In this paper,a new integrative vulnerability evaluation model for the grid lines is presented based on both the structure vulnerability when the grid runs stably and the change rate of line capacity when the grid is attacked.The model integrates the evaluation methods of the structure and the physical process of power grid when the grid is attacked.And the model supplements the deficiency of the tradi-tional model and analyzes the fault of power grid more comprehensively.Therefore,the more accurate da-ta,providing an important basis for power grid vulnerability evaluation,operation and maintenance,can be obtained.Finally a simulation illustrates the correctness and effectiveness of the model.
