摘　　要：根据最近一次潮流计算的雅可比矩阵，提出了频率稳定分析的直接法，该方法不需进行逐步积分，能够一步计算出最近一次系统操作后的稳态频率，从而判断系统频率稳定性。本文在某６８ 节点系统上进行了仿真计算，对所提出的算法的精度和计算速度进行了校验，取得了满意的结果。A direct method for frequency stability analysis of power system is proposed in this paper,which is based on the Jacobi matrix of the last power flow calculation.The direct method can direct determine the final system frequency after the last switching without step by step integral,and is of the advantage of fast calculation.The proposed method has been tested by the simulations on a 68 bus power system and the results are satisfactory.
