【摘要】：電網(wǎng)企業(yè)具有資源優(yōu)化配置平臺(tái)的作用,隨著我國(guó)電力消費(fèi)比例、電網(wǎng)建設(shè)投資的日益增長(zhǎng),在國(guó)家節(jié)能減排工作中將占有更加重要的地位。研究表明,在電力系統(tǒng)各個(gè)環(huán)節(jié)中,配電網(wǎng)作為重?fù)p層,節(jié)能潛力最大。因此,利用節(jié)能技術(shù)差異化分析進(jìn)行配電網(wǎng)節(jié)能潛力評(píng)估和節(jié)能規(guī)劃方案制定,對(duì)于節(jié)能工作高效開展具有重要意義。針對(duì)配電網(wǎng)節(jié)能工作,不同的節(jié)能技術(shù)手段作用于同一配電網(wǎng),同樣的技術(shù)手段作用于不同運(yùn)行狀態(tài)下的配電網(wǎng),其降損效果均存在差異性。因此只有認(rèn)真分析電網(wǎng)設(shè)備、網(wǎng)架結(jié)構(gòu)和電網(wǎng)運(yùn)行之間的關(guān)系,才能掌握配電網(wǎng)能耗及其影響因子之間的關(guān)聯(lián)性,從而制定出符合電網(wǎng)降損目標(biāo)的節(jié)能技術(shù)方案,總結(jié)出全面的節(jié)能潛力分析方法使節(jié)能工作更具針對(duì)性。同時(shí),配電網(wǎng)差異化節(jié)能是不僅滿足單條線路不同節(jié)能技術(shù)手段的優(yōu)化組合問(wèn)題,又是滿足節(jié)能經(jīng)濟(jì)性和運(yùn)行條件約束下多條線路的配網(wǎng)多目標(biāo)規(guī)劃問(wèn)題,只有通過(guò)建立合理的規(guī)劃模型,才能從配電網(wǎng)的系統(tǒng)角度實(shí)現(xiàn)節(jié)能規(guī)劃工作的指導(dǎo)意義。本文首先根據(jù)配電網(wǎng)設(shè)備和運(yùn)行情況進(jìn)行了損耗產(chǎn)生機(jī)理分析,并總結(jié)了對(duì)應(yīng)的配電網(wǎng)節(jié)能技術(shù)手段,在此基礎(chǔ)上梳理節(jié)能技術(shù)指標(biāo),形成節(jié)能改造技術(shù)準(zhǔn)則,完成配電網(wǎng)節(jié)能分析體系的建立。其次,針對(duì)配電網(wǎng)節(jié)能潛力評(píng)估缺乏全面系統(tǒng)的定量研究問(wèn)題,本文根據(jù)不同的電網(wǎng)數(shù)據(jù)采集情況,結(jié)合前推回代潮流計(jì)算和灰關(guān)聯(lián)預(yù)測(cè)方法,分別形成了基于典型線路和基于區(qū)域配網(wǎng)的節(jié)能潛力評(píng)估方法,應(yīng)用于不同配電網(wǎng)特點(diǎn)的節(jié)能潛力分析。針對(duì)目前配電網(wǎng)大多只進(jìn)行單條線路不同節(jié)能技術(shù)手段優(yōu)化組合,缺乏系統(tǒng)配電網(wǎng)的經(jīng)濟(jì)性和可靠性規(guī)劃問(wèn)題,本文在滿足電網(wǎng)公司要求下的節(jié)能指標(biāo)和成本約束的條件下,建立基于節(jié)能技術(shù)差異化分析的配電網(wǎng)分區(qū)的二層規(guī)劃模型,完成了節(jié)能改造技術(shù)方案制定和節(jié)能投資優(yōu)化分配。最終根據(jù)對(duì)功能需求的分析,搭建配電網(wǎng)節(jié)能輔助分析軟件平臺(tái),結(jié)合算例說(shuō)明,該軟件可實(shí)現(xiàn)系統(tǒng)配電網(wǎng)的節(jié)能潛力評(píng)估和節(jié)能規(guī)劃工作,具有良好的工程應(yīng)用價(jià)值。
[Abstract]:With the power grid enterprise resource optimization configuration platform role, with the power consumption ratio in China, increasing investment in power grid construction, occupy a more important position in the national energy-saving emission reduction work in. The study shows that in all aspects of power system, distribution network as a heavy loss layer, the energy saving potential. Therefore, the use of energy-saving technology difference analysis of development of distribution network energy saving potential assessment and energy saving plan for energy conservation, is of great significance to carry out energy-saving work. According to the distribution network, energy saving technology different from the same distribution network, distribution network technology means the same in different operation conditions, the loss reduction effect. There are differences therefore. Only a careful analysis of the network equipment, the relationship between the structure and operation of the power grid, in order to grasp the relationship between energy consumption and its influencing factors of distribution network, and system A technical scheme of reducing power loss in line with energy saving goals, summed up the potential of energy saving and comprehensive analysis method to make energy-saving work more targeted. At the same time, the difference of distribution network energy saving is not only to meet the optimization problem of different energy saving technology of a single line, but also meet the distribution lines of energy economy and operation condition the multi-objective programming problem, only through the establishment of reasonable planning model, can from the perspective of the system of distribution network planning to achieve energy-saving significance. Firstly, according to the network equipment and operation of distribution of loss mechanism analysis, and summarizes the methods of energy saving technology of distribution network correspondence, on the basis of energy saving technology index the formation of technological transformation, energy-saving standards, complete the analysis to establish the system of energy distribution network. Secondly, according to the distribution network energy saving potential lack of comprehensive quantitative evaluation Study on the problem, according to the different power grid data acquisition, prediction method combined with power flow calculation and grey correlation, respectively, forming a typical circuit and the energy saving potential of distribution network based on evaluation method based on the analysis of the energy saving potential applied to the different characteristics of the distribution network. In view of the current distribution network mostly only a single line of different energy saving technology optimization, lack of system of distribution network reliability and economy of the planning problem, the index of energy saving and cost constraints to meet the requirements of Power Grid Corp under the condition that the establishment of two level programming model of distribution network partition analysis of energy saving technical differences based on the completion of the technical transformation scheme of energy saving and energy saving investment make optimal allocation. Finally according to the analysis the function demand, build distribution network energy aided analysis software platform, combined with an example, the software can realize the power distribution system The energy saving potential assessment and energy saving planning of the network have good engineering application value.
