摘　　要：文中研究了一种基于戴维南等值的电压稳定裕度快速求解算法,通过建立戴维南等效模型,求出其戴维南等值参数。根据电压崩溃点的临界条件,建立负荷裕度与等值参数之间的内在联系,从而计算出该节点的最大负荷裕度。IEEE14节点系统计算验证了该方法的准确性和可行性。A equivalent voltage stability margin fast algorithm based on Thevenin is presented in this paper.Through the establishment of the Thevenin equivalent model,Thevenin equivalent parameters can be calculated.According to the critical condition of the voltage collapse point,the internal relation between the load margin and the equivalent parameter is established,and the maximum load margin is calculated.The accuracy and feasibility of the proposed method are verified by the calculation of IEEE14 node system.
