电能质量的经济损失评估与选择性治理

Economic Loss Assessment and Selective Governance of Power Quality

阐述了电能质量经济损失评估的重要性和必要性,强调了电能质量分类的重要思想。根据连续型电能质量问题的特性,将各指标分为质量合格和不合格两个区间,并提出了基于质量损失函数的评估方法计算各指标超标所造成的经济损失。此外,本文充分地考虑了事件型电能质量问题的影响范围和程度,并根据其特点确定直接和潜在的经济损失评估模型。最后提出了根据电能质量经济损失评估进行选择性治理的思想,解决了技术效率和经济效率之间的平衡问题。

The importance and necessity of economic loss assessment of power quality problems is discussed in the paper and the idea of meaningful classification of power quality problems is emphasized.According to the characteristics of continuous power quality problems,all problems are divided into two intervals,namely acceptable and unacceptable,and assessment methods based on quality loss function are proposed to calculate the economic loss caused by the continuous power quality problems in unacceptabe interval.In addition,effects of event-based power quality problems are fully considered,and their direct and potential economic loss assessment models are determined according to their influence.At last,the idea of selective governance of power quality based on ecomomic loss assessment is proposed,which solves the balance problem between technical and economic efficiency.
