| 摘 要： | 探讨了一种多指标综合电压稳定性辨识方法。该方法基于节点电压变化、电压有功灵敏度、母线参与因子三个电压指标，以客观赋值与主观赋值组合方法对上述3个指标分别赋予不同权重求得综合指标以辨识系统各节点薄弱程度。最后以湘西南某实际电网为仿真对象进行分析，以单一指标与综合指标分别辨识系统薄弱母线，验证该综合辨识方法的全面性、有效性与科学性。

| Abstract: | This paper discusses a kind of static voltage multi-index comprehensive evaluation method. The method is based on node voltage changes, voltage active/reactive power margin three voltage sensitivity index, fully considers the different factors influencing voltage stability, and combines with the subjective assignment to the objective value assignment method of each index respectively and gives different weights to calculate comprehensive index. Finally, a real power grid of Hunan southwest is simulated and analyzed, of which single index and integrated index are used respectively to identify system weak buses, verifying the proposed identification method is comprehensive, effective and scientific.
