Abstract
The present invention is an unsupervised integrated method of instability detection and fault module positioning, including: acquiring a topological structure of a direct current (DC) microgrid and collecting electrical data of each node in the topological structure to construct a corresponding first enhancement dataset and a corresponding second enhancement dataset; constructing a fault type pool based on the topological structure; constructing a corresponding classification network based on a twinborn network framework; training the classification network using the prepared datasets to obtain a detection model; and inputting the electrical data of the DC microgrid to be detected to a detection model, to output whether the DC microgrid to be detected has system stability and a corresponding fault type. Further provided in the present invention is an unsupervised integrated device of instability detection and fault module positioning.
