1、“调水工程”第二级水电站厂房设计摘要二郎坝水电站位于陕西省宁强县境内，是一项中型跨流域调水工程，具有灌溉、发电、工业供水等综合利用效益。是引嘉入汉水梯级水电开发的第二级水电站，由一级天生桥电站尾水穿过5.63km隧洞至二郎坝乡黄家湾，建二郎坝二级电站，设计水头60.90m，设计流量14.5m3/s，装机容量0.75万kW，年发电量2971万kW·h，二级电站尾水穿过分水岭隧洞，经4.77km隧洞引水至卧龙台，建三级卧龙台电站，二郎坝水电工程充分利用了水资源的优越条件。龙头水库调节性能好，库容7760万m3，年调节水量2.14亿m3，水量利用率可达89%；电
2、站利用水头高，梯级电站总水头高达418m，为发电、灌溉、供水提供了可靠的保证。在本次毕业设计中，应完成的主要工作量为完成水轮机及发电机和蜗壳，尾水管的选型，厂房的布置及尺寸确定，设计要合理，布局要紧凑。关键词：引嘉入汉梯级水电调水工程跨流域5ErlangabdesignofCascadedHydropowerStationABSTRACTThedamhydropowerstationislocatedintheterritoryofNingqiangCountyinShaanxiProvince,itisamedium-sizedinterbasinwat
