摘要

配电网节能改造是新型电力系统建设的重要环节，配电变压器作为配电网的关键设备，其合理选型对降低配电网损耗具有重要意义。为解决现行选型方法对配变整体经济效益考虑不足，导致其损耗偏大的问题，文中提出了计及负荷分布特性与综合功率损耗的配电变压器选型方法。首先对比不同容量配电变压器的运行损耗曲线，提出考虑负荷分布特性的配变优选方法，分析其选型原理及优势；其次构建基于K-means聚类算法的负荷区间划分模型，选取中层负荷簇作为负荷聚集分布区；然后结合

年规划期内负荷增长，建立了考虑额定有功损耗和因无功消耗引起有功损耗的配变综合损耗成本模型。最后算例结果验证了所提方法在配变投资决策方面的有效性。

Abstract

The Energy-saving transformation of the distribution network is an important part of construction of new power system. The distribution transformer is the key equipment in distribution network and reasonable selection is of great significance for reducing the power loss of distribution network. For solving the problem that the overall economic benefit of distribution transformer is not considered enough in the current selection method and causing excessive loss，a selection method of distribution transformer considering load distribution characteristics and comprehensive power loss is proposed. First，the operating loss curves of distribution transformers with different capacities are compared

a optimization method of distribution transformer considering load distribution characteristics is proposed and its selection principles as well as advantages are analyzed. Then

the load interval partition model based on K-means clustering algorithm is constructed

and the middle load cluster is selected as the load aggregation distribution area. After that，combined with the load growth during the

-year plan

ning period，the comprehensive loss cost model of disribution transformer considering rated active power loss and active power loss caused by reactive power consumption is set up. Finally，the effectiveness of the proposed method in distribution transformer investment decision is verified by an example result.
