Research on Four-Quadrant Input Over-current Fault Diagnosis of Electric Locomotive Based on Recursive 2-Classification Method

Four-quadrant over-current fault is one of the main faults of the HX<sub>D</sub>1 locomotive traction converter. Due to the class distribution of fault cause is unbalanced and there are a lot of over-current fault causes, four-quadromt over-current fault is difficult to distinguish and d...
