The invention discloses a power system cascading failure mode prediction method, and relates to the technical field of power system cascading failure mechanism analysis. The power system cascading failure mode prediction method of the invention comprises the following steps: a, the steady-state power flow of a system before an initial failure is calculated; b, the comprehensive vulnerability index is calculated; c, the initial failure is determined; d, the comprehensive vulnerability index after failure is calculated; e, the comprehensive margin index Cij(s+1) of the system after failure is calculated; f, the (s+1)-level failure is determined; and g, whether the search termination condition is met is judged. According to the power system cascading failure mode prediction method of the invention, the possible cascading failure mode of the system is predicated by combining the power grid structure and state parameters, the predication indexes are combined with the actual situation of the power system, the calculation speed is high, a cascading failure set having a serious effect on the system is worked out and analyzed, and prevention of major blackout accidents caused by cascading failure can be enhanced.
