颜家河水电站水文水能计算分析第一章基本资料一、1.1流域概况颜家河水电站位于宝鸡市颜家河乡,是渭河干流陕西境内最上游的水资源开发工程,坝址控制流域面积29348km2。电站站址控制流域面积29950km2。渭河发源于甘肃渭源县乌鼠山,流经甘肃、宁夏、陕西三省26个县(市),全长818km,总流域面积6.24万km2。渭河由宝鸡风阁岭流入陕西境内,于陕西潼关港口东汇入黄河,陕西境内河长502km,流域面积3.32万km2,分别占渭河全长和总流域面积的61.4%和53.2%,是关中地区的主要地表水资源。颜家河水电站以上渭河横跨甘肃、宁夏、陕西三省(区)的天水、定西、平凉、武都、固原、宝鸡六个地区共二十个县(市)。其中甘肃省有渭源、陇西、武山、甘谷、通渭、静宁、漳县、秦安、张川、清水、庄浪、岷县、会宁、临洮、天水市、天水县共十六个县(市),总流域面积25708km2,占林家村以上总流域面积87.59%;宁夏省有西吉、固原、隆德三县,流域面积3250km2,占总面积11.07%;陕西省有宝鸡县几个乡镇,流域面积390km2,占总面积1.3%。该电站以上渭河全长389km,平均比降3.1‰。二、1.2水文资料渭河林家村站于1934年1月设立,原名称太寅站,1959年7月改名为林家村站。测站变动情况为1945年1月太寅站基本断面上迁100m,同年11月又上迁l00m,到1948年又上迁100m,直到1965年元月下迁300m至今。因控制流域面积受基本断面变迁影响不大,故水文资料均可合并统计。至今共有不连续68年径流、洪水、泥沙资料(1934~2001年)。(水文站的控制流域面积为30661km2)该站上游干流有南河川水文站,位于甘肃省天水县南河川乡刘家庄,于1944年设立,控制渭河流域面积23385km2,至今不连续的5926
年径流、泥沙系列。下游有省水文总站设立的魏家堡、黄委会设立的咸阳水文站,它们分别设于1937年、1931年。魏家堡站仅有1946年以后的径流泥沙整编成果。咸阳站控制流域面积37006km2,有1934~2001年不连续的68年径流泥沙系列。由于颜家河水电站无实测资料,根据上述情况,本次水文分析拟以林家村水文测站为参证站,对颜家河水电站进行水文分析。林家村水文站历年逐月径流量资料如附表1,历年最大洪峰流量如附表2。另调查到1933年林家村站发生了一次大洪水,洪峰流量为6890m3/s。相邻各站历次年最大洪峰流量分析计算成果如附表3。一、1.3电站基本情况 颜家河水电站是一个低坝引水式的发电站,坝址设计洪水标准为30年一遇,校核标准为300年一遇;站址设计洪水标准为20年一遇,校核标准为100年一遇。电站设计保证率为75%。拦河坝至压力前池之间采用无压引水隧洞输水。拦河坝坝顶高程为742.00m,无压引水隧洞在引取设计流量情况下的水头损失0.65m。压力前池电站至尾水断面河道的水头损失为0.57m。初选的水轮机效率为0.94;发电机效率为0.92。实测站址处的横断面如图1,该河段的纵比降I=3.407‰,糙率n取0.036。径流洪水资料见附表1,2,3。第二章设计年经流分析计算一、2.1径流资料“三性”审查 林家村水文站具有1941-2001年(30年以上)的实测资料,属于长系列资料,故应对资料进行可靠性、一致性、代表性进行审查,若合理则可应用于颜家河水电站的水文计算。资料可靠性审查 由于林家村水文站的水文资料的测验、采集及处理均符合有关规范,资料精度较高,系列较长,系列完整,故资料具有较高的可靠性。资料一致性审查 应用数理统计的前提是要求统计系列具有一致性,即要求组成系列的每个资料具有一致成因。不同成因的资料不得作为一个统计系列。 将资料按年份整理并且逐年累计得到逐年累计流量,即可作出流量累积曲线进行一致性审查。26
由图可看出该资料的流量累计点线性相关性良好,说明该站流域的气候条件及流下垫面条件基本稳定,所以流量资料具有良好的一致性可以满足要求。资料代表性审查 利用时间跟按时间次序排列的流量Ki-1值由上到下和由下到上的累积值做曲线进行代表性审查。 观察上图可知该系列资料代表性良好。 综上可知,径流系列资料“三性”审查合格,故可用于水文分析计算。26
