【摘要】：溪洛渡-向家壩-三峽-葛洲壩組成的四庫梯級水庫群是長江上游水能開發(fā)、中下游防洪安全和供水保障體系的重要組成部分,開展四庫多目標(biāo)聯(lián)合優(yōu)化調(diào)度具有重要意義.考慮防洪、發(fā)電和供水3個目標(biāo)建立多目標(biāo)聯(lián)合優(yōu)化調(diào)度模型,采用ε約束法,以四庫梯級總發(fā)電量最大作為主目標(biāo),將防洪、供水等目標(biāo)作為約束條件生成非劣解集;分別選取三峽汛期最高控制水位、最小下泄流量作為防洪、供水約束的情景因子,通過多情景分析,揭示不同來水條件下各目標(biāo)的置換關(guān)系及其機(jī)制.結(jié)果表明:(1)設(shè)置三峽汛期最高控制水位146.5,150,153 m三種情景,其中,相對于146.5 m情景,汛期最高控制水位每提高1 m,多年平均增發(fā)電量約7億kW h,以豐水年增幅最大;(2)最小下泄流量增加10%,四庫總發(fā)電量多年平均降低5億kW h左右;(3)三峽水庫供水保證率受最小下泄流量影響比溪洛渡水庫更為敏感,各種年型下缺水主要集中在枯水期,抬高三峽汛期最高控制水位,不能緩解消落期供水與發(fā)電的矛盾.
[Abstract]:The cascade reservoir group composed of Xiluodu Xiangjiaba three Gorges and Gezhouba is an important part of the water energy development in the upper reaches of the Yangtze River flood control safety and water supply guarantee system in the middle and lower reaches of the Yangtze River. It is of great significance to carry out the multi-objective joint optimal operation of the four reservoirs. Considering the three objectives of flood control, power generation and water supply, the multi-objective joint optimal dispatching model is established. The 蔚 constraint method is used to generate the non-inferior solution set with the maximum total generation capacity of four reservoirs as the main objective and flood control and water supply as the constraint conditions. The maximum controlled water level and the minimum discharge of the three Gorges in flood season are selected as scenario factors of flood control and water supply constraint respectively. The displacement relationship and mechanism of each target under different water conditions are revealed by multi-scenario analysis. The results show that the maximum controlled water level of three Gorges in flood season is 146.5150153 m, which is relative to that of 146.5 m. With the increase of the maximum controlled water level in flood season by 1 m, the average annual output is increased by about 700 million kW / h, the maximum annual increase in abundant water is increased by 10%) the minimum discharge is increased by 10%, and the total output of the four reservoirs is reduced by an average of 500 million kW / h for many years) the water supply of the three Gorges Reservoir is maintained. The permit rate is more sensitive to the minimum discharge than the Xiluodu reservoir. The water shortage is mainly concentrated in the dry season under various annual patterns, raising the maximum controlled water level in the flood season of the three Gorges Project, which cannot alleviate the contradiction between water supply and power generation during the falling period.
