地区电网规划设计
摘
要
本次设计的题目是“地区电网规划” , 内容分为:电力网络方案的确定、发电厂及变电站电气主接
线设计、厂及所用电设计、短路计算、主要设备的选择及校验、输电网络潮流分布的计算等部分。其
中输电网络的功率与电压分布及电器主接线的设计非常重要的,因为他们的可靠性、经济性和灵活性
直接影响着整个电网的可靠性、经济性和灵活性。还影响着厂用电设计、短路计算、设备的选择校验
等内容。本次设计的电力网络方案的确定及电气主接线经过经济性比较后最终所选出的方案中选取可
靠性比较高的为最后方案。另外,短路计算部分也是本次设计的重要部分。他的准确性影响着设备的
选择及校验,也影响到整个网络的经济性与安全性。本次设计是本着可靠性和安全性的原则来完成的。

Abstract
Thinking of this the design subject is “region power network design”The content is divided into
:Electric network methord’design, The electric desingn that the mainly wires of substation and power plant .
The mill designs in the way of the electricity 、 Short circuit calculation 、Selection of capital equipment
and check 、 the power and the voltage of the power system designed.
But the the power and the voltage of the power system designed and the main line designed are
very important.Because its retiability 、 Economy and mobility are directly affecting the entire power
network and plant dependability 、Economy and elasticity. Still affecting the main design in the way of the
electricity 、 Short circuit calculation 、The equipment selection check is up to standard to be contain .
This design eiectricat net programe after the economy comparatively afterwards finally follows in the of
choose selects taller one of dependability and the lower ecomomy to act as the last scheme.
Besides, the Short circuit calculation affecting the Selection of capital equipment and checkIt also
