1、“调水工程”第二级水电站厂房设计—毕业设计论文“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
2、好,库容7760万m3,年调节水量2.14亿m3,水量利用率可达89%;电站利用水头高,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ErlangabdesignofCascadedHydropowerStationABSTRACTThedamhydropowerstationislocatedintheterritoryofNingqiangCoun
