摘要
对电能质量进行综合评估得出的量化描述结果,可以作为用户选择供电服务的参考依据,有利于最终实现电能按质定价。作者将层次分析法(AHP)和模糊方法相结合,先通过 AHP 得到主观权值,再对得到的主观权值进行修正形成可变的综合权重;最后运用模糊综合评判对公共连接点(PCC)的电能质量进行评估,得到电能质量的等级和电能质量因子。实例计算结果表明该方法有利于区分电能质量等级及对电能质量进行定性和定量评价。
The quantified description from power quality synthetic evaluation is available for reference to the consumers in choosing the power suppliers, and it is also beneficial to fix the price according to the quality of electric energy. Combining the analytic hierarchy process (AHP) with fuzzy theory, at first the subjective weights are obtained, then by means of modifying the obtained subjective weights the changeable synthetic weights are formed, at last power quality at the point of common coupling(PCC) is evaluated by fuzzy synthetic evaluation and the power quality level and the power quality factor are obtained. Case results show that the proposed method is beneficial to distinguish power quality level and to conduct the quantitative and qualitative evaluation of power quality.
