摘　　要：随着配电网的发展,大量高耗能配电变压器面临淘汰更换,因此配变型式和容量的优选方法研究十分重要。基于配变负荷数据采集的完善程度不同,提出了一种考虑数据采集差异化的配变优选方法,分别建立了不同采集方式下的运行损耗成本模型;在对配变全寿命周期成本(life cycle cost,LCC)分解的基础上,以LCC最低作为配变优选原则,兼顾了配变初始投资成本与后期运行维护成本;最后,基于江西省某市10 k V馈线的配变选型实例,借助Matlab软件分析了LCC在不同配变类型下随容量的变化趋势。结果表明,所提模型及优选方法具有较强的可操作性,对配电变压器的科学选型具有指导意义。A large number of high energy-consumption distribution transformers are faced with elimination and replacement due to distribution system development. Therefore, research on selection method of distribution transformer becomes important. Based on load data acquisition level, an optimization method of distribution transformer considering data acquisition difference was proposed and different loss cost models were built respectively. On basis of decomposition of distribution transformer life cycle cost（LCC）, this article established an optimization principle of the lowest LCC, taking into account initial cost and later operation maintenance cost. Finally, taking distribution transformers in a 10 k V feeder in Jiangxi province as example, LCC change tendency for different distribution capacity is calculated with MATLAB. Results show that the model and optimization method has high operability. This optimization method has practical guiding significance in distribution transformer selection.
