摘要:排水系統(tǒng)是一個(gè)城市不可缺少的重要基礎(chǔ)設(shè)施，也是城市水污染防治和排澇、防洪的骨干工程。它的正常運(yùn)行直接影響到一個(gè)城市社會(huì)經(jīng)濟(jì)的發(fā)展、生態(tài)環(huán)境的保護(hù)和人們的正常生活。在城市排水系統(tǒng)中，為了避免出現(xiàn)因水位過高而外溢的現(xiàn)象，必須對(duì)城市排水系統(tǒng)各級(jí)泵站的運(yùn)行進(jìn)行合理調(diào)度。根據(jù)相似性原理，用直流電路模型對(duì)城市排水系統(tǒng)水位控制進(jìn)行仿真，以構(gòu)建輔助等效排水系統(tǒng)。其中，結(jié)點(diǎn)水位對(duì)應(yīng)于等效直流電路中的節(jié)點(diǎn)電位，管道的阻值系數(shù)對(duì)應(yīng)于等效直流電路中邊上的電組，而水泵的揚(yáng)程則對(duì)應(yīng)于等效直流電路中相應(yīng)邊上的電動(dòng)勢(shì)。運(yùn)用基爾霍夫定律構(gòu)建水流平衡方程式。通過水位控制的迭代算法，可以模擬得出在兩個(gè)結(jié)點(diǎn)間是否需要安裝水泵，或需要安裝多大揚(yáng)程的水泵，以達(dá)到設(shè)計(jì)的成本低、周期性短的目的。 關(guān)鍵詞：城市排水系統(tǒng)；計(jì)算機(jī)仿真；直流電路模型
Abstract:The drainage system is indispensable infrastructure of a city, key projects of urban water pollution control and drainage, flood control. The normal operation of a direct impact on an urban social and economic development, protection of ecological environment and people's normal life. In the urban drainage system, in order to avoid the spillover phenomenon due to the water level is too high, you must run the pumping stations at all levels of the urban drainage system reasonable dispatch. According to the similarity principle, the DC circuit model of the urban drainage system, water level control simulation, to build the auxiliary equivalent drainage system. Which nodes the water level corresponding to the equivalent DC circuit node potential pipeline resistance coefficient corresponds to the equivalent DC circuit in the edge of the electric group, the pump head corresponds to the corresponding edge of the equivalent DC circuit electromotive force. Using Kirchhoff's law to build the water balance equation. Level control of the iterative algorithm can simulate drawn between two nodes need to install the pump, or the need to install much lift pump, in order to achieve the design of low-cost, short cyclical purposes. Key words：Urban drainage systems; computer simulation; DC circuit model
