| 摘 要： | 讨论了电力系统潮流雅可比矩阵最小模特征值与系统电压静态稳定性的关系,将最小模特征值定义为电压稳定裕度,在此基础上定义了电压稳定裕度对控制变量的灵敏度和PQ节点负荷灵敏度,用以找出对系统电压稳定性造成影响的因素和寻找系统电压薄弱点,同时给出了它们的算法。最后通过WSCC 9节点系统仿真计算验证其有效性。

| Abstract: | The relationship between minimal model characteristic value of electric power system tie flow Jacobin matrix and voltage steady-state stability is was discussed,and the minimal model eigenvalue is was defined as voltage stability abundant degree.On this foundation,the sensitivity of voltage stability abundant degree to control variables and to PQ point load are was defined in order to seek the factors of impacting voltage stability and explore the voltage weak point,and give out their algorithm simultaneously.Finally its validity through the WSCC 9 bus system simulation was confirmed. |
