The invention discloses an intelligent
relay protection hidden danger detection method and
system. The method comprises the steps of
data acquisition, data preprocessing, fault hidden danger prediction, fault classification and positioning and
relay protection hidden danger detection. The invention relates to the technical field of
relay protection hidden danger detection, in particular to an intelligent relay protection hidden danger detection method and
system.According to the scheme, a fine-grained relay protection hidden danger detection method for hidden danger detection to classified positioning is adopted, and the
fault occurrence probability and the trend change of the
occurrence probability are firstly detected and predicted; intelligent detection demand support is provided, and the type and the space-time position of the fault are determined by further executing classification positioning, so that the
overall efficiency, the intelligence and the detection dimension of relay protection hidden danger detection are improved; adopting a
time sequence convolution bidirectional gating circulation network combined with feature reconstruction optimization to carry out fault hidden danger prediction; and fault classification and positioning are carried out by adopting a convolutional bidirectional gating circulation fusion network combined with a position sensing graph.
