文档介绍：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。m（千年一遇），相应的下泄流量m3/s；校核洪水位m（万年一遇），相应的下泄流量m3/s；正常挡水位23m.
本设计确定坝址位于山前峦附近，非溢流坝坝顶高程24m。坝底高程115m。最大坝高1m。上游坝坡为折坡，折坡度1：，下游坝坡坡度1：，溢流坝堰顶高程22m。
引水遂洞进口位于坝址上游凹口处，遂洞全长L=1m。洞径D=，调压室位于厂房上游228右处，高程251m的山峦上，型式为差动式调压室。
厂房位于下游荻青位置。设计水头 m，装机容量3×kw=万kw，主厂房净宽 m，总长 m。，发电机层与装配场层同高，其高程为 m（比下游校核洪水位高 m）。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。
另外，本设计还专门对调压室进行水利计算和结构计算。
由此可见，本设计是合理可行的
Abstract
The Wuxijiang hydropower station is located in HuNan Town in ZheJiang province ,which belongs to a chain of exploitation .
According to the demand of topographic form ,I choose diversion hydropower station . The geology condition is good .The main construction conclude the water retaining structure (the concrete non –over-fall dam) ,the release works (the concrete over–fall dam) ,the diversion structure (pressure seepage tunnel ,the surge-chamber ) ,and the surface power station .
The design water level is m ,its corresponding flow amount is 5400m3/s .The check level is ,its corresponding flow is 9700m3/s .The regular water retaining level is m .
The dam site is near the former saddle .The crest elevation of the non-over-fall dam is m ,and the base elevation is ,The max height of the dam is m , ,the spillway crest elevation is
m .
The inducer of the seepage tunnel is located at the recess place ,The length of tunnel is m ,the diametric of which is 8 m .The surge-chamber is located at the mountain , which is about m from the work shop building and is type is differential motion.
The workshop building is located at downstream ,the design level of the turbine is m , the equipped capacitor is 17×104kW ,the clean width is m , its whole length is m . The fix level of the turbine is m , and the height of dynamo is 12m . Near the workshop building , there are switch station and the main transformer and so on .
addition, the d
