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,能够直接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节点系统上进行了大量的仿真计算,对所提出的算法的精度和计算速度进行了校验。A direct method for frequency stability assessment of power systems is proposed in this paper, which is based on the latest Jacobbi Matrix of the power flow calculation. The method can directly calculate the final system frequency after the last switching without step_by_step integra1, and the system frequency stability can be determined. The proposed method has been used in the simulations of a 68_bus power system to test its speed and accuracy, and the results are satisfactory.
