Intelligent power capacitor partial discharge detection method and system

The invention relates to the technical field of data processing, and provides an intelligent power capacitor partial discharge detection method and system, and the method comprises the steps: collecting a plurality of current data of a power capacitor; performing hierarchical clustering on the current data to obtain a hierarchical clustering tree; acquiring a first father node of each piece of current data according to father nodes to which each piece of current data belongs in different layers of the hierarchical clustering tree; according to the change of other current data in the father nodes of the current data, the merging threshold value of the first father nodes of the current data and the distribution of the first father nodes of other current data in the first father nodes, obtaining the abnormal probability of each current data; and performing partial discharge detection on the current data of the power capacitor according to the abnormal probability. The invention aims to solve the problem that a d
