The application discloses a low-
voltage network anomaly diagnosis method based on multi-source heterogeneous data fusion, relates to the technical field of low-
voltage network anomaly diagnosis and operation and maintenance, and comprises the following steps: collecting multi-
source data, pre-
processing the data by
edge computing, adjusting the collection interval according to changes,
processing the data by
deep learning and other technologies, converting according to
semantics, improving formula
standardization, fusing the data by
federated learning, dynamically weighting and intelligently interpolating, constructing a rule base, optimizing by
reinforcement learning, setting a dynamic threshold, training a model based on Transform and GNN, improving the effect by contrast learning,
monitoring data in real time, warning in multiple ways when an anomaly occurs, assisting in
troubleshooting by AR, and repairing the anomaly by a
robot. The application can fuse multi-source heterogeneous data and improve
data quality, the diagnosis model and the rule base are accurate and efficient, anomalies can be found in time, the operation and maintenance cost is reduced through intelligent early warning, AR-assisted
troubleshooting and
robot repair, the stable operation of the low-
voltage network is ensured, and the economic and
social benefits are remarkable.
