| 摘 要： | 根据红枫水库的具体情况,依据1994年国家颁布的《防洪标准》(GB50201-94)和2000年中华人民共和国水利部颁布的《水利水电工程等级划分及洪水标准》(SL252-2000),基于现有的工程条件和技术资料,从设计洪水推求、水库自身防洪调度和安全运行、蓄满率变化、电站发电效益分析等方面,科学合理地分析论证红枫水库汛期前期(5~7月)限制水位抬高的可行性和必要性。研究结果表明:按照水库的现行调洪原则,库水位从1236.8m起调,其相应调洪成果满足要求,且有一定的安全余度。从发电效益来看,最大年均增发电量为0.044亿kW.h,提高幅度为6.8%左右,其经济效益显著。

| Abstract: | According to "Standards of Flood Control",issued by People's Republic of China in 1994,and "Ranking and Flood Standard of Water Resources and Hydropower Engineering ",issued by Ministry of Water Resources in 2000,the flood control limited level of Hongfeng reservoir during the former flood season were studied based on the present current engineering conditions and technical data.This paper probed into the feasibility and necessity of driving up flood control limited level of Hongfeng reservoir from May to July in such aspects as inquiring into design flood,dispatching of flood control and safety operation of reservoir,changing of fill storage ratio of reservoir and power generation benefits analysis.The results showed that in accordance with current principle if the limiting water level was drove up from 1236.8m it can satisfy the requirement and also has a certain safety margin.And the benefits were remarkable with an increase of 4.4kW·h and rate of 6.8%. |
