摘要:随着经济的快速发展，电在我们生活中所扮演着越来越重要的角色，我们的生活中无处不在。而变电站的选址和布局又对变电站的建设和设计起到举足轻重的作用，选址直接影响未来电力系统的网络结构，供电质量和经济运行性。整体布局影响着变电站未来的日常电力运行，建设投产的经济可行性，还有未来发展中的电力运行的可靠性，安全性。
本设计在选址方面首先进行负荷计算，确定负荷中心，画出负荷区域，再结合影响变电站选址的原则和因素综合考虑，得出两个待选区域，并和理论负荷中心比较，以此得出最佳地址。
本设计在整体布局方面首先进行一次设备选型，来确定一次设备的基本型号和变电站主接线形式，再对变电站进行整体布局。并绘制主接线图和整体布局图。

ABSTRACT:With the rapid economic development, electricity in our daily life plays an increasingly important role in our life, everywhere. While the substation location and layout of construction and design of the substation play a decisive role, location directly affect the network structure of future power system, power quality and economic operation. The overall layout affect the daily electricity to run the future substation, the economic feasibility of construction and production, electric power operation of the development of the reliability and safety of the future.
This design in the area of the site first load calculation, determine the load center, draw the load area, combined with the effects of substation location principle and considering the factors, the two regions to be elected, and compared with theoretical load center, it is concluded that the best.
The first design a equipment selection in the overall layout, to determine the basic type and substation main wiring forms a device, in the overall layout of the substation. And the main wiring diagram and the overall layout drawing.
Keywords: substation location; layout;
