摘要
通过分析简单交流支路的功率负荷能力,提出了求取静态电压稳定临界点的新算法。在确定临界电压崩溃点的基础上,通过比较不同的计算裕度指标的方式,提出采用复功率差值的模来表示静态电压稳定裕度是比较合理的。本文还给出了IEEE 5节点系统的算例。
The new calculating method of stationary voltage stability critical node is put forward by analyzing the ability of the load power of simple alternative circuit branch. Based on the collapsing node of the critical voltage, the suggestion that the stable margin of stationary voltage is proved reasonable by comparing with the different indications of calculated margin. Case of IEEE 5 node algorithm system is proposed as well.
