龙滩水电站下游河道疏浚治理工程效益分析

摘要

通过总结龙滩水电站下游河道疏浚治理情况,分析了龙滩水电站不同出库流量时尾水位的变化趋势,并从增加发电量、降低发电耗水率、改善尾水出口流态几个方面对疏浚治理工程进行效益分析.分析结果显示,龙滩水电站下游河道疏浚治理经济效益非常显著.%By summarizing the dredging situation of downstream channel of Longtan Hydropower Station,the changes of tailwater level in different outflows of Longtan Hydropower Station are analyzed,and the benefits of dredging project are also analyzed from the aspects of increasing power generation,reducing water consumption rate of electricity generation,and improving the flow pattern of tail water outlet.It can be seen from analysis results that the economic benefit of downstream channel dredging is very significant.
