水利水电工程专业毕业设计1摘要紧水滩电站在瓯江上游干流梯级开发的第一级水电站,工程以发电为主,兼顾航运、漂木及防洪等综合利用要求。瓯江流域处浙东南沿海山区,属于年调节水库。本次设计的水库死水位为264m,正常蓄水位为284m。根据历史洪水资料设计洪水(P0.1),水库的设计洪水位290.0m。校核洪水位(P0.01)为292.0m。水电站装机容量为20万kW,三台机组单机5.0万kW。水轮机型号为HL220LJ330发电机型号为定做为坝后厂房顶溢流式厂房,开关站布置在左岸。主厂房总宽定为19m,总长73.5m。水轮机安装高程为203.53m。起重机选用电动双钩桥式起重机,最大起重量选2125吨,跨度选用16m。装配场长度取15.5m,进场公路布置在左岸。副厂房是为保证水电站正常运行需要,设置在主厂房上游侧。主要布置各种机电辅助设备、房间、生产间和必要生活设施房间。电站建成后主要担任华东电网调峰并供电丽水、温州将使丽、温两地区通过220千伏输电线路联系,形成浙南电力系统。此外,电站的建设,将带动当地工农业发展,为当地居民创造就业条件,改善当地社会经济,促进当地以及周围地区的发展。紧水滩水电站布置及压力钢管应力计算2AbstractTheJinshuitanhydropowerstationisthefirststephydropowerstationinupperreachesoftheOuJiangRiver.Themainpurposeoftheprojectistogenerateelectricity,butalsoconsideredtheflowingwoodsandthefloodsprotection.OuJiangRiverbasinlocatedinthesoutheastareainZheJiangProvince,andthehydropowerstationisayearadjustreservoirThedesigndeadwaterlevelis264m,andthenormalwaterlevelis285m.AccordingtothehistoricalflooddateP0.1,thedesignedfloodlevelis291.0m,theproofreadlevelis292.0mP0.01.Thetotalelectriccapacityis200,000kW,andthreegenerateswhosecapacityis50,000kWareinstalled.ThetypeoftheturbineisHL220LJ330,andwehavethetypeofthegeneratormadeinorder.Thepowerhouseissituatedundertheoverflowdam.Thewidthofthemainpowerhouseis19m,andthelengthis73.5m.Allkindsofauxiliaryequipmentandotherkindsofroomsareassembledindeputyhouse.Whenthehydropowerstationisconstructed,itwillregulatetheelectricnetworkofthesoutheastofChina,anditalsosuppleelectricitytoLiShuiandWenZhou.Atlast,anetofelectricitywillbeformed.Additionally,theconstructionofthehydropowerstationwillspuronthedevelopmentoftheindustryandagriculturesinthearea.Itwillalsospuronthejobimprovementoftheeconomiccondition.水利水电工程专业毕业设计3目录第一章自然地理及工程地质..........................................................................................51.1流域概况............................................................................................................51.2水文与气候.........................................................................................................51.3地形与地质.........................................................................................................61.3.1水库区工程地质........................................................................................61.3.2坝址地质...................................................................................................71.4天然建筑材料.....................................................................................................71.4.1土料..........................................................................................................71.4.2砂石料......................................................................................................7第二章经济、水利与动能..............................................................................................72.1工程效益............................................................................................................72.2特征水位及机组型号.........................................................................................8第三章机组选型.............................................................................................................83.1特征水位...........................................................................................................83.1.1Hmax可能出现情况.................................................................................83.1.2Hmin可能出现情况...............................................................................103.1.3avH的计算............................................................................................103.2水轮机的选择...................................................................................................113.2.1HL220工作参数确定.................................................................................113.2.2HL200工作参数确定.............................................................................13第四章发电机选型及主要尺寸.....................................................................................154.2外形尺寸(单位cm).................................................................................164.2.1平面尺寸...............................................................................................164.2.2轴向尺寸...............................................................................................16第五章金属蜗壳尺寸...................................................................................................17第六章尾水管尺寸......................................................................................................17第七章调速器及油压装置选择与尺寸..........................................................................187.1调速功计算水轮机的调速功.........................................................................187.2接力器选择.....................................................................................................187.2.1接力器直径ds........................................................................................187.2.2最大行程...............................................................................................187.2.3接力器容积计算................................
