1、毕业设计(论文)材料之二(2)本科毕业设计(论文)开题报告题目:采用半屋内GIS配电装置的矿区110kV降压变 电所设计课 题 类 型:设计 实验研究 论文 学 生 姓 名:学 号: 专 业 班 级: 学 院: 电气工程学院 指 导 教 师: 开 题 时 间: 2014年3月23日2014年3月23日 一、毕业设计内容及研究意义1.主要内容本课题主要是对基于半屋内GIS配电装置的110kv变电所进行设计。GIS是指六氟化硫封闭式组合电器,国际上称为“气体绝缘金属封闭开关设备”(Gas Insulated Switchgear)简称GIS,它将一座变电站中除变压器以外的一次设备,包括断路器、隔离

2、开关、接地开关、电压互感器、电流互感器、避雷器、母线、电缆终端、进出线套管等,经优化设计有机地组合成一个整体。设计的内容主要包括:负荷分析计算及主变选择、确定电气一次主接线方案、电气主接线设计、短路电流计算、配电装置的配置及主要电气设备的选择和防雷保护及继电保护的配置。2.研究意义随着科技的不断进步,人们的生产生活已经离不开电。提高电力系统的安全可靠性和运行效率具有重要意义。进入21世纪后,我国电力扔将以较高的速度和更大的规模发展,电源和电网将设的任务仍很重,做为发电厂和用户的中间环节,变换和分配电能的重要组成 部分,将面临电力体制改革和技术创新能力的双重挑战,如何合理的设计一个变电所,使之在

3、技术上、管理上适应电力市场化体制和竞争需要,促使电网互联范围的不断扩大,是这次设计的主要目的。2、 研究现状与发展趋势(文献综述)现阶段我国主要进行的变电站典型设计,是通过对现有变电站样本进行评估、类比、组合,形成典型化设计方案,并以新技术为依托,不断优化,形成一系列定制化产品,满足城市、农村电网建设需求。通过变电站典型设计,归并工程流程,统一技术标准,提高工作效率,降低项目实施不确定性,加快工程建设进度,降低将来运行成本。变电站典型设计是将技术与管理相结合,通过典型化、标准化,提高工程整体效益。在过去十多年来。110KV电力网络和变电站在系统中的地位和功能发生了很大变化,110KV电力网络已

4、下降为配电网络,大多数110KV变电站也沦为负荷型的终端变电站。现在国家正在重点发展电网,形成全国统一的联合电网。目前一些发达国家的电能极度紧缺,电力资源紧缺是制约他们发展的一个重要因数。为了满足需求这些国家通过各种方式来降低电能的损耗,比如说增高电压就是一种比较方便、实用的方法,这些国家已经形成了比较完善的变电设计理论。比较完善的变电站设计理论是真正做到了节约、集约、高效等特点。总之,发达国家通过改善变电站结构,降低变电站功率损耗,尽可能地提高变电所的灵活性,最终达到提高经济性的目的。三、研究方案及工作计划1.方案研究经过对电力系统分析、高电压技术、发电厂电气部分、继电保护系统、电力工程概论
