大渡河猴子岩水电站设计 电气工程专业

摘 要猴子岩水电站位于四川省甘孜藏族自治州康定县孔玉乡，是《四川省大渡河干流水电规划调整报告》推荐的 22 级开发方案中的第 9 个梯级。电站采用坝式开发。其水库长约 48km，总库容 9.571 亿 m3，兴利库容 5.07 亿 m3，属高山峡谷河道型水库。水库正常蓄水位 1852.0m，汛限水位 1842.0m，极限死水位 1812.0m。猴子岩水电站位于大渡河干流上游河段，属天然不通航河段，远景规划亦无通航要求，并且没有供水、灌溉和防洪要求。因此电站的开发任务为发电。电站总装机容量 1600MW，共 6 台机组，多年平均年发电量 76.35 亿 kWh。设计最终决定采用 HL160 型混流式水轮机，与其匹配的发电机型号为 SF300-20/1207。机组额定转速为 150r/min，额定水头为 142.0m，额定流量为 240.1m3/s。根据调洪演算的结果，最后确定坝顶高程为 1858.09m。泄水建筑物包括两条泄洪洞，一条溢洪洞和一条放空洞。每两台水轮机共用一条引水隧洞，三条引水隧洞相邻布置在左岸。经过计算，必须设置上游调压室，调压室直径为 34.0m。水电站主要包括主厂房、副厂房、主变压器场、开关站、尾水渠等。主厂房总长 195.62m，宽 32.60m，发电机层地面高程 1700.0m。吊车梁采用 T 型截面，属超静定结构。计算表明吊车梁能满足承载能力和正常使用的要求。关键词：枢纽布置；水电站；水轮机；吊车梁- Ⅱ -Design for Houziyan hydropower station at Dadu RiverAbstract The Houziyan hydropower station is located in Kongyu, Kangding County, Ganzi Tibetan autonomous Prefecture, Sichuan Province. It is the ninth of 22 development programs, recommended by the Report of Adjusting Hydropower Plan about Dadu River in Sichuan. It is a dam-type hydroelectric station, and its reservoir is about 60km long, with 957 million m3 total reservoir capacity and 507 million m3 utilizable capacity. So the reservoir is belong to alpine canyon channel type. The normal, limited and extreme dead water level are 1852.0m, 1842.0m and 1812.0m respectively. The station is located in the upper reaches of Dadu River, a natural unnavigable river. There will be no demand for navigation, w...
