【摘要】：针对目前配电变压器利用率缺乏评价方法的现状,提出了配电变压器年利用率的"四二三"评价方法。首先,对配电变压器年利用率各评价指标概念进行定义并对各指标的优秀范围进行估算;其次,根据年利用率母子指标的交互影响提出配电变压器年利用率的"四二三"评价方法,即综合年利用率母子指标的优劣限值组合将年利用率分为4大评价区域,23评价等级;最后,基于年利用率"四二三"评价方法提出配电变压器统筹调换策略。实例分析结果验证了评价方法的实用性及策略的优异性。
[Abstract]:In view of the lack of evaluation method of distribution transformer utilization ratio at present, the "423" evaluation method of distribution transformer annual utilization ratio is put forward. First of all. The concept of each evaluation index for the annual utilization ratio of distribution transformer is defined and the excellent range of each index is estimated. Secondly, the "423" evaluation method of the annual utilization ratio of distribution transformers is put forward according to the interaction between mother and son index of annual utilization ratio. That is to say, the combination of the combined annual utilization ratio of mother and son index divides the annual utilization rate into 4 evaluation regions and 23 evaluation grades. Finally, based on the "423" evaluation method of annual utilization ratio, an overall switching strategy for distribution transformers is put forward. The results of an example verify the practicability of the evaluation method and the superiority of the strategy.
