西安交通大学本科生毕业设计(论文) 1 摘要 近几年来，随着城镇居民生活水平不断提高，榆林地区居民的人均用 电量也在稳步增长，最初变电站的容量已经不能满足本地区用电需求，为 此，再次设计一所变电站的作用变得非常重要。变电站在确保电网供电可 靠性方面具有十分重要的作用，110kV 变电站作为电力系统中的重要组成 部分已成为我国提高电力事业的关键领域。文章将结合110kV 变电站工 程在陕西省榆林市农村电网建设中的实际应用探究其一次电气部分设计的 详细情况，在110kV 变电站一次电气部分准备工作的基础上，探讨 110kV 变电站一次电气部分设计中配电装置、变压器、接线方式、电气设 备选型、短路电流计算等方面的内容。根据变电站设计的初始数据分析、 接线方式的设计比较以及设备选型的校验等方面的设计比较，最终确定了 该110kV 变电站的一次部分设计结果。本次对变电站的设计为后续的 110kV 变电站一次电气部分设计研究提供思考。 关键词： 变电站， 一次部分，设计，设备选型，电气主接线 Ⅱ Abstract In recent years, with the living standards of urban residents continue to increase, Yulin residents per capita consumption is steadily growing,the initial substation capacity has been unable to meet the regional demand for electricity, for which the re-design of a substation of the role of change Very important. Substation plays an important role in ensuring the reliability of grid power supply. 110kV substation is an important part of power system, which has become a key field of power industry in China. Based on the practical application of 110kV substation in rural power network construction of Yulin City, Shaanxi Province, this paper explores the details of the design of the primary part of 110kV substation. Based on the preliminary work of 110kV substation, the paper discusses the distribution of 110kV substation in the design of primary electrical part Devices, transformers, wiring, electrical equipment selection, short-circuit current calculation and other aspects. According to the initial data analysis of the substation design,the design comparison of the wiring mode and the calibration of the equipment selection, the design result of the primary part of the 110kV substation is finally determined. The design of the substation for the follow-up 110kV substation electrical part of a design to provide thought.
