洗马河二级赛珠水电站引水系统设计回顾

Review on design of headrace system of Ximahe River Ⅱ Saizhu Hydropower Station

洗马河二级赛珠水电站引水系统具有水头高、洞线长、地震烈度高及地质条件复杂等特点。为此,对隧洞、活断层带及压力钢管进行了合理的结构设计,同时,对排水系统也采用了按部位分独立单元设计以提高排水效果,从而达到了既经济又安全的目的。机组并网发电以来,至今运行良好。本文系统地对该电站设计中一系列关键技术问题进行了回顾,可为同类工程设计借鉴。

The headrace system of Ximahe River Ⅱ Saizhu Hydropower Station has the characteristics of high head,long tunnel length,high seismic intensity,complicated geological condition,etc. Therefore,reasonable structural designs are made for the tunnel,active fault zone and penstock,meanwhile,the drainage system is also designed into several independent units for improving the drainage effect therein,thus the target of that it is not only economic,but also safe is got. Since the grid-connection of the power generating units,the operation of the hydropower station is hitherto excellent. A series of key technical problems are systematically reviewed herein,which can provide some references for the similar projects concerned.
