Description

technical field

[0001] The invention relates to the field of electric power technology, in particular to a classification method for distribution network fault types. Background technique

[0002] The distribution network is an important part of the power system. With the rapid development of the smart grid, a large number of uncertain connections of distributed power sources make the fault information of the distribution network more and more complicated, and the accurate and rapid analysis of the fault becomes more and more difficult. In order to ensure the highly intelligent operation of the distribution network, real-time monitoring of feeder operation data, timely warning of abnormal conditions, and rapid fault detection and processing are required. Among them, the identification of distribution network fault types is an important function of intelligent distribution network. The traditional distribution network fault type identification either uses the expert library t...
