A kind of correlation analysis method based on zero sequence components was raised to carry out synthetic correlation analysis on zero sequence current waveform for each feedback line before and after fault. In coordination with bus bar insulation monitoring device and existing automatic reclosing device, fault lines were chosen out. Theory analysis and MATLAB experimental simulation show that the correctness and reliability of this kind of line selection has been improved obviously.
