A Fault Line Selection Method for Distribution System Based on Distribution Automation Data

摘要：

　　Most distribution networks in China are neutral indirect grounding systems,when single-line-to-ground(SLG)fault occurs,the fault current collected from outlet is very small and result in a low accuracy when selecting fault lines.Existing feature-based fault line selection methods select fault lines by extracting fault features from the fault current of outlets.The accuracy of these methods is greatly affected by the precision of ZCTs,because for each outlet,only one set of data is collected.With the popularity of distribution automation,a large number of distribution terminals are installed in the distribution network.To break through the limitation of ZCT precision,this paper presented a fault line selection method based on distribution automation.This method applies huge distribution automation data to select fault lines,and overcome the defeats of existing methods.A simulation is conducted to demonstrate the feasibility of this method.
