摘　　要：针对电压骤降对新型电力负荷的影响日趋严重,造成的因工业生产中断而引起可观的经济损失的问题,文章介绍了电压骤降的基本概念、成因及影响因素;详细阐述了电压骤降的监测与随机预测,并提出几种减少电压骤降的技术措施;最后探讨了电压骤降今后的研究方向。With the rapid development of modern high-technology industries, a large amount of new type power load that is sensitive to voltage level are put into use. Voltage sags have done more harmful effects on the new power loads than ever, and also brought great economy losses for industrial production. This paper introduces the definition, affected factors of voltage sags, and surveys its monitoring, stochastic prediction. Several mitigation methods are discussed in detail and the research in the future is also directed.
