Fault Location Method Based on SVM and Similarity Model Matching

Figure 2

Two faults on different branches. M₁: the bus of monitoring point 1. M₂: the bus of monitoring point 2. F: failure point. Fault 1: the first failure. Fault 2: the second failure. : the positive sequence impedance between M₁ and fault point F. : the positive sequence impedance between M₂ and fault point F. : the short-circuit positive sequence current at F when fault 1 occurs at F. : the short-circuit positive sequence current at F when fault 2 occurs at F.
