1.1 中文摘要

本毕业设计承担水利水电枢纽工程中水电站厂房设计的部分工作。

根据已有的原始资料和该处地形图进行设计，主要内容有：水电站站址的选择，总体布置，水轮机型号的选择，蜗壳尺寸的确定，尾水管尺寸的确定，调速器和蝶阀的型号选择，水电站厂房尺寸的确定，尾水渠渠道布置、形式选择、开挖方量等，并根据要求绘制相应的平面布置图和剖面图。

水电站位于河南省西峡县境内，位于丹江支流老灌河上，水力资源丰富，可供修建大中型水库和电站，流域下游为该县的主要产粮区和工业发展区。由于受电力不足的影响，严重制约了该地区的经济发展，为了解决该地区的用电紧张问题和合理开发老灌河水力资源，拟定修建水利水电枢纽工程，以发电为主，结合防洪，城市供水，农田灌溉及水产等进行综合利用。

本电站的设计水头为29.24米，单机容量3200kW，共三台机组，总装机容量9600kW。 关键词：峰荷、装机容量、效率、水库、发电机、水轮机。
