| 摘 要： | 基于连续潮流分析方法,依据三种电压稳定指标(V-Q灵敏度、模态分析母线参与因子及负荷裕度灵敏度),在电力系统电压稳定崩溃点时的数量大小,识别对电压稳定有重要影响的负荷节点,找出这三种指标的等价性关系。利用上述方法对IEEE14节点算例系统和新英格兰10机39节点算例系统进行了分析,理论和算例都说明了在电压崩溃点处V-Q灵敏度、参与因子指标及负荷裕度灵敏度指标是互相吻合的。

| Abstract: | Based on the continuation power flow,the loads which have most influence on voltage stability can be identified according to the quantities of three kinds of voltage stability indices,namely V-Q sensitivity,modal participator and sensitivity of load margin,at the voltage collapse point of the power system.The equivalence among the three indices can thus be found out.The method was also applied to the IEEE 14-bus system and the New England 10-generator 39-bus system,and the results prove that the three kinds of voltage stability indices are consistent at the voltage collapse point. |

| Keywords: | voltage stability continuation power flow V-Q sensitivity participation factor load margin sensitivity |
