摘要 为了提高电能质量模糊综合评价的客观性、科学性,提出了主观赋权法与客观赋权法相结合的组合赋权法来确定电能质量各技术性指标的权重,该方法克服了单一赋权法的不足。为了便于实际应用,减少计算量,提出了序列综合—G1法来确定权重,然后用该方法对公共连接点的电能质量进行模糊综合评价。计算结果表明组合赋权法得到的各指标权重更客观、全面,从而使评估结果更科学、准确。 To obtain a more objective and scientific result of power quality (PQ) fuzzy synthetic evaluation, this paper presents a combined weighing method to determine weights of PQ indices, The new method integrates advantages of both objective weighing and subjective weighing and remedies the defects of single-weighing. For more applications, a sequence synthesis-G1 technique is also put forward to evaluate PQ levels of the point of common coupling (PCC). Calculated results show that the proposed method with more objective and sufficient weights of PQ indices leads to a more scientific and accurate evaluation.