一、2.2设计年径流频率分析计算 年径流频率曲线、年径流频率计算成果、不同频率年径流的其年内分配过程、日流量~频率历时曲线。 根据水文站所给年平均流量资料,选取皮尔逊Ⅲ型线型进行年径流频率曲线分析计算,计算过程见(附表4)。频率曲线结果如下:将计算得出和最终配线结果所得出的Q均值,Cv,Cs/Cv值及由频率曲线求出的不同频率的年径流量QP记录于表1表1颜家河水电站年径流频率计算成果表不同频率的年径流量QP计算采用计算采用20%25%30%50%70%75%80%85%90%70.7870.780.440.442.593.9987.5982.1365.1851.3447.9244.3740.5136.3二、2.3不同频率年径流量及其年内分配过程已知25%、50%、75%频率下的设计流量QP后,根据所给三个代表年(枯水年、平水年、丰水年)流量资料,算出三个代表年各自的倍比K年=Q年,p/Q年,代,从而可以得出设计年水文站站址处年径流量的分配情况。最后将站址的成果用公式折算后移用到坝址,即可得到坝址的流量年内分配结果如(表2)26

第一章设计洪水分析一、3.1设计洪峰流量频率分析计算将(1933-2000年)68年不连序洪水流量资料进行经验频率分析计算,首先用矩法估计的方法得出计算过程如下:1.计算经验频率将实测系列与特大值系列共同组成一个不连序系列,作为代表总体的一个样本,不连序系列各项可在历史调查期N年内同一排位。在历时调查期N年中有特大洪水a=3项,其中有l项发生在n年实测系列之内;N年中的a项特大洪水的经验频率用下式计算。(3-1)式中PM——特大洪水第M序号的经验频率;M——特大洪水由大至小排列的序号;N——自最远的调查考证年份迄今的年数。实测系列中其余的(n-l)项,则均匀分布在1-PMa频率范围内,PMa为特大洪水第末项Ma的经验频率。实测系列第m项的经验频率计算公式为:(3-2)式中Pm——实测系列第m项的经验频率;m——实测系列由大至小排列的序号;n——实测系列年数。;其中a=3,N=68,n=60,l=22.用矩法计算统计参数。(1)计算洪峰流量的均值:(3-3)26
(2)计算变差系数Cv:(3-4)计算结果(如附表6),得到洪峰流量频率曲线见下图一、3.2计算不同频率下的洪峰流量将据法估算算得出的、、Cs/Cv初始值和最终配线结果所得出的、、Cs/Cv值及由频率曲线求出的不同频率下的年径流量QP记录于表3。表3***(工程名称)洪峰流量分析成果表(m3/s)不同频率洪峰流量QP(m3/s)计算采用计算采用0.10.20.330.5123.35101506.91506.90.80.82.58628.70779.017189.406688.505852.905017.304401.503912.743077.226
第一章水位流量关系曲线距离(m)高程(m)左岸山体坡角右岸路边河槽最低点图1颜家河水电站尾水处河道横断面图根据图1颜家河水电站尾水处河道横断面图,用几何方法计算出不同水位下的相对应的水断面面积A和湿周L,求出水力半径R=A/X,再由曼宁公式:V=(R2/3S1/2)求的V,进而求得不同水位下的流量,计算过程如附表3-1,最后绘出尾水断面水位~流量关系曲线。26
第一章水电站水能分析计算一、5.1日平均出力~频率(历时)曲线根据以算出的颜家河水文站处3个代表年(枯水年、平水年、丰水年)的日平均流量频率计算表数据和水位流量关系曲线,用内插法计算不同流量下对应的下游水位关系,计算结果如附表7,最后绘制平均出力~频率曲线,计算过程如附表8。计算水电站出力的基本公式包含流量和水头两个主要因素。计算公式如下出力计算:N=9.81ηQ电H净(5-1)式中 Q电—发电日平均流量;η—水电站效率。H净—净水头,等于上下游位差扣除水头损失;上游水位742m,水头损失1.22m,上下游水位差出力曲线关系如图。二、5.2出力~多年平均发电量关系曲线多年平均年发电量是指水电站在多年工作时期内,平均每年所能生产的电量。出力差△N=Ni-Ni-1。保证历时T为每年的小时数与时段的累积频率之积。电量差△E等于出力差与相应的保证历时的乘积。多年平均电量等于电量差从下向上依次的累加值,计算过程如附表9,最后绘制出出力~多年平均发电量关系曲线。26
三、5.3装机~装机年利用小时数关系曲线计算装机年利用小时数:h年=E/N,计算结果如附表10绘制装机~装机年利用小时数关系曲线如图:26
第一章水电站装机容量确定装机容量是水电站的重要参数,它反应水电站的规模。水力资源利用程度.电站效益及供电可靠性等。装机容量的选择,应根据用电负荷要求,河流来水等条件经济合理的确定。颜家河水电站是一个低坝引水式的发电站,电站设计保证率为75%,倍比系数C选为3。查出力~多年平均发电量关系曲线图得该水电站的保证出力NP=3.96(千kw),年平均发电量E=32531.8(千kw*h)则其装机容量N装=CNP=3*3.96=11.88(千kw)。故选用三台4000kW的机组,故最后确定水电站的装机容量为N装=4000×3=1.2(万kW)。第二章总结虽然我没有选修水利水能规划这门课程,但在老师和同学的帮助下我还是努力完成了自己的设计。掌握了处理水文数据的方法。对自己的学科有了更深的了解。收获很大。26
