| 摘要: |
| 首先介绍电压凹陷的一般概念。从幅值和持续时间所反映的波形特征上对各种电压凹陷进行分类。基于系统可靠性的分析方法提出电压凹陷影响评估的方式并给出性能指标，考虑了敏感负荷的要求和电压凹陷的量化标准。最后简要介绍了电压凹陷的一般控制方法。 |

| Abstract: |
| The general aspects of voltage sags are discussed. New characterization methods consi-dering the magnitude and duration of voltage sags are used for classification. An assessment approach is presented in terms of reliability analysis methods. The performance indices relative to the requi-rements of sensitive loads and the quantities of voltage sags are given to assess effect of voltage sags. Several products for mitigating the effect of voltage sag are briefly described. |
