摘　　要：探讨了基于《DL/T985-2022配电变压器能效技术经济评价导则》(Guide for determining energy efficiency for distribution transformers)的变压器经济选型问题,分析了在两部制电价条件下,变压器容量选择对综合能效费用的影响。通过建立计算模型,选取了变压器容量、空载损耗、负载损耗、变压器价格、贴现率、电价等参数,对变压器的经济选型进行了全面分析。研究结果表明,变压器容量是影响综合能效费用的主要因素,其影响权重远大于其他因素。提出了简化模型和设计建议,以优化变压器容量选型,提高负载率,减少容量电费。This paper discusses the economic selection of transformers based on Guide for determining energy efficiency for distribution transformers,then analyzes the influence of transformer capacity selection on comprehensive energy efficiency cost under the condition of two-part power price,and finally by establishing a calculation model,selects parameters such as transformer capacity,no-load loss,load loss,transformer price,discount rate and electricity prices to conduct a comprehensive analysis on the economic selection of transformers.The research results show that transformer capacity is the main factor affecting comprehensive energy efficiency costs,and that its influence weight is much greater than other factors.The paper also presents a simplified model and design suggestions to optimize the selection of transformer capacity,increase load rate and reduce capacity charge.
