摘　　要：电能质量对现代制造业和工业控制过程的重要性日益增加,持续几个周期的供电电压暂降和中断都可能给敏感用户带来巨大的经济损失。文章采用实地调研方法,针对上海地区5个典型工业行业中23个电能质量敏感用户,对电压暂降和供电中断造成的经济损失进行了评估,得出了电压暂降和供电中断对不同行业的年经济损失水平。Power quality is becoming more and more important for modem manufacture and process control industries, any voltage sags and momentary interruptions on the power supply voltage lasting more than a few cycles will bring massive economic loss. An evaluation of voltage sags and interruptions cost is given for twenty three sensitive customers in five industry categories by customer damage survey method, and the results indicate the annual level of economic loss in different industries due to voltage sags and interruptions.

关 键 词：电压暂降 供电中断 经济损失 评估 调查
