设计
中  文  摘  要
 
本次毕业设计的题目为“某110kV地方变电所的设计”,通过对变电站的设计,使我了解了变电所设计的基本流程及注意事项。在设计的过程中,我参考了《电力系统课程设计及毕业设计参考资料》、《电力工程专业毕业设计指南》等设计资料。在查阅资料的过程中,使我对电力系统的专业课程,特别是《发电厂电气部分》及《电力系统分析》这两门课程的内容有了更加深入的了解,加深了电力系统原理的认识。
本次毕业设计的基本任务是完成“某110kV地方变电所的设计”中的电气主接线的选择、短路电流计算、导体及电气设备选择、防雷保护规则以及高压配电装置及平面布置等方面的设计,在本毕业设计中根据基本任务的要求对各个方面逐一进行了闸述。通过对原始资料的分析及根据变电站的总负荷选择主变压器;并且根据电力供应和传输过程中的安全性、可靠性、灵活性、经济性等原则的分析比较,从而确定了最终主接线方案。

Abstract
This graduation Project of the subject is"110 kV electrical substation design", through substation design, I understand the basic design of the substation processes and attention to issues. In the design process, I Reference "power system curriculum design and graduate design reference materials", "Power engineering graduate design guidelines" and other design information. In the access to information process, on the power system of professional courses, in particular, "110 kV electrical substation design " and "electric system analyse". More in-depth understanding of these two courses, deepened the principle of power system understanding.
The graduation design the basic task is plete the "110 kV electrical substation part of the terminal design", in the main electric connection options, short-circuit current calculation, the conductor and electrical equipment selection, mine protection rules, as well as high-voltage power distribution equipment and layout, etc. Aspects of design, during the graduation project in accordance with the basic tasks of all aspects of the described one by one. By analyzing the raw data and according to the total load to choose the main substation transformer,and in accordance with supply and transmission of electricity in the process of safety, reliability, flexibility and economy of the principle of reciprocity, after parative analysis to determine The ultimate main wiring programme..
