| Abstract: | Using the model which preserves network structure. this paper analyses operational variables during transient period, and presents a kind of analytic method to assess power system transient stability. Based on operational variables, the critical cutset and its stability index are defined. An algorithm is offered to calculate the transient stability power limit of the critical cutset. Examples illustrate the validity of the proposed method. |
