【摘要】：電力工業(yè)是我國(guó)能源消耗的主要行業(yè)，我國(guó)配電網(wǎng)線損率與國(guó)外發(fā)達(dá)國(guó)家線損率相比具有一定差距，有效降低配電網(wǎng)損耗對(duì)實(shí)現(xiàn)電力系統(tǒng)節(jié)能降損具有深遠(yuǎn)意義。目前，配電網(wǎng)節(jié)能降損研究中存在兩方面問題：配電網(wǎng)線損管理大多只是對(duì)線損率進(jìn)行計(jì)算和簡(jiǎn)單的統(tǒng)計(jì)，無(wú)法從現(xiàn)有的線損管理及損耗分析中得到影響配電網(wǎng)損耗的重要因素，因而降損工作具有一定盲目性，對(duì)降損措施的優(yōu)選和實(shí)施缺少指導(dǎo)性；配電網(wǎng)降損研究大多針對(duì)的是配電網(wǎng)損耗薄弱環(huán)節(jié)的一個(gè)方面，研究單一降損措施的優(yōu)化實(shí)施方案，但實(shí)際配電網(wǎng)降損必然會(huì)涉及到多種降損措施共同實(shí)施的情況，由于投資成本的限制、綜合降損效益最優(yōu)的要求等，對(duì)單一降損措施的研究無(wú)法有效地得到基于多降損措施的配電網(wǎng)降損方案。為了解決上述問題，本文研究了城市中低壓配電網(wǎng)損耗分析以及降損技術(shù)選擇方法，主要研究?jī)?nèi)容如下： 通過研究配電網(wǎng)技術(shù)損耗的計(jì)算原理，針對(duì)配電網(wǎng)的大量電網(wǎng)參數(shù)，根據(jù)參數(shù)影響配電網(wǎng)主要設(shè)備的技術(shù)損耗則影響配電網(wǎng)技術(shù)損耗的原則，提出配電網(wǎng)損耗影響因素集合，并通過建立輻射狀配電網(wǎng)仿真網(wǎng)絡(luò)得到損耗影響因素對(duì)配電網(wǎng)技術(shù)損耗的影響規(guī)律；基于所提出的損耗影響因素，研究了與其對(duì)應(yīng)的降損措施的降損原理和實(shí)施原則，降損措施能通過改善與之對(duì)應(yīng)的損耗影響因素進(jìn)而達(dá)到降低配電網(wǎng)損耗的目的。 針對(duì)現(xiàn)有配電網(wǎng)損耗分析的研究缺乏對(duì)主要損耗影響因素分析的問題，本文在配電網(wǎng)損耗影響因素的基礎(chǔ)上，通過人工統(tǒng)計(jì)數(shù)據(jù)和SCADA/EMS系統(tǒng)的測(cè)量數(shù)據(jù)來(lái)獲取損耗分析的基本信息；為了提高基本信息獲取的精確性，采用數(shù)據(jù)填充和不良數(shù)據(jù)識(shí)別與調(diào)整方法對(duì)獲取的數(shù)據(jù)進(jìn)行處理；針對(duì)配電網(wǎng)運(yùn)行中的不確定性，基于多場(chǎng)景技術(shù)建立了用于損耗分析的配電網(wǎng)場(chǎng)景與分析場(chǎng)景，針對(duì)分析場(chǎng)景，建立了配電網(wǎng)損耗分析的指標(biāo)體系，并應(yīng)用灰色關(guān)聯(lián)分析法對(duì)生成的分析場(chǎng)景的損耗分析指標(biāo)進(jìn)行關(guān)聯(lián)度與貢獻(xiàn)度的計(jì)算，以此確定出配電網(wǎng)技術(shù)損耗影響因素對(duì)配電網(wǎng)線損率的影響程度，，進(jìn)而確立現(xiàn)狀配電網(wǎng)的重要損耗影響因素。 針對(duì)當(dāng)前配電網(wǎng)降損研究中大多只針對(duì)某一方面進(jìn)行優(yōu)化，無(wú)法對(duì)現(xiàn)狀配電網(wǎng)的多個(gè)薄弱方面進(jìn)行降損優(yōu)化決策的問題，本文研究了多降損措施組合的中低壓配電網(wǎng)優(yōu)化模型及其方法。在現(xiàn)有降損優(yōu)化算法和人工經(jīng)驗(yàn)的基礎(chǔ)上，根據(jù)不同的降損措施種類及其實(shí)施方案，構(gòu)建了用于優(yōu)化決策的降損備選方案集合；通過研究損耗電量的多目標(biāo)效益評(píng)價(jià)，結(jié)合全壽命周期理論建立了能夠反映綜合降損效益的決策目標(biāo)函數(shù)；針對(duì)目前降損優(yōu)化都以建設(shè)費(fèi)用最低為優(yōu)化目標(biāo)，沒有考慮實(shí)際投資限制的問題，建立了以可靠性、安全性和投資限制為主的決策約束條件。所提出的決策方法能夠在選擇配電網(wǎng)降損措施的同時(shí)計(jì)及中低壓配電網(wǎng)的多個(gè)規(guī)劃目標(biāo)：滿足運(yùn)行約束、優(yōu)化降損效益，因而最終決策方法具有最優(yōu)的綜合效益。
