a first detection apparatus to perform fast detection on the line section where the abnormal state occurs, discovering a suspicious power grid assembly in which there may be a defect or damage, and uploading the positioning coordinates of the suspicious power grid assembly to a mobile base station; and then, assigning a second detection apparatus to further recheck the positioning coordinates of the suspicious power grid assembly, so as to determine the correctness of the positioning coordinates obtained by the first detection apparatus, and calculating the deviation between the second detection apparatus and the first detection apparatus after secondary positioning is performed, thereby ensuring the consistency and prec
