| 摘 要： | 提出了衡量节点电压稳定的奇异值法,与衡量系统电压稳定的奇异值法相比,具有物理概念明确、计算量小的特点;通过对几种具有一定普遍性稳定指标的分析,总结了这一类指标的特点;讨论了最小奇异值表示的电压稳定裕度指标和物理量表示的电压稳定裕度指标间的关系;最后,就雅可比矩阵奇异、负荷功率极限和电压失稳临界值间的关系进行了探讨。

| Abstract: | A minimum singular value method for estimating node voltage stability is proposed. which has distinctive physical meaning and requires less computation work compared with the margin methods expressed by previous singular value. The features of stability index are concluded. The relation between the voltage margin index expressed by minimum singular value and the voltage margin expressed by physical quantity is dis-cussed. At last, the relation between the singularity of Jacobian martix. load power limit and load critical voltage is explored. |
