【摘要】：為解決黃河上游龍劉水庫(kù)(龍羊峽、劉家峽水庫(kù))在聯(lián)合運(yùn)用過程中各行業(yè)用水導(dǎo)致的劉家峽水庫(kù)汛前水位過低、影響水庫(kù)綜合效益的問題,從改善非汛期龍劉水庫(kù)聯(lián)合運(yùn)用方式的理念出發(fā),以黃河上游梯級(jí)水庫(kù)群防洪、防凌、供水、灌溉、發(fā)電等生產(chǎn)實(shí)踐的經(jīng)驗(yàn)和大量技術(shù)研究成果為基礎(chǔ),構(gòu)建基于全河水量調(diào)配的多目標(biāo)優(yōu)化調(diào)度模型,對(duì)比分析并確定了非汛期龍劉水庫(kù)聯(lián)合控制水位閾值,在此基礎(chǔ)上研究提出了龍劉水庫(kù)非汛期聯(lián)動(dòng)補(bǔ)水機(jī)制:在達(dá)到控制水位閾值條件下,由龍羊峽水庫(kù)優(yōu)先承擔(dān)供水任務(wù),并向劉家峽水庫(kù)補(bǔ)水至控制水位。分析結(jié)果表明:提出的龍劉水庫(kù)非汛期聯(lián)動(dòng)補(bǔ)水機(jī)制,在不改變現(xiàn)狀全河水量配置效果的情況下,將提升龍羊峽、劉家峽乃至整個(gè)上游梯級(jí)水庫(kù)的年均發(fā)電量,且劉家峽水庫(kù)非汛期發(fā)電量增幅明顯。
[Abstract]:In order to solve the problem that the water level of the Liujiaxia reservoir in the upper reaches of the Yellow River is too low before flood, which affects the comprehensive benefit of the reservoir, the water level of the Liujiaxia Reservoir caused by the water used by various trades in the process of joint operation is too low. Based on the idea of improving the combined operation mode of Longliu Reservoir in the non-flood season, and based on the experience of production practice and a large number of technical research results of flood control, flood prevention, water supply, irrigation and power generation in the cascade reservoirs in the upper reaches of the Yellow River, A multi-objective optimal dispatching model based on the water allocation of the whole river is constructed, and the combined control water level threshold of the Longliu Reservoir in non-flood season is analyzed and determined. On this basis, the mechanism of non-flood season water supply in Longliu Reservoir is studied. Under the condition of reaching the threshold of the controlled water level, the Longyangxia Reservoir takes on the water supply task first, and supplies water to the Liujiaxia Reservoir to control the water level. The analysis results show that the proposed mechanism of non-flood season combined replenishment of Longliu Reservoir, without changing the effect of water allocation of the whole river, will increase the average annual power generation of Longyangxia, Liujiaxia and even the whole upstream cascade reservoir. And the Liujiaxia reservoir non-flood period electricity production increase is obvious.
