摘要
枕头坝一级水电站尾水河道1.1 km范围,淤积严重,抬高了下游尾水位,大大影响了电站发电效益。通过采用抓斗式和铲斗式相互配合的清淤方式在枕头坝一级水电站下游河段开展两个枯水期的疏浚施工和试验研究,以期达到降低下游水位的目标,并探索枕头坝二级水电站采用下游河道清淤充分利用下游3 m水头以增大装机容量的可行性。本次清淤有效降低了下游河道水位,提高了发电效益,为大渡河流域同类电站通过下游河道疏浚提高水能利用效率提供了技术支持。
The tailrace channel of Zhentouba Hydropower StationⅠis within 1.1 km,which is seriously silted up,raising the downstream tailrace level and greatly affecting the power generation efficiency of the power station.The dredging construction and experimental study were carried out in the lower reaches of Zhentouba Hydropower StationⅠin two low water periods by using the dredging method of bucket and grab,In order to achieve the goal of lowering the downstream water level,and explore the feasibility of using the downstream river channel desilting to make full use of the downstream 3 M water head to increase the installed capacity of Zhentouba Hydropower StationⅡ.This dredging effectively reduces the water level of the downstream river,improves the power generation efficiency,and provides technical support for similar hydropower stations in Dadu River basin to improve the water energy utilization efficiency through dredging of the downstream river.
