The invention belongs to the technical field of power fault diagnosis, and particularly relates to a line fault diagnosis method based on satellites and
meteorology, which comprises the following steps: regularly acquiring
satellite images and storing the
satellite images into an
image database, identifying
risk source information and storing the
risk source information into a hidden danger
database; starting a pre-disaster
satellite emergency patrol process of the
disaster area, bringing an acquisition result into an
image database, identifying
risk source information, calling data in a hidden danger
database for comparison, and outputting a risk source
list of the
disaster area; the method comprises the following steps: starting an emergency patrol process after a fault of a fault area, bringing an acquisition result into an
image database, identifying risk source information, calling data in a hidden danger
library for comparison, outputting risk source change information before and after the fault according to a comparison result, and determining the
risk area according to the risk source change information, meteorological data during the fault and fault characteristics of a fault site. And fault source screening is carried out. According to the invention, by using real-
time data provided by satellites and
meteorology and combining an intelligent analysis technology, rapid line channel
foreign matter source searching before a disaster and accurate
source tracing after a fault are realized.
