The invention discloses a power supply equipment fault prediction method and device based on
deep learning, and relates to the technical field of power
system equipment fault prediction and
deep learning application. The method comprises the following steps: acquiring a
power grid topological structure, an equipment operation state, a historical fault
record, a real-time equipment load and environmental condition data; forming a space-
time correlation basic diagram according to the
power grid topology and the equipment operation state, and calculating the correlation strength by using a diagram neural network; calculating fault time
delay and determining a transmission path set by using a long short-
term memory network in combination with association strength and historical fault records; fusing multiple data to calculate a cross-regional
fault propagation probability, and generating a predicted fault path
list; and the fault prediction output of the long-short-
term memory network input is updated, and the real-time operation
data verification optimization of the
power grid is combined, so that accurate cross-regional
cascade fault prediction is realized, and safe and stable operation of the power grid is ensured.
