| 摘要: |
| 电压暂降（含电压短时间中断）等电力扰动都可能造成用户生产中断，给用户带来巨大的经济损失。开展电压暂降经济损失评估为合理投资电能质量治理措施提供坚实的依据，同时可以指导用户制定最佳生产计划。目前国内关于电压暂降经济损失构成及评估方法的研究还较少。针对不同类型的电压暂降，从工厂类用户因电压暂降引起生产中断的特征以及单次电压暂降事件引起的成本构成两个方面进行了详细的分析与讨论，并提出了单个工厂的电压暂降经济损失的评估模型。最后结合本课题组在国内调研的结果，给出了电压暂降经济损失的评估实例，计算结果表明通过分析和量化生产中断的发生次数、严重程度以及成本构成等。该模型可以较好地预估单个用户因电压暂降引起的经济损失。 |

| Abstract: |
| Voltage dips (VDs) (including voltage momentary interruption) could cause interruptions of the producing processes, which brings significant economic loss to end-users. The evaluation of the economic loss of voltage dips provides a solid foundation for reasonable investments on power quality mitigation measures, and could be used by the end-users to make production plans. Few relative researches have been done so far in China. In order to get an evaluation model of plant-level economic loss due to voltage dips, this paper presents a detailed discussion in two dimensions, including the characteristics of a producing process interruption and the composition of cost during voltage dips. At last, an evaluation example is presented to testify this model, according to the results of one power quality economic survey in China. The calculation result presents a precise prediction of the plant-level lost caused by voltage dips for one single user. |
