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 assessing the economic loss of power quality are expounded, and the important idea of power quality classification is emphasized. According to the characteristics of continuous power quality problems, each index is divided into two sections: quality qualified and unqualified, and the economic loss caused by the exceeding of each index is proposed based on the assessment method of quality loss function. In addition, the paper fully considers the scope and extent of the incident power quality problems and determines the direct and potential economic loss assessment models according to their characteristics. Finally, the idea of selective management based on economic loss assessment of power quality is put forward, which solves the balance between technical efficiency and economic efficiency.
