Abstract:

The fault current of the fault arc is affected by the load and is not easy to be identified.To solve this problem,the arc fault identification method based on principal component analysis and decision tree was proposed.The principal component analysis method was used to reduce the dimension ality of eight temporal characteristic parameters of current generated by the fault arc.After removing the redundant information,the three kinds of principal components were input into the decision tree as characteristic values to establish a classification model.The proposed method can effectively simplify the decision tree classification model,reduce the time of fault arc identification,and reach the accuracy of fault arc identification of 95%.

Key words: principal component analysis, time domain feature, decision tree, fault arc identification
