针对电力系统静态电压稳定性的弱节点排序问题，对灵敏度法和奇异参与因子法进行了比较。

The sensitivity method and the singular participation factor method in evaluating weak buses ranking of static voltage stability were compared with each other.

提出以节点电压非线性参与因子作为依据，衡量负荷节点对电压稳定性的影响程度。

The method makes use of the nonlinear participation factors and consequently the effect of power system nonlinearity on system voltage stability can be considered.
