Protective measures can be rapidly and reliably taken by timely and correctly selecting the fault phase coping with the line protection, as well as the right operation of single-phase tripping and single phase re-closing. Traditional selection method is insensitive and insufficient in dealing with fault resistance, fault position, mutual inductance between closed lines, reactive effect and the in-sufficient for system parameters using power frequency component. This paper has proposed series multi-resolution morphological gradient (SMMG) filter, to extract the deviation of power frequency component of mode current, constructing a new phase selecting component of fault phase component, which provides a solution to fault phase selecting component of fault phase component.
