摘　　要：首次提出将物元分析理论用于电能质量的评估,并构建了电能质量综合评估的物元分析模型。针对电能质量综合评估的复杂性以及单因素识别和等级划分之间的不相容性特点,应用物元可拓集方法,构造物元矩阵,根据计算出的关联度大小对电能质量的等级进行可拓识别。实例计算结果表明:物元分析法用于电能质量综合评估,使评估结果更为客观、合理,有其独特的优越性。The synthetic quantified evaluation for power quality is one of the gist to weigh excellent or inferior of the power quality, and this is propitious to realize the electricity-purchase principle of discussing the price according to quality and high quality high price, thereby serve as to build the equitable electric power market. This paper proposes to use the method of matter-element for power quality evaluation, and then build the model based on the method of matter-element. Considering the non-compatible feature between the single recognition and evaluation results as well as the complexity of the evaluation for power quality, a model is approached for the evaluation of the power quality by using the matter-element and extension set. Case results show that use the proposed model is objective and reasonable, with a special advantage when used in power quality evaluation.
