电气工程及其自动化专业的毕业设计是培养学生综合运用大学四年所学理论知识，独立分析和解决工程实际问题的初步能力的一个重要环节。
本设计是根据“电力系统及自动化专业（发电厂及电力系统）”毕业任务书的要求，综合大学四年所学的专业知识及《电力工程电气设计手册》，《电力工程电气设备手册》等书籍的有关内容，在指导教师的帮助下，通过本人的精心设计论证完成的。整个设计过程中，全面细致的考虑工程设计的经济性，系统运行的可靠性，灵活性等诸多因素，最终完成本设计方案。
本设计说明书是根据毕业设计的要求，针对220/60kv降压变电所毕业设计论文。本次设计主要是一次变电所电气部分的设计，并做出阐述和说明。论文包括选择变电所的主变压器的容量、台数和形式，选择待设计变电所所含有的各种电气设备及其各项参数，并且通过计算，详细的校验了各种不同设备的热稳定和动稳定，并对其选择进行了详尽的说明。同时经过变压器的选择和变电所所带负荷情况，最后确定本变电所电气主接线方案和高压配电装置及其布置方式。论文包括设计的说明和设备选择的计算，并附有设计图纸（电气主接线图一张、变电所断面图两张、平面布置图一张、防雷保护图一张、继电保护原理图一张），可为以后的设计做些参考。
This design according to“electric power system and automation professiom( power plant and electric power system )”the request that graduate the mission book, symthesize the four years in university a profession for learning knowledge and《electric power engineering electricity design manual》, etc. Umder the help that guide the teacher, pass oneself of design what argument complete with meticulous care. Whole design process inside, completely economic that meticulous comsideration engineering design,dependable that system circulate, vivid etc.many factors, end complete this design project.
This design the main according to the request that graduate thed design, aiming at the 220/60kv decline to press to change to give or get an electric shocd a graduate the design the thesis. The design is based on summarizing our coumtry's substation design and operation. It takes the selections of devices which this substation needed such as the type of electric bus, the type of the power distribution. It is made up of the instruction and the caculating parts. And for blueprints(siuation main connected wires picture, the plot and section of the substation, transformer protective principle connection picture), It can be unsuited for the same design in future.
由于时间紧张和能力有限，此论文中难免会出现遗漏和错误，希望老师给予指点和更பைடு நூலகம்。
最后，感谢各位老师给予我的帮助和大力支持，正因为你们精心的指导本次论文才得以更好的完成，再次表示深深的感谢！

Abstract
Electrical engineering and professional graduate in its automation designs is an important link of the first step to trains student synthesize to make use of the four years in umiversity an academic theories theory knowledge, independence analysis definitely reach agreement engineering actual problem ability.
For my limited knowledge, it is impossible to be no mistakes in the draft. I hope the teacher give to point out with make correction.
Finally, thanks for each teacher to cive my help with support strongly, positive because you with meticulous care of leading this thesis just can better complete, mean the profound with gratitude again!
