1、观音阁水电站工程设计TheEngineeringDesignofGuanyingeHydropowerStation(说明书)学院(系):专业:学生姓名:学号:指导教师:评阅教师:完成日期:2011-5-30观音阁水电站工程设计说明书摘要太子河为辽河下游东侧一大支流。太子河流域的多年平均径流量约46亿m³,为辽河诸支流中水量最丰富的河流。本流域洪水系由暴雨产生,次数频繁,陡涨陡落,洪峰特大,加之太子河沿岸提防较薄弱,防洪安全泄量有限,导致本河沿岸洪涝灾害严重。为了解决太子河流域防洪、除涝,工业及城市用水,灌溉用
2、水及发电等要求,在太子河干流修建观音阁水库。观音阁水电站工程设计的内容包括径流调节和水能计算、水轮发电机组的选择、洪水调节、坝体设计、水电站厂区厂房布置、安装间楼板结构计算。通过计算可得观音阁水库的兴利库容为,正常蓄水位为;选择的水轮机的型号为HL240-LJ-180,发电机型号为SF8-12/312;设计洪水位为,校核洪水位为;坝体由挡水坝段、溢流坝段和电站坝段组成,溢流坝段坝体采用挑流消能型式;水电站厂房采用坝后式厂房形式,电站厂区主要包括主厂房、副厂房、尾水渠、主变压器、高压开关站和对外交通线等;安装间采
3、用梁格式结构布置,并为转子检修设置了水平圆弧梁,梁下有八个支柱。关键词:径流调节;水轮发电机组;洪水调节;厂房布置;楼板配筋-I-观音阁水电站工程设计说明书TheEngineeringDesignofGuanyingeHydropowerStationAbstractTaiziRiverisabigbranchofLiaoheRiver,itliesintheeastsideofthedownstream.Themulti-annualmeanamountofrunoffofTaiziRiverbasinisa
