Abstract：The asymmetrical quadruple-circuit lines have different self-inductances, which cannot be decoupled by the twelve-sequence-component method. Phase-Line decouple method is adopted to eliminate the mutual inductance, and convert the original phase currents into 12 different independent current components. When a line fault occurs, the boundary conditions help to find out the relationship between the current components. If a fault occurs on different lines, the across components and loop components are in the same or inverse phase. The amplitudes of the components are the same while the phases are shifted a special angle during the same kind of fault on the different phase of same line. Considering the influence of the distributed factors, a fault phase selection method for asymmetrical quadruple-circuit lines is presented, flow chart for fault phase is also provided. The PSCAD/EMTDC simulation results show that this method is suitable for fault phase selection, and the fault location and fault resistance has little influence on this method.
