| 摘 要： | 根据PQ可控性理论和电压／无功功率关系推出一种改进的雅可比矩 阵。在多机系统进行了论证和计算，结果表明此模型是可靠的。在简单系统讨论了 稳定裕度、最大功率与功率因数的关系。证明了新型雅可比矩阵奇异与全雅可 比矩阵奇异之间的关系。

| Abstract: | An improved Jacobian matrix is proposed in the paper based on the theory of the PQ node control-lability and the relation between voltage and reactive power. It is verified and calculated in multi-machinesystem ,the result shows that the modle is reliable. The relation of stability margin ,maximum power andpower factor is discussed at a single constant power load-infinte system. The singularity relation betweenthe improved Jaclbian matrix and the full one is proved. |

| Keywords: | voltage stability PQ controllability singular value decomposition (SVD) |
