1、水利水电工程专业毕业设计摘要乌溪江水电站座落于浙江省乌溪江,湖南镇,属于梯级开发电站,根据地形要求,其开发方式为有压引水式。坝区地质条件较好,主要建筑物(砼非溢流坝),泄水建筑物(砼溢流坝),引水建筑物(有压引水遂洞,调压室),地面厂房。3水库设计洪水位238m(千年一遇),相应的下泄流量6000m/s;校核洪水位3241m(万年一遇),相应的下泄流量9700m/s;正常挡水位231m.本设计确定坝址位于山前峦附近,非溢流坝坝顶高程242.3m。坝底高程106m。最大坝高130.3m。上游折坡坡度1:0.10,下游坝坡坡度1
2、:0.77,溢流坝堰顶高程224.2m。引水遂洞进口位于坝址上游凹口处,遂洞全长1100m。洞径8.7m,调压室位于厂房上游280m左右处,高程180m的山峦上,型式为差动式。厂房位于下游荻青位置。设计水头92.91m,装机容量5×4=20万kw,主厂房净宽17.4m,总长59.50m。水轮机安装高程115.66m,发电机层地面高程128.03m,装配场层地面高程129.95m,校核尾水位129.45m。厂房附近布置开关站,主变等。受地形限制,尾水平台兼作公路用,坝址与厂区通过盘山公路连接,形成枢纽体系。由此可见,本设计是合
