Study on optimization of pre-flood water level centralized flow control mode of Three Gorges Reservoir
摘要
Abstract
[Objective]Affected by the uncertainty of water forecast,power generation scheduling,ecological scheduling test,and bank stability requirements,the centralized water level scheduling mode of the Three Gorges Reservoir has some problems,such as difficulty in precise water level regulation and room for optimization of water resource utilization efficiency.In order to effectively control the flood control risk and improve the operation flexibility and comprehensive benefit,the optimal operation mode of extending the pre-flood period of the Three Gorges Reservoir was proposed.[Methods]Based on the analysis of the changes of hydrological regime in the Three Gorges Reservoir,the flood control effects and benefits of different schemes were compared and analyzed through the coupling of the extension of pre-flood centralized water level,the flood control calculation and the flood evolution model of the downstream river.Under the principle of not affecting the safety of flood control and effectively improving the comprehensive benefit,the pre-flood water level centralized subsiding method was optimized.[Results]The result show that the Three Gorges Reservoir can pre-discharge the water level to 145 m when it is transferred to flood control operation in 1954,1998 and other major floods in the Yangtze River basin,and the pre-discharge process does not increase the number of days beyond the warning water level of major hydrological stations such as Shashi and Chenglingji downstream,and do not raise the water level during flood peak.[Conclusion]On the premise that the flood control risk can be controlled,when the downstream river water level is low in mid to late June,the pre-flood water level of the Three Gorges Reservoir can be appropriately extended to 145 m,which can better coordinate the pre-flood flood control and water supply needs,and effectively connect the dynamic control of the reservoir's operating water level during the flood season,which is conducive to improving the flexibility of the centralized flood control and water resource utilization efficiency,and provide better conditions for the actual operation of the Three Gorges reservoir..关键词
