Fast Identification Method and Application of Line Lightning Strike Fault Based on Fisher Score
Aiming at the problem of frequent increase of line lightning faults threatening the stable supply of electric power,a feature mining and fast identification method of lightning strike fault based on Fisher score is proposed.Firstly,the mechanism of line lightning strike faults is deeply analyzed,and the characteristics of the electrical quantity at the moment of lightning faults is discovered and summarized.Then,the feature mining method based on Fisher score is used to calculate the importance degree of each feature of the lightning strike faults.And then,based on the information of the fault recording system and the lightning locating system,the fast identification of the line lightning strike faults is realized by establishing the typical feature information database and the intelligent analysis module.Finally,it is proved that this method can realize the fast identification of line lightning strike faults through simulation verification and example analysis,and this method significantly improves the reliability of the power system and the maintenace efficiency.
