The invention discloses an auxiliary decision method for recovering the group multiattitude of a power system. With the method, the recovery scheme of black start, net rack recovery and a load recovery stage can be generated and a plurality of candidate recovery schemes are sorted; the generation process of the recovery scheme is divided into three steps so as to ensure that the method is self-adaptively changed into a scheme by taking the safety of the system as an optimizing object when the recovery scheme by taking the recovery time as the optimizing object is infeasible; different important degrees of a decider can be considered for the provided group polymerization function and the requirement on the independence between the number and the attribute of the scheme is not strict; the recovery object and the recovery scheme of the recovery object can be determined on line according to the recovery condition of the current power grid and the flexibility and the feasibility of the recovery auxiliary decision
