毕业设计(论文) 题目名称: 110KV 变电站设计院系名称: 班级: 学号: 学生姓名: 指导教师: 2012 年5月论文编号: 2 110KV 变电站设计 110KV Substation Design 院系名称:电子信息学院班级: 学号: 学生姓名: 指导教师: 2012 年5月 I 摘要本文主要进行 110KV 变电站设计。首先根据任务书上所给系统及线路和所有负荷的参数,通过对所建变电站及出线的考虑和对负荷资料分析,满足安全性、经济性及可靠性的要求确定了 110KV 、 35KV 、 10KV 侧主接线的形式,然后又通过负荷计算及供电范围确定了主变压器台数、容量、及型号,从而得出各元件的参数,进行等值网络化简,然后选择短路点进行短路计算,根据短路电流计算结果及最大持续工作电流,选择并校验电气设备,包括母线、断路器、隔离开关、电压互感器、电流互感器等,并确定配电装置。根据负荷及短路计算为线路、变压器、母线配置继电保护并进行整定计算。本文同时对防雷接地及补偿装置进行了简单的分析,最后进行了电气主接线图及 110KV 配电装置间隔断面图的绘制。关键词:变电站设计,变压器,电气主接线,设备选择 II Abstract This paper design a 110KV substation . Firstly,according to the gaved system , electricity line and the parameters of load ,which provided by the assignment book,through considering the substation which will be built and feeders,analysising load materials,confirming the Main electrical wiring form of 110KV 、 35KV 、 10KV side based on security,economy and reliability,then conform the numbers,volume and type of the main transformer through load calulation and supply district,thus getting the parameters of all ponent,simplify electric circuit,select short point carry on short circuit calculations operation circuit , select and check out electrical equipment , including bus , breaker , disconnect switch , voltage transformer , current transformer and so on,so that conform the distribution relay protection and setting-calculation for the electricity line,transformer and bus according to the load and short the same time,this paper analyse simply lightning protection and grounding ,two pictures be drawed which include Main electrical wiring diagram and 110KV Power distribution equipment sectional drawing interval. KeyWords : Substation design ,T ransformer , Main electrical wiring , Equipment election III 目录 1引言.......................................................................................................................... 1 变电站的作用......................................................................
