摘　　要：介绍几种静态电压稳定极限指标,如负荷裕度、雅可比矩阵奇异值、灵敏度指标、阻抗模等;对静态电压稳定极限及裕度的计算方法,包括奇异值分解法、灵敏度法、连续潮流法、直接法、非线性规划法等进行详细的总结和评述,指出它们各自优缺点;重点介绍计算一种N-1故障情况下电压稳定极限及其裕度的新方法,计算速度快,该方法具有很强的实用价值;最后介绍提高电压稳定的一些应对措施。通过全文可对目前静态电压稳定极限及裕度计算方法有一个全面了解和充分认识。Several indicators of static voltage stability limitations are introduced , such as load margin, Jacobi singular value, sensitivity indicators,impedance mode,etc. A variety of calculation methods calculating static voltage stability limitation and load margin are summarized, including singular value decomposition, sensitivity method, continuation power flow method, direct method, non-linear programming, etc, and their respective advantages and disadvantages are commented in detail. A new method of calculating voltage stability limitation and load margin is presented under N 1 topology, which has rapid calculating speed and well practical value. Finally some measures of improving voltage stability are introduced. The paper offers an introduction on calculation methods of the electrical power system＇s voltage stability limitation and loading.
