| description | The invention provides a distribution network terminal fault identification method, which comprises the following steps: firstly, acquiring original waveform data, performing normalization processing and hierarchical decomposition on the original waveform data to obtain event types of the original waveform data, extracting different types of original waveform data by using wavelet transform, and extracting the event types of the original waveform data; and obtaining original waveform data characteristics of the primitive level as a basis for fault waveform identification, calculating fault waveform data of an abnormal event based on a Bayesian joint probability function and an event type of the original waveform data, and carrying out fault identification. The distribution network terminal fault identification method provided by the invention has the advantages of less required data and strong anti-interference capability, effectively clarifies the line patrol target, improves the patrol efficiency and the po |
