摘要
采用物元-可拓学基元分析及关联函数,结合熵权法,建立了电能质量的客观评价模型。采用关联函数对单项指标进行度量,克服了集合方法不能准确度量指标,以及模糊隶属函数无法度量超出单项指标范围的缺陷;采用熵权法计算指标权重,克服了主观确定权重评价方法缺陷。最后通过实际算例验证了该方法的可行性。
An objective evaluation model of power quality has been established by the base element analysis of matter element-extension,relation functions and entropy method. Relation functions were used to measure single index to overcome the inaccuracy of set method, and the defect that the fuzzy membership function can not measure beyond the index range. The entropy method was adopted to calculate the index weight to eliminate the shortcoming of evaluation method based on subjective-determining weights. The feasibility of the method was verified by the practical example.
