Abstract：  A feasibility study is carried out for utilizing the original power supply system to feed the expansion of a landmark project in Northeast China. The Phase Ⅲ load is estimated. The power consumption of Phase Ⅰ project introduced from the power supply bureau and the actual power consumption of Phase Ⅰ project are analyzed. The power supply distance of utilizing the original power supply system to feed Phase Ⅲ project is analyzed. Finally,conclusions are drawn in this paper:the power supply transformation adopts the method of increasing the load factor of the original power supply facilities；the original power supply system is utilized to feed the expansion project,so as to reduce the initial installation cost of the expansion part.

Key words：power supply transformation;load estimation;transformer installation capacity;load factor;initial installation cost;actual power consumption;high voltage incoming line;power supply distance

摘　要：对东北某地标性项目以原供电系统为扩建部分供电进行可行性研究：对3期负荷进行估算；分析从供电局引入1期的供电量及1期的实际用电量；研究采用原供电系统为3期供电的供电距离。最后得出结论：供电改造采用提高原供电设施负载率的方式，采用原供电系统为扩建部分供电，以降低扩建部分的初装成本。
