【摘要】:為了對城市管道漏失進(jìn)行有效控制,根據(jù)壓力驅(qū)動漏失水力模型結(jié)合夜間最小流量法,確定管網(wǎng)節(jié)點(diǎn)的漏失系數(shù),建立考慮壓力引起漏失量的改良水力模型——減壓閥經(jīng)濟(jì)效益模型.該模型使用遺傳算法進(jìn)行求解,以管道漏失量最小化為目標(biāo)函數(shù),以減壓閥最大安裝數(shù)量、節(jié)點(diǎn)壓力流量方程、最大允許漏失率為約束條件,求出減壓閥安裝數(shù)量及安裝位置,再從所有可行解里面選擇一組花費(fèi)最小的解作為最優(yōu)解.并以HJ分區(qū)為例詳細(xì)討論減壓閥經(jīng)濟(jì)效益模型的求解過程,對實(shí)際的管道漏失控制具有指導(dǎo)意義.
[Abstract]:In order to control the leakage of urban pipeline effectively, the leakage coefficient of pipe network node is determined according to the hydraulic model of pressure-driven leakage combined with the nocturnal minimum flow method. An improved hydraulic model, the economic benefit model of the pressure reducing valve, is established, which takes the leakage caused by the pressure as the objective function and the maximum installation number of the pressure reducing valve, taking the minimization of the leakage of the pipeline as the objective function, and using genetic algorithm to solve the model. The nodal pressure flow equation, the maximum allowable leakage rate is the constraint condition, the installation quantity and the installation position of the pressure reducing valve are obtained. Then a group of least cost solution is selected as the optimal solution from all feasible solutions, and the process of solving the economic benefit model of pressure reducing valve is discussed in detail by taking HJ partition as an example, which is of guiding significance to the actual pipeline leakage control.
