Multi-Criteria Adaptive Weight Fusion Method for Grounding Fault Line Selection in Distribution Networks

Based on zero-sequence current from the distribution network SCADA system, this paper constructs a multi-criteria adaptive weight fusion judgment mechanism (TEO energy, phase mean, phase variance, phase amplitude RMS) and realizes fault line selection via fusion scoring. MATLAB simulation verifies that the fault line selection method accuracy exceeds 99.3%, fully meeting the real-time fault line selection requirements of distribution network.
