To solve the problem of replacement priority assessment model of distribution transformers, we propose an assessment model for multi-level distribution transformer replacement priority, including the establishment of the evaluation system and presentation of corresponding calculation method. This model is based on fuzzy analytical hierarchy process and grey fuzzy comprehensive evaluation, and it covers different kinds of assessment factors. Firstly, a fuzzy analytical hierarchy process is adopted to establi...

0引言12013年,全国配电变压器电能损耗1.7×1011k Wh,约占全国发电量(5.32×1012 k Wh)的3.2%,相当于三峡电站2013年全年发电量(约1×1011k Wh)的1.7倍,电能损耗情况十分严重[1]。配电变压器损耗大的主要原因是我国电网结构落后,配电网中中小型老旧高耗能变压器拥有量过高[2],?
