摘要
本文基于矩阵的特征谱分解，阐述了一种电压静态稳定性的分析方法．该方法能够定量地给出系统电压的静态稳定裕度，并能够直接给出稳定裕度对系统状态变量和控制变量的灵敏度．文中还详细地给出了稳定裕度的计算过程且在算法上应用了雅可比矩阵的稀疏特性，有效地节约了计算机时和内存．
A method for analyzing the steady state voltage stability of elctric power systems based on eigen spectrum decomposition of the jacobian matrix is presented. This method can not only be used to calculate the steady-state voltage stability margine, but also be empolyed to compute the sensitivity of stability to system state variables and control variables directly. The detailed calculation procedure of stability margine is proposed and the sparse characteristics of Jacobian matrix are utilized to reduce the computation time and memory space requirements.
