白莲崖水电站水能规划及调度图绘制-说明书

水利水电工程专业毕业设计I摘要白莲崖水库坝址位于漫水河中游，距淠河入口189km，属于年调节水库。水电站以发电为主，兼顾航运、放木(竹)及防洪等综合利用要求。白莲崖水电站挡水建筑物为混凝土重力坝，坝址处于漫水河，坝址处河谷狭窄，两岸地形对称，岩石坚硬完整，为单一的花岗斑岩，地质状况良好。大坝正常蓄水位为208m，对应库容为2.005亿m³。坝址处多年月平均流量为19.5m³/s。通过计算可知，白莲崖水电站水库为年调节水库。本次设计给定了水库正常蓄水位为211m，由于水库多年平均来水量较少，通过水量调节平衡计算，将正常蓄水位下调至208m。对三个拟定的死水位方案（179m，181m，183m）进行兴利调节及水能计算，经计算比较，选保证出力大的179m死水位为最终方案，对应库容0.55亿m³。调洪演算时取防洪限制水位为207m。根据下游防护标准（P=1%），确定水库的防洪高水位208.61m，根据洪水资料设计洪水（P=0.2%），确定水库的设计洪水位211.64m。校核洪水位（P=0.1%）为212.02m。白莲崖水电站重力坝非溢流坝段坝顶高程215m，最大坝高82m，坝底宽68m。溢流坝段堰顶高程202m，溢洪道净宽60m，闸门采用平板闸门10.3（宽）×7（高），闸墩长14.5m，厚3m，溢洪道总长78m，坝底宽为85.8m。大坝挡泄水建筑物轴线总长300m。利用电力电能平衡的方法确定水电站装机容量为8.6万kW，两台机组，单机容量4.3万kW。水轮机型号为HL220-LJ-380；厂房为坝后式厂房，主厂房总宽定为20m，总长55m。水轮机安装高程为139.845m。起重机选用电动双钩桥式起重机，最大起重量选2×150吨，跨度选用16m。装配场长度取20m。副厂房是为保证水电站正常运行需要，设置在主厂房下游侧。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。副厂房总宽6.6m。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。关键词：兴利调节；调洪演算；水库调度；挡水建筑物；泄水建筑物；稳定计算；应力计算；水轮机选型；厂房设计。水利水电工程专业毕业设计IIABSTRACTBailianyaReservoirislocatedinthemidstreamofManshuiRiverwhichis189kmawayfromtherivermouthofPeariver.Itisanannualregulationreservoir.Thishydroelectricpowerstationismainlydesignedforgeneratingelectricity.Itgivesconsiderationtoshipping,transportingwoodandpreventingwaterfloodaswell.ThewaterretainingstructureofBailianyahydroelectricstationisaconcretegravitydam.ThedamsiteisatManshuiRver.Thevallyatthatlocalityisappropriatelynarrow.Theterrainoftworiversidesissymmetrical.Therockissimplycomposedofgraniteporphyrywhichissolidandcomplete.Sothegeologicalconditionisgood.Thisdam’snormalwaterlevelis208m,anditscorrespondingstoragecapacityis0.2billioncubicmetres.Themonthlyaveragerateofflowis19.5cubicmetrespersecondatthedamsiteduetolong-termstatistics.Itisanannualregulationreservoirbycalculation.Inmygraduationprojecttheimpoundedlevelwasoriginallydesignedtobe211m.Becausethisreservoirgotlittlewatersupplementannually,thenormalwaterlevelwasreducedtobe208maccordingtothecalculationofwaterequilibriumregulation.Byprofitingregulationandwaterpowercalculation,the179m-deadwaterlevelwaseventuallychosenfromthreedraftdeadwaterlevelschemes(179m,181m,183m)becauseitsensuringoutputisthelargestone.Thecorrespondingstoragecapacityis55millioncubicmetres.Thefloodcontrolwaterlevelwasdesignedtobe207m.Onthebasisofprotectionstandardofdownstreamstructures(P=1%),theupperwaterlevelforfloodcontrolwasdesignedtobe208.61m.Accordingtothedataofthedesignflood,thedesignfloodlevelwasdesignedtobe211.64m.Accordingtothedataofthecheckflood,themaximumfloodlevelwasdesignedtobe212.02m.Thecrestaltitudeofthenon-overflowdamsectionofBailianyahydroelectricstationis215m.Itsmaximumheightis82metres.Thebaseofthedamis68metreswide.Thealtitudeoftheweircrestoftheoverfalldamsectionis202m.Theclearwidithofthespillwayis60metres.Thesluicegateis10.3metreswideand7metreshigh.Thegatepieris14.5metreslongand3metresthick.Theoveralllengthofthespillwayis78metres.Thebaseoftheoverflowdamis85.8metreswide.Theoveralllengthofthewaterretainingstructureis300metres.Bycalculatingthebalanceoftheelectricenergybalance,theinstalledcapacityofthehydroelectricstationwasdesigndtobe86thounsandkW.Itwasdividedinto水利水电工程专业毕业设计IIItwounitswhoseunitcapacitywas43thousandkW.ThemodelofthewaterturbineisHL220-LJ-380.Thefactorybuildingwasdesignedtobethedamtype.Itsmainfactorywasdesignedtobe20metreswideand55metreslong.Theinstallationaltitudeofthewaterturbinewas139.845m.Theelectricaldoublehookbridgecranewaschosen.Itsmaximumhoistingcapacityis2×150t.Thespanwaschosentobe16metres.Theassemblyplantwasdesignedtobe20metreslong.Theauxiliaryroomwasdesignedatthedownstreamsideofthemainfactoryforensuringthatthestationwasworkingregularly.Itmainlycontainedvariousofelectromechanicalaids,manufacturingshopsandsomenecessarydomesticinstallationrooms.Theauxiliaryroomwas6.6metreswide.ThiselectricalstationwilljointheEastChinaPowerGridaftertheconstructionworkisfinished.Furthermore,theconstructionofthestationwilldrivethelocalagricultureintofurtherdevelopmentandcreatemoreemploymentopportunitiesforlocalresidents.Itwillimprovethesocialeconomyandpromotelocalareaanditssurroundingareas’furtherdevelopment.Keywords：gravitydam;profitingregulation;hydropowercomputation;energybalance;waterretainingstructure;sluicingbuildings;stabilization;waterturbine;factorybuilding水利水电工程专业毕业设计IV水利水电工程专业毕业设计V目录摘要....................................................................................................................................................IABSTRACT..........................................................................................................................................II第一章绪论.......................................................................................................................................11.1基本资料.......................................................................................................................................11.1.1流域概况.............................................................................................................................
