【摘要】：隨著西氣東輸、川氣東送等工程的建設(shè)和投產(chǎn),一個(gè)全國(guó)性的大型輸氣管網(wǎng)系統(tǒng)正在逐步形成,對(duì)管道運(yùn)行調(diào)度的要求也在逐步提高。目前,國(guó)內(nèi)天然氣管道的運(yùn)行管理大多依靠經(jīng)驗(yàn)。雖然在大多數(shù)情況下運(yùn)行方案是可行的,但也具有一定的優(yōu)化空間。從節(jié)能減排和降低運(yùn)行費(fèi)用的角度分析,輸氣管道運(yùn)行優(yōu)化的意義重大。本文通過實(shí)例算例分析,結(jié)合仿真和優(yōu)化兩大模塊,結(jié)合動(dòng)態(tài)規(guī)劃算法對(duì)天然氣管道的多目標(biāo)運(yùn)行優(yōu)化技術(shù)進(jìn)行研究。通過以上所述的研究,首先建立西氣東輸二線的穩(wěn)態(tài)仿真優(yōu)化模型,將仿真模塊得出的仿真工況與SPS軟件的仿真工況結(jié)果進(jìn)行比對(duì)驗(yàn)證其準(zhǔn)確性,之后編寫天然氣管道多目標(biāo)運(yùn)行優(yōu)化的軟件,使其具有自定義仿真和多目標(biāo)最優(yōu)化方案計(jì)算(能耗最小,壓縮機(jī)開機(jī)臺(tái)數(shù)最少)的功能。在特定的工況下計(jì)算出西氣東輸二線管道多目標(biāo)優(yōu)化運(yùn)行方案,將其與實(shí)際運(yùn)行方案進(jìn)行比對(duì)。文章在單目標(biāo)優(yōu)化的基礎(chǔ)上更上一層樓,對(duì)多目標(biāo)優(yōu)化開始研究,使得天然氣管道運(yùn)行優(yōu)化在實(shí)際生產(chǎn)中的應(yīng)用更加有意義,更加具有代表性,也對(duì)天然氣管道運(yùn)行優(yōu)化的研究應(yīng)用方面提出更加靈活的思路。依據(jù)文章的對(duì)仿真優(yōu)化算法的研究,運(yùn)用編寫的仿真優(yōu)化軟件對(duì)西氣東輸二線進(jìn)行優(yōu)化多目標(biāo)優(yōu)化計(jì)算,使得西氣東輸二線西段在輸送中的能耗減少了4.43%,壓縮機(jī)開機(jī)臺(tái)數(shù)減少了8臺(tái),達(dá)到了節(jié)能減排的優(yōu)化目的。
[Abstract]:With the construction and production of gas transmission from west to east and Sichuan gas transmission from east to east, a large national gas transmission network system is gradually formed, and the requirements for pipeline operation and dispatching are also being raised step by step. At present, domestic natural gas pipeline operation and management mostly rely on experience. Although the scheme is feasible in most cases, it also has some optimization space. From the point of view of saving energy and reducing operating cost, it is very important to optimize the operation of gas pipeline. In this paper, the multi-objective operation optimization technology of natural gas pipeline is studied by example analysis, combined with two modules of simulation and optimization, combined with dynamic programming algorithm. Through the above research, the steady state simulation optimization model of West-to-East Gas Transmission Line is established, and the simulation results obtained by the simulation module are compared with the simulation results of SPS software to verify its accuracy. After that, the software of multi-objective operation optimization of natural gas pipeline is written to make it have the functions of self-definition simulation and multi-objective optimization scheme calculation (minimum energy consumption and minimum number of compressor operating units). The multi-objective optimal operation scheme of the pipeline is calculated under the special working conditions and compared with the actual operation scheme. On the basis of single objective optimization, please climb another high building and start to study multi-objective optimization, which makes the application of natural gas pipeline operation optimization in actual production more meaningful and more representative. A more flexible way of thinking is also put forward for the research and application of natural gas pipeline operation optimization. According to the research of the simulation optimization algorithm in this paper, the simulation optimization software is used to optimize the multi-objective optimization calculation of the second line of gas transmission from west to east, which reduces the energy consumption of the second section of gas transmission from west to east by 4.43%. The compressor has reduced the number of operating units by 8 units to achieve the purpose of energy saving and emission reduction optimization.
