【摘要】：我國(guó)是一個(gè)水資源短缺的國(guó)家,人均淡水資源甚少,水資源分布也極其不均。南水北調(diào)工程是我國(guó)水資源優(yōu)化配置、解決北方地區(qū)缺水問(wèn)題的重要戰(zhàn)略性基礎(chǔ)設(shè)施工程。東線工程是南水北調(diào)工程總體布局“四橫三縱”基本框架中的重要組成部分,其泵站的特點(diǎn)是揚(yáng)程低、流量大、運(yùn)行時(shí)間長(zhǎng),部分泵站兼有排澇任務(wù),要求泵站運(yùn)轉(zhuǎn)靈活、效率高。但是泵站的運(yùn)行成本是巨大的,它的能耗量在整個(gè)調(diào)水成本中占有很大比重。因此,研究泵站的優(yōu)化運(yùn)行、提高泵站的運(yùn)行效率、降低能源消耗等已成為調(diào)水工程亟待解決的問(wèn)題。 金湖站作為東線工程的第二梯級(jí)泵站,對(duì)其優(yōu)化運(yùn)行進(jìn)行研究,將有著顯著的節(jié)能效果,這對(duì)提升泵站的管理與建設(shè)水平,節(jié)省泵站的運(yùn)行費(fèi)用,提高有限能源的利用率有較大意義,因此,具有較好的應(yīng)用前景,并將帶來(lái)一定的社會(huì)經(jīng)濟(jì)和生態(tài)效益。 本文針對(duì)金湖站的特性,主要研究了以下幾方面內(nèi)容： (1)以金湖站站內(nèi)單機(jī)組為研究對(duì)象,考慮峰谷電價(jià),以機(jī)組運(yùn)行費(fèi)用最少為目標(biāo)函數(shù)(單純指耗電費(fèi)用),一定時(shí)段內(nèi)的提水總量、機(jī)組功率和開(kāi)停機(jī)次數(shù)為約束,通過(guò)建立金湖站單機(jī)組葉片全調(diào)節(jié)優(yōu)化運(yùn)行模型,采用動(dòng)態(tài)規(guī)劃法對(duì)泵站單機(jī)組優(yōu)化運(yùn)行方法進(jìn)行研究,并將其與額定運(yùn)行時(shí)的結(jié)果進(jìn)行比較分析,優(yōu)化效果良好。 (2)以金湖站站內(nèi)多機(jī)組(同型號(hào))為研究對(duì)象,考慮峰谷電價(jià),以泵站機(jī)組運(yùn)行費(fèi)用最少為目標(biāo)函數(shù)(單純指耗電費(fèi)用),一定時(shí)段內(nèi)的提水總量、機(jī)組功率和開(kāi)停機(jī)次數(shù)為約束,通過(guò)建立金湖站站內(nèi)多機(jī)組(同型號(hào))葉片全調(diào)節(jié)優(yōu)化運(yùn)行模型,采用試驗(yàn)選優(yōu)法和動(dòng)態(tài)規(guī)劃逐次逼近法兩種方法求解,分別與額定運(yùn)行結(jié)果進(jìn)行了對(duì)比分析,并對(duì)兩種方法優(yōu)化結(jié)果進(jìn)行了比較,可為該條件下我國(guó)大型泵站優(yōu)化運(yùn)行提供參考。 (3)以Intel Visual Fortran編譯器為程序開(kāi)發(fā)平臺(tái),開(kāi)發(fā)了金湖站優(yōu)化運(yùn)行方案查詢系統(tǒng)軟件。該查詢系統(tǒng)的開(kāi)發(fā),可為管理操作人員在揚(yáng)程變化時(shí),快速做出優(yōu)化運(yùn)行決策方案提供方便,提高工作效率,節(jié)約資源。
[Abstract]:China is a country short of water resources, the per capita fresh water resources are very few, and the distribution of water resources is extremely uneven. The South-to-North Water transfer Project is an important strategic infrastructure project to optimize the allocation of water resources and solve the problem of water shortage in northern China. The East Route Project is an important part of the general layout of the South-to-North Water transfer Project. The characteristics of the pumping station are low lift, large discharge, long running time, and some pumping stations have the task of drainage, which requires the pumping station to operate flexibly. High efficiency. But the operating cost of pumping station is huge, its energy consumption occupies a large proportion in the whole water transfer cost. Therefore, to study the optimal operation of pumping station, to improve the efficiency of pumping station, to reduce energy consumption has become an urgent problem to be solved in the water transfer project. Jinhu Station, as the second cascade pumping station of the East Route Project, will have remarkable energy-saving effect by studying its optimal operation, which will improve the management and construction level of the pumping station and save the operating cost of the pumping station. It is of great significance to improve the utilization rate of limited energy, therefore, it has a good application prospect and will bring certain social economic and ecological benefits. According to the characteristics of Jinhu station, this paper mainly studies the following aspects: (1) taking the single unit in Jinhu station as the research object, considering the peak and valley electricity price, taking the minimum operating cost of the unit as the objective function (simply referring to the cost of electricity consumption), The total amount of water lifting, the power of the unit and the times of opening and stopping are the constraints in a certain period of time. By establishing the optimal operation model of the blade of the single unit in Jinhu Station, the dynamic programming method is adopted to study the optimal operation method of the single unit of the pump station. The results are compared with the results of rated operation, and the optimized results are good. (2) taking the multi-unit (the same type) in Jinhu station as the research object, considering the peak and valley electricity price, taking the minimum operating cost of the pump station as the objective function (simply referring to the cost of electricity consumption), the total amount of water lifting in a certain period of time. The power of the unit and the times of opening and stopping are the constraints. By establishing the optimal operation model of the blades of the multi-unit (the same type) in Jinhu Station, two methods, the experimental optimization method and the dynamic programming successive approximation method, are used to solve the problem. The results are compared with the rated operation results and the optimization results of the two methods are compared, which can provide a reference for the optimal operation of large pumping stations in China under this condition. (3) based on Intel Visual Fortran compiler, the query system software of Jinhu station's optimal operation scheme is developed. The development of the query system can provide convenience for the manager to make the optimal operation decision scheme quickly, improve the working efficiency and save the resources when the head changes.
