摘要： 随着城市化进程的加快，配电网网架结构的不合理、供电能力不足等问题日益突出。不断优化城市配电网络结构，对配电网供电能力和设备利用率具有重要的影响。文章在充分调研快速发展地区配电网的基础上，主要研究变电站供电能力与主变容量、主变负载率、负荷密度、供电半径之间的密切关系，在讨论了充分发挥变电站效能的同时，联系了变电站互联设计，从而由点到面地对优化配网结构做了理论分析和案例计算。

Abstract: With the accelaration of urbanization, the problems of the unreasonable distribution of space truss structure and the shortage of power supply capacity problem become increasingly eminent. Constantly optimizing the structure of urban distribution network has an important influence on the distribution network power supply capacity and utilization rate of equipment. This paper, on the basis of investigating the rapid development of regional distribution network, mainly researches the relation between substation power supply ability and the capacity of main transformer, main transformer load rate, load density, and the power supply radius, and discusses maximizing the potential of the effectiveness of substation while relates with substations connected design. Then the paper provides the theoretical analysis and case calculation on improve the structure of distribution networksurface.
